 BUSINESS OF THE MEETING 

Business of the Meeting 

 

 Items of Business 

As set out in the notice of meeting, shareholders of Hydro One will be asked to consider and, as required, vote on the following four matters at the
meeting: 
 1. Financial Statements 
 The audited consolidated financial statements of Hydro One for the fiscal year ended December 31, 2017 and the report of the external auditors on the financial statements will be received. 

2. Election of Directors 
 The
company’s board of directors (the board) currently comprises 15 directors. On January 24, 2018, Ms. Kathryn Jackson informed the Chair of the board of her decision to not stand for
re-election at the company’s 2018 annual meeting of shareholders. The board has approved the reduction in size of the board to 14 members as of the date of the company’s 2018 annual meeting of
shareholders. As such, at the meeting, the shareholders will be asked to elect 14 directors in accordance with Hydro One’s majority voting policy



 (the majority voting policy), which is explained in more detail starting on page 8. All
directors so elected will hold office until the next annual meeting of shareholders or until their successors are elected or appointed. 

Other details respecting the nominees for election as directors are set out under “About the nominated directors” starting on page 8.

 The board recommends that you vote FOR the election to the board of each of the nominated directors. 

3. Appointment of External Auditors 
 The external auditor of Hydro One is KPMG LLP (KPMG), Chartered Professional Accountants, located in Toronto, Ontario. KPMG was initially appointed as the external auditor of Hydro One on August 31, 2015. KPMG has also
acted as the external auditor of Hydro One’s principal subsidiary (Hydro One Inc.) since 2008. Shareholders are being asked to approve the appointment of KPMG as the external auditor of Hydro One for the ensuing year and to authorize the
directors of Hydro One to fix their remuneration.

 The board recommends that you vote FOR the approval of the appointment of KPMG as the external auditors of Hydro One and
authorize the directors of Hydro One to fix their remuneration. 
 4. Advisory Vote on Executive Compensation 

Our compensation program seeks to attract, retain, motivate and reward individuals through competitive pay practices which reinforce Hydro
One’s pay-for-performance philosophy. It is designed to focus employees on developing and implementing strategies that create and deliver value for shareholders.
Hydro One believes that its compensation program is consistent with these objectives, and is in the best interests of shareholders. For detailed disclosure of our executive compensation program, see “Executive Compensation” starting on
page 48. 
 The board has adopted a policy to hold an advisory vote on the approach to executive compensation (say on pay) at each
annual meeting. This shareholder say on pay vote forms an important part of the ongoing process of engagement between shareholders and the board on executive compensation. 

At the meeting, shareholders will have an opportunity to vote on our approach to executive compensation through consideration of the following say
on pay advisory resolution: 


 “Resolved, on an advisory basis and not to diminish the role and responsibilities of the
board of directors, that the shareholders accept the approach to executive compensation disclosed in the management information circular delivered in advance of the 2018 annual meeting of shareholders of the company.” 

This resolution conforms to the form of resolution recommended by the Canadian Coalition for Good Governance and is in the same form as our say on
pay resolution that was approved by the shareholders at our 2017 annual meeting of shareholders. Approval of this resolution requires that it be passed by a majority of the votes cast by shareholders thereon in person and by proxy. Because your vote
is advisory, it will not be binding upon the board. However, the board will take into account the results of the vote when considering future executive compensation arrangements. 

The board recommends that you vote FOR approval of the advisory resolution on Hydro One’s approach to executive compensation. 

At our 2017 annual meeting, the say on pay resolution was approved by shareholders, with shareholders holding 489,688,822 common shares voting in
favour representing approximately 99.76% of the votes cast on the resolution.

 BUSINESS OF THE MEETING 

Information About Voting 

 

 Delivery of Proxy Materials 
 As permitted by Canadian securities regulators, Hydro One is providing shareholders with electronic access to its circular for the company’s annual meeting of shareholders and its 2017 annual report, instead of mailing out
paper copies. This means of delivery is more environmentally friendly and will reduce the cost of printing and mailing materials to shareholders. 
 Shareholders will receive a notice of availability of proxy materials (notice) together with a form of proxy or voting instruction form. The notice provides instructions on how shareholders may access and review an electronic
copy of the circular and how shareholders may request a paper copy. Shareholders who have already provided instructions on their account to receive paper copies of the circular will receive a paper copy of the circular with a copy of the notice




 
regarding its electronic availability. The notice also provides instructions on voting at the meeting. 
 Proxy materials are being sent to registered shareholders directly and will be sent to intermediaries to be forwarded to all non-registered (beneficial) shareholders. We pay the cost of proxy
solicitation for all registered owners and for beneficial owners other than beneficial owners who object to their name and address being given to the company. An objecting beneficial owner will only receive proxy materials if their intermediary
assumes the cost of delivery. 
 Shares Outstanding 

As of March 14, 2018, there were 595,386,711 common shares outstanding, each carrying the right to one vote per common share.


 

  

The Electricity Act, 1998 (Ontario) and our articles preclude any person or company (or
combination of persons or companies acting jointly or in concert), other than Her Majesty the Queen in Right of Ontario, as represented by the Minister of Energy (the Province), from owning, or exercising control or direction over, more than
10% of any class or series of voting securities, including common shares of Hydro One. 


 

 Who Can Vote 
 You
have the right to one vote per common share held on the record date for the meeting, April 3, 2018. 
 Other than the Province, any
person, or an entity controlled by a person, who beneficially owns shares that are, in the aggregate, more than 10% of the eligible votes that may be cast at the meeting, may not vote any of their shares. 

As of March 14, 2018, our directors and executive officers were not aware of any person or entity who beneficially owns, directly or




 
indirectly, or exercises control or direction over more than 10% of our outstanding common shares, other than the Province, which holds 282,412,648 common shares (representing approximately 47.4%
of the outstanding common shares). 
 Under a governance agreement the company entered into with the Province on November 5, 2015
(the governance agreement), the Province is required to vote in favour of the nominees identified in this circular except in the case of contested director elections and where the Province seeks to replace the board in accordance with the
governance agreement by withholding votes or voting for removal.

 BUSINESS OF THE MEETING 

About the nominated directors 

 

 This year, 14 directors are proposed for election to our board. On January 24, 2018,
Ms. Kathryn Jackson informed the board chair of her decision to not stand for re-election at the company’s 2018 annual meeting of shareholders. The board has approved the reduction in size of the
board to 14 members (from the current 15 members) as of the date of the company’s 2018 annual meeting of shareholders. 
 The
director profiles, starting on page 9, tell you about each director’s skills, experience and other important things to consider, including how much equity in Hydro One they own and any other public company boards they sit on. 

Just as important are the skills these directors have as a group. These directors have been selected based on their abilities, independence,
commercial experience, governance expertise with public companies, customer service, and knowledge about the electricity sector and public policy. You can learn more about our expectations for directors and how the board functions beginning on page
26. 
 Independence 
 Of the 14 nominated directors, 13
are independent. For Hydro One’s purposes, an independent director is one who is independent of Hydro One and independent of the Province. Directors will be independent of Hydro One if they are independent within the meaning of all Canadian
securities laws governing the disclosure of corporate governance practices and stock exchange requirements imposing a number or percentage of independent directors. Pursuant to Canadian securities laws, a director who is “independent”
within the meaning of applicable securities laws is one who is free from any direct or indirect relationship which could, in the view of the board, be reasonably expected to interfere with a director’s independent judgement, with certain
specified relationships deemed to be non-independent. A director will be “independent of the Province” if he or she is independent of Hydro One under Ontario securities laws governing the disclosure
of corporate governance practices, where the Province and certain specified provincial entities are treated as Hydro One’s parent under that definition, but excluding current directors where the relationship ended before August 31, 2015.
The governance agreement requires each of the directors, other than the CEO, to be both independent of Hydro One and independent of the Province.




 
The Chair of Hydro One is independent of Hydro One and the Province. 
 None of the
independent directors have ever served as an executive of the company. Having an independent board is one of the ways we ensure that the board is able to operate independently of management and make decisions in the best interests of Hydro One and
our shareholders. Mayo Schmidt is not an independent director because of his role as the company’s President and CEO. 
 Length of Service 

Each of the nominated directors is currently a member of the board. All of the nominees were initially elected to the board on August 31, 2015
in connection with the formation of the company and were re-elected to the board at our 2017 annual meeting of shareholders. If elected, each nominated director will serve until the earlier of our next annual
meeting of shareholders or until his or her successor is elected or appointed. 
 Prior to becoming directors of the company, two of the
independent director nominees and the board chair previously served on the board of directors of the company’s wholly owned subsidiary, Hydro One Inc. Ms. Gale Rubenstein and Mr. George Cooke have served on the board of directors of
Hydro One Inc. since March 30, 2007 and January 26, 2010, respectively. Mr. David F. Denison, the board chair, served on the board of directors and as the chair of the board of Hydro One Inc. since April 16, 2015. The board
benefits from the continuity and insight of these director nominees. 
 Majority Voting Policy 

The board has adopted a majority voting policy for the election of directors. This policy provides that in an uncontested election, any nominee for
director who receives more withheld votes than for votes will immediately tender his or her resignation for consideration by the board. The board will review the matter and take whatever actions it determines are appropriate in the
circumstances. The director who has tendered his or her resignation pursuant to this policy will not participate in any deliberations of the committee or the board regarding the resignation. In this instance, the other directors shall consider, and
within 90 days of the election meeting, determine whether or not to accept the resignation. 

 

  

The Province and Hydro One entered into the governance agreement on closing of Hydro One’s
initial public offering on November 5, 2015 which addresses the role of the Province in the governance of Hydro One and, among other things, requires Hydro One to maintain a majority voting policy for director elections. For more details about
the governance agreement, see the description of our corporate governance practices starting on page 29.

MANAGEMENT INFORMATION CIRCULAR HYDRO ONE LIMITED    TSX: H





                     










 

 Under the governance agreement, the Province may not withhold its votes for the nominees proposed for
election in an uncontested election unless the Province withholds from voting for all nominees other than the CEO and, at the Province’s discretion, the chair. Where directors have received a majority withheld vote as a result of the Province
withholding its vote from their election in an uncontested election and have tendered their resignations, the board will take whatever actions it determines are appropriate, and the directors who received a majority withheld vote may participate in
that determination. A resignation will be accepted absent exceptional circumstances and is effective when accepted by the board. A press release disclosing the directors’ determination shall be issued promptly following such determination and,
if the resignation is not accepted, will include the reasons for non-acceptance. 
 The majority
voting policy does not apply to a contested election where the number of candidates for director validly nominated exceeds the number of directors to be elected at that meeting.

 BUSINESS OF THE MEETING 

Notes: 

	1	The directors of Hydro One are also directors of Hydro One Inc. and the two boards and each committee thereof hold joint meetings. See also “Director
Attendance” on page 25. While Ms. Kathryn Jackson is not standing for re-election at the company’s 2018 annual general meeting, her 2017 meeting attendance record was as follows: (a) board
meetings: 11 of 13 or 85%; (b) Governance Committee meetings: 4 of 4 or 100% and (c) Health, Safety, Environment and Indigenous Peoples Committee meetings: 4 of 4 or 100%. 


	2	The equity ownership of each director is presented as at March 17, 2017 in respect of 2016 and March 14, 2018 in respect of 2017. The value of director DSUs
is calculated using the closing price of our common shares on the TSX on the date of grant of the director DSU being: 

  

			
		
	 Date of Grant
	  	TSX Closing Value
	  
 December 31, 2015
	  	$22.29
	 March 31, 2016
	  	$24.31
	 March 31, 2016 (dividend equivalents)
	  	$23.48 (value date of March 18, 2016)
	 June 30, 2016
	  	$25.96
	 June 30, 2016 (dividend equivalents)
	  	$24.49 (value date of June 15, 2016)
	 September 30, 2016
	  	$25.90
	 September 30, 2016 (dividend equivalents)
	  	$25.62 (value date of September 15, 2016)
	 December 30, 2016
	  	$23.58
	 December 30, 2016 (dividend equivalents)
	  	$23.22 (value date of December 15, 2016)
	 March 31, 2017
	  	$24.25
	 March 31, 2017 (dividend equivalents)
	  	$23.50 (value date of March 15, 2017)
	 June 30, 2017
	  	$23.23
	 June 30, 2017 (dividend equivalents)
	  	$23.37 (value date of June 14, 2017)
	 September 29, 2017
	  	$22.72
	 September 29, 2017 (dividend equivalents)
	  	$22.62 (value date of September 13, 2017)
	 December 29, 2017
	  	$22.40
	 December 29, 2017 (dividend equivalents)
	  	$22.49 (value date of December 13, 2017)

 Fractional director DSUs can be granted, with fractions computed to three decimal places. The number of director DSUs in
this table have been rounded. Mr. Schmidt, as President and CEO, is not eligible to receive director DSUs as he is not a non-employee director. 

	3 	The value of the common shares held by each applicable director is calculated using the acquisition cost per share of such common shares on the date of purchase. 


	4 	Pursuant to the corporate governance guidelines, each non-employee director is expected to achieve his or her share ownership target (being 3x the annual board membership
retainer) within the later of six years following the closing of the company’s initial public offering and the date of appointment to the board. The current corporate governance guidelines require a
non-employee director’s share ownership to be calculated on December 31st each year (based on the original acquisition cost or grant value) and compared to the share ownership requirement.
Mr. Schmidt, as the President and CEO, is subject to different share ownership requirements. For details on the share ownership requirements applicable to him, and the status of his compliance with them, see pages 55 and 71. 


	5 	The status under share ownership requirement is calculated by dividing the directors’ total value of common shares and director DSUs as of December 31st of the relevant year by the amount of the annual retainer
being $160,000 for 2017 for all directors (other than the Chair) and $260,000 for 2017 for the Chair.

in charge of a principal business unit, division or function including sales, finance or production; or (iv) an individual performing a policy making function (each of (i), (ii), (iii) and (iv), an executive officer) of any
company that, during such service or within a year after the end of such service, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or
compromise with creditors or had a receiver, receiver manager or trustee appointed to hold its assets; 

  

	·	 	is, or within the last 10 years has served as, a director, chief executive officer or chief financial officer of any company that, during such service or as a result of an event that occurred
during such service, was subject to an order (including a cease trade order or similar order or an order that denied access to any exemption under securities legislation), for a period of more than 30 consecutive days; or 


 

	·	 	within the last 10 years has become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any proceedings, arrangement or

In May 2004, Saskatchewan Wheat Pool Inc. (SWP), a predecessor to Viterra Inc., initiated a disposition of its hog operations, which had been
carried on through certain of its subsidiaries, through a court supervised process under the Companies’ Creditors Arrangement Act (Canada). On April 12, 2005, the Saskatchewan Financial Services Commission issued a cease
trade order against four of SWP’s subsidiaries for failing to file the required annual continuous disclosure documents. The cease trade order was revoked on October 18, 2010 pursuant to 

 



 
Viterra Inc.’s application to effect a re-organization of the entities in question. Mr. Schmidt served as an officer and/or director of these
entities at the time. 
 Mr. Orsino was a director of CFM Corporation from July 2007 until his resignation in March 2008. In April
2008, CFM filed for protection under the Companies’ Creditors Arrangement Act (Canada). 
 Ms. Peverett was a director of
Postmedia Network Canada Corp. between April 2013 and January 2016. On October 5, 2016, within one year of Ms. Peverett’s resignation from the board of directors, Postmedia completed a recapitalization transaction (the
recapitalization transaction) pursuant to a court approved plan of arrangement under the Canada Business Corporations Act. As part of the recapitalization transaction, approximately US $268.6 Million of debt was exchanged for
shares that represented approximately 98% of the outstanding shares at that time. Additionally, Postmedia repaid, extended and amended the terms of its outstanding debt obligations pursuant to the recapitalization transaction. 

Penalties or Sanctions 
 None of the directors of Hydro One have
been subject to any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or have entered into a settlement agreement with a securities regulatory authority or been subject to any other
penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor making an investment decision. 

Director Attendance 
 Directors are expected to attend board
meetings, meetings of the committees on which they serve and the annual meeting of shareholders. The average attendance of all directors at board and committee meetings in 2017 was 96% and 98%, respectively.

 Director Compensation 
 The by-laws of the company provide that directors may receive remuneration for their services as determined by the board and be reimbursed for all expenses incurred in fulfilment of their
duties, including travel expenses. Hydro One’s director compensation policy and levels were originally established in 2015 (prior to the company’s initial public offering (IPO)) and no changes were made in 2016 or 2017. The compensation
levels were set near or below the median director compensation levels of the following peer group of large Canadian utility and other Canadian pipeline and storage companies: 

 

			
	 Fortis Inc.
	  	TransAlta Corporation
	 Emera Incorporated
	  	Pembina Pipeline Corporation
	 ATCO Ltd.
	  	Inter Pipeline Ltd.
	 Keyera Corp.
	  	AltaGas Ltd.


 

 The company’s director compensation, travel and expense policy applies to non-employee directors. Mr. Schmidt, as President and CEO, does not receive any separate compensation for his service on the board. Details regarding Mr. Schmidt’s compensation can be found under
“Executive Compensation” starting on page 70. 
 Directors are required to receive 50% of their annual director retainer as an
equity component in the form of director deferred share units (director DSUs). They may elect to be paid up to 100% of the cash component in the form of director DSUs. Hydro One has adopted a
non-employee director deferred share unit plan providing for awards of director DSUs to Hydro One directors other than the President and CEO. A director DSU is an award that entitles the participant to receive
an amount equivalent to the value of a common share at settlement following termination of service with Hydro One and its subsidiaries. Director DSUs vest immediately and accrue dividend equivalents when dividends are paid on the common shares.

 Directors also receive a reasonable per meeting allowance for travel and other expenses incurred to
attend meetings in accordance with a company approved policy. No additional compensation is paid to directors to prepare for board or committee meetings. For 2017, the directors of Hydro One received all of the equity component of their annual
director retainer payable in director DSUs. 
 In August 2017, the chair of the governance committee of the board engaged Hugessen
Consulting Inc. to conduct a compensation benchmarking review for non-executive directors of Hydro One using the same peer group of companies used for executive compensation benchmarking as described on page
59. As a result of the review, the governance committee recommended to the board, and the board approved, the following changes to the company’s director compensation policy effective on January 1, 2018: a $25,000 increase to the
directors’ annual retainer (to $185,000), a $70,000 increase to the Chair of the board’s annual retainer (to $330,000) and an increase of $5,000 for the Chairs of the audit committee and human resources committee (to $25,000 each). The
increase in 


 
directors’ compensation will bring the Hydro One board closer to, but still below median of, this broader peer group. 

Director Share Ownership Requirements 
 Hydro One believes that
the interests of shareholders and directors are better aligned when directors hold significant investment in Hydro One. The corporate governance guidelines require directors who are non-executives of Hydro One
to retain a minimum holding of common shares or director DSUs equal to three times (3x) their total annual board retainer (calculated including the equity portion), valued at the original grant value or acquisition cost, by the later of six years
following the closing of the company’s initial public offering on November 5, 2015 and the date of his or her appointment to the board. The ownership requirement for directors in 2017 was $480,000, except for the board chair, whose share
ownership requirement was $780,000. As a result of the change to the company’s director compensation policy effective on January 1, 2018 (as discussed in the immediately preceding paragraph), effective on January 1, 2018 the ownership
requirement for directors is $555,000, except for the board chair, whose share ownership requirement is $990,000.

 CORPORATE GOVERNANCE 

 

 About the Governance Agreement 

In connection with the November 2015 closing of the initial public offering of the company, Hydro One entered into the governance agreement with the
Province, which describes certain principles that govern how Hydro One will be managed and operated, including that the Province, in its capacity as a holder of common shares, will engage in the business and affairs of Hydro One as an investor and
not as a manager. Among other things, the governance agreement: 
  

	·	 	requires that except for the CEO, all board members be independent of Hydro One and independent of the Province; 


 

	·	 	addresses the director nomination process, including the requirement to maintain a board of between 10 and 15 members and prescribing the maximum number of directors that may be nominated by the
Province (please refer to page 38);





	·	 	requires Hydro One to maintain a majority voting policy for director elections and restricts the Province’s ability to withhold from voting for directors except where the Province replaces the
entire board other than the CEO and, at the Province’s discretion, the board chair; 

  

	·	 	requires approval by special resolution of the directors of the appointment and annual confirmation of the CEO, the board chair and changes to key governance practices of the company;


  

	·	 	restricts the right of the Province to exercise certain shareholder rights, such as to requisition a shareholder meeting to consider a fundamental change, or to solicit others to exercise rights
which the Province is restricted from exercising; and 

  

	·	 	restricts the acquisition of voting securities by the Province but grants the Province pre-emptive rights with respect to future issuances of voting
securities. 


 

  

Approval of the board by way of a special resolution of at least two-thirds of the votes
cast at a board meeting or the unanimous written consent of all directors is required in order to make changes to the director skills matrix, board diversity policy, majority voting policy, stakeholder engagement policy, corporate disclosure policy,
corporate governance guidelines, mandate for the Hydro One Ombudsman, mandates of the board and its committees, position descriptions for the CEO, the board chair, the directors and the committee chairs, code of business conduct, whistleblower
policy, executive share ownership guidelines and anti-hedging policy and compensation recoupment policy. 


 

 A copy of the governance agreement has been filed on SEDAR and is available under Hydro One’s
profile at www.sedar.com. Additional details respecting the terms of the governance agreement are also provided in Hydro One’s most recent Annual Information Form that is also available under Hydro One’s profile at www.sedar.com.

 The structure and role of the board is consistent with the best practices of leading Canadian publicly listed companies and the
governance agreement. 
 Board Mandate 
 The mandate of the board is to oversee the business and affairs of Hydro One. As part of that mandate, the board is responsible for overseeing the interests of Hydro One’s customers which are fundamental to, and inform, Hydro
One’s business and strategy. The board approved the mandate of the Hydro One Ombudsman who reports directly and regularly to the governance committee of the board. The board also receives comprehensive customer service reports which are a
standing item at every regular board meeting. The board has adopted a written mandate, which is attached as Schedule “A” to this circular.



 Board’s Role in Strategy 

The board oversees our strategic direction and holds management accountable for executing the company’s strategy. The board participates in our
strategic planning process throughout the year by reviewing and approving our strategic plan (taking into account the opportunities and risks of our business), regularly scrutinizing management’s execution of business plans and their results
and annually assessing the company’s performance against financial and other objectives established in the company’s business plans, past performance and industry peers. The board dedicates at least one meeting every year for these
purposes. 
 Board’s Role in Overseeing Risk 

Our risk oversight framework sets the foundation for overseeing the identification and management of our principal business risks. The board has
delegated to the audit committee the responsibility of reviewing and approving our major risk policies, our enterprise risk management framework and identifying the list of key risks that the company plans to prioritize in the next year. The audit
committee also assesses the key risks facing the company. 
 The board retains overall responsibility for overseeing the management of
risk for the company. The audit committee assists the board by ensuring that the risks identified are allocated where appropriate to the board committees, consistent with the general


 



         


 


  

			
	 30    2018
MANAGEMENT INFORMATION CIRCULAR HYDRO ONE LIMITED    TSX: H





                     









 
scope of their respective responsibilities. As part of their assessment, the committees are expected to consider the likelihood and magnitude of the specific risks within their mandates and,
through committee cross-appointments and other procedures, the potential compounding effects of risks. The audit committee reviews the company’s risk profile and risk tolerances annually with the officers of the company while the President and
CEO has ultimate accountability for managing the company’s risks. 
 To assist the board in identifying the key risks faced by the
company, management presents an assessment of key risks and risk mitigation/management to the board on an annual basis along with how such risks are mitigated or managed. The last assessment was completed on August 8, 2017. A comprehensive
description of all of the key risks facing the company is provided in the company’s Annual Information Form and Management’s Discussion and Analysis for the fiscal year ended December 31, 2017 and in other filings made by the company
with the securities regulatory authorities in Canada. The board’s assessment of the relative significance of these risks may change over time. 
 Internal Controls and Management Information Systems 
 The board oversees the integrity and effectiveness of our
management information systems and internal controls and approves our internal control policy. The work is carried out mainly by the audit committee, which oversees our key controls over financial reporting, certifications of internal controls over
financial reporting and disclosure controls and procedures. The audit committee meets separately with the Chief Financial Officer (the CFO) and head of internal audit and also with the external auditors without management present,
receives regular reports from management and the internal audit department on our internal controls and any significant deficiencies in controls, and oversees Hydro One’s code of business conduct (the code of business conduct) and
Hydro One’s whistleblower policy (the whistleblower policy), which includes procedures for receiving and resolving complaints about accounting or auditing matters. 

Talent Management: Leadership Development, Succession Planning and Performance Assessment 

Our talent management strategy focuses on developing our executive talent to support our long term business strategy and ensure management
succession. The board oversees development and implementation of our leadership development strategy with the support of the human resources committee. The human resources committee reviews the qualifications, experience and capabilities of
executives on the succession plan, reviews




 
candidates for our most senior roles, including the President and CEO, and ratifies the appointments of the President and CEO’s direct reports who hold an executive vice president level
position. 
 The human resources committee reviews the President and CEO’s assessment of the performance of his direct reports who
hold an executive vice president level position. The human resources committee also assesses the President and CEO’s performance against his mandate and the short and long term objectives that were set at the beginning of the year. 

Ethical Business Conduct 
 The
company has a written code of business conduct that applies to all employees, directors and officers of Hydro One and its subsidiaries. 

The code of business conduct sets out Hydro One’s core values and establishes standards to define how employees, officers and directors of
Hydro One should act. The code of business conduct addresses, among other things, health and safety matters, conflicts of interest, discrimination and harassment, confidentiality, insider trading, environmental protection, safeguarding Hydro
One’s assets (including accounting and financial reporting) and relationships with outside stakeholders including investors, customers, public officials and third parties, conduct during investigations and compliance and reporting obligations.
The full text of the code of business conduct can be found on Hydro One’s website at www.HydroOne.com or is available under Hydro One’s profile on SEDAR at www.sedar.com. 

The board monitors compliance with the code of business conduct through the audit committee. Any actual, potential or suspected violation of the
code of business conduct can be reported anonymously to the company’s corporate ethics officer, as confidential designee of the company, in accordance with the whistleblower policy. 

Whistleblower Policy 
 The
whistleblower policy is designed as a safeguard against threats to the integrity of our financial reporting, threats to health and safety, wrongdoing by employees, representatives and business partners and actual, potential or suspected violations
of our code of business conduct and applicable laws. Employees concerned about any of these matters are encouraged to discuss the matter with their supervisor and may report concerns anonymously through the company’s independent third-party
service provider at www.clearviewconnects.com. The whistleblower policy protects employees who make a report in good faith. All reports are investigated internally or by an

 CORPORATE GOVERNANCE 

 

 independent external party, and appropriate action is taken. The audit committee reviews all matters
reported under the whistleblower policy and their disposition. 
 Stakeholder Engagement 

The company is committed to understanding the interests of and maintaining and enhancing long term relationships with its investors, regulators,
governments, creditors, employees, customers, suppliers, non-governmental organizations and other stakeholders and communities in which the company operates. The board has adopted a stakeholder engagement
policy in order to promote open, effective and sustained dialogue with stakeholders consistent with the company’s insider trading policy, the corporate disclosure policy and with the company’s obligations to provide fair disclosure and
maintain effective disclosure controls and procedures. The board, or an appropriate committee of the board, reviews the content of the company’s major communications to the investing public, including, without limitation, quarterly and annual
reports, earnings releases, management’s discussion and analysis, information circulars, the annual information form and any registration statements or prospectuses that may be issued, filed or otherwise distributed. Shareholders may make their
views known through individual voting for directors, the annual say on pay advisory vote and other matters submitted to shareholders for approval. 
 Below is a summary of some of the important strides made by the company in 2017 with some of its largest stakeholders: 

(a) Customers: 
 Based on
customer feedback received, Hydro One has designed a new bill which includes an easy-to-understand and easier to read format, new visuals to help customers better
understand their usage and more customer friendly language. 
 (b) Large Customers: 

In addition to the strong operational performance for residential and small business customer segments, a number of advances have been made in the
large customer segment as well. In the most recent annual survey, overall satisfaction with Hydro One increased to 87% in 2017. These positive results can be partially attributed to organizational alignment as it relates to large customers, enhanced
customer reporting, and a renewed commitment to customer advocacy. 
 (c) Communities: 

To demonstrate Hydro One’s renewed commitment as a customer-focused company, the company’s Community Relations team continues




 
to support Hydro One’s forestry and capital projects by building relationships with the local communities across the province through proactive, transparent, and collaborative communication.

 (d) Indigenous Peoples: 
 Commencing in 2017, Hydro One offered a new First Nations Conservation Program for a 4-year period to 47 First Nation communities served by Hydro One who were not served by the Aboriginal
Conservation Program which was offered by the Independent Electricity System Operator from 2013 to 2015. In addition, during 2017, Hydro One delivered two provincial and five regional Indigenous Peoples engagement sessions where it met with all 88
First Nation communities served by Hydro One Networks Inc. and all 29 Métis Councils in Ontario. 
 Hydro One is committed to
increase Indigenous cultural awareness among its employees at all levels and more particularly wants to ensure its employees have the skills, knowledge and resources necessary to develop and maintain relationships with Indigenous peoples and
communities based on mutual respect and trust. As such, Hydro One implemented a four pronged Indigenous Relations Leadership Learning Program in the third quarter of 2017. As at December 31, 2017, 88 of 95 (93%) of employees who are
director-level and above completed the online Indigenous Cultural Awareness Course and the in-class training course was delivered to 100% of employees who are director-level and above. 

On June 21, 2018 during National Aboriginal Day, Hydro One will launch an Indigenous Network Circle (INC), a new employee resource group for
the company’s Indigenous employees. 
 Board Structure 
 Board Chair 
 The board chair is responsible for leading the board in carrying out its duties and responsibilities
effectively, efficiently and independent of management. Under the governance agreement, the board chair is nominated and confirmed annually by special resolution of the board. The board chair is required to be separate from the President and CEO and
must be independent of Hydro One and independent of the Province. 
 The board chair’s key responsibilities include providing
leadership to the board to enhance the board’s effectiveness for certain accountabilities, including supervision of management of the company and oversight of the relationships between the board, management, shareholders, customers and other
stakeholders. The board chair presides over all board meetings, chairs all sessions with the independent directors, supports and assists in director orientation

	 and continuing education and ensures that an appropriate system is in place to annually evaluate the performance of the board as a
whole.
  
 President and CEO

 
 The President and CEO is responsible for managing and providing strategic
direction to Hydro One, including the development and implementation of plans, policies, strategies and budgets for the growth and profitable operation of the company. Under the governance agreement, the appointment of the President and CEO is
confirmed annually by special resolution of the board.
	  	 Board Committees
  

Four standing committees assist the board in carrying out its duties and responsibilities. Descriptions of the committee mandates and membership are
included in the circular starting on page 41. Except for the board chair and the President and CEO, all directors serve on at least one board committee. The board chair regularly attends each committee meeting by standing invitation. The President
and CEO does not sit on any board committees because he is not independent; however he regularly attends and participates at committee meetings.


  

Copies of the board committee mandates are posted in the corporate governance section of our website at
https://www.hydroone.com/about/corporate-information/governance 


 

 Committee Chairs 

Committee chairs must be independent directors. They are responsible for providing leadership to the committee, facilitating the functioning of the
committee independently of management and reporting to the board on its activities and its compliance with the committee’s mandate, and providing input to the board chair and the chair of the governance committee on succession planning for
their position and each committee, generally. 
 Position Descriptions 

The board has adopted written position descriptions for the board chair, the President and CEO, directors and the chair of each board committee.

 Orientation and Continuing Education 
 The company
has implemented an orientation program for new directors in accordance with Hydro One’s corporate governance guidelines (the corporate governance guidelines).



 When new directors join the board, they are provided with briefings by management on the key aspects
of the company’s business affairs, activities, corporate governance structure and its policies and procedures. In addition, directors are also provided with access to the company’s secure board portal which provides online access to all
meeting materials required for the meetings and the director’s information manual which contains information on board and committee mandates, position descriptions for the board chair, President and CEO, committee chairs and individual
directors, and copies of the company by-laws and corporate governance guidelines. 
 The company
also supports continuing education opportunities outside the company and each director is encouraged to attend external forums, conferences, seminars and education programs dealing with subject matters that are applicable to the member’s role
on the board or its committees or to increase the member’s knowledge of the company’s industry and other areas of interest relevant to the company’s businesses and affairs. Approval by the board chair or the chair of the governance
committee is required to attend such programs with the financial support of the company.

 Notes: 
  

	1	Mr. Hinds was previously a director and the chair of the IESO and Ms. Jamieson was previously a director of Ontario Power Generation Inc., but because those
relationships ended before August 31, 2015, they are independent of the Province within the meaning of the governance agreement. 

  

	2	Ms. Jackson is not standing for re-election at the company’s 2018 annual meeting of shareholders. 


 

	3	Mr. Schmidt is not independent because he is the President and CEO of Hydro One. 


 

 At each meeting of the board, the independent directors hold an in camera meeting at which members of
management are not present unless the board chair otherwise determines. During 2017, 13 such in camera sessions without management were held. Each committee of the board also holds regular in camera meetings, unless the chair of the applicable
committee determines otherwise. As well, the audit committee meets regularly, but no less than quarterly. The audit committee also holds in camera sessions at each meeting of the committee without management or
non-independent directors present, unless otherwise determined by the audit committee chair. These sessions encourage open and candid discussion among the directors.



 In 2017, the audit committee met with the head of the company’s internal audit function and the
external auditors in separate in camera executive sessions during each of its quarterly meetings to discuss any matters that the audit committee or any of these groups believes should be discussed privately. The audit committee met in camera with
the CFO during its May 2017 quarterly meeting and met in camera with the SVP, Finance (acting in the capacity of CFO) during its August 2017 quarterly meeting. The SVP, Finance (acting in the capacity of CFO) also met privately with the audit
committee chair prior to each audit committee meeting in 2017.

 CORPORATE GOVERNANCE 

 

 Government/regulatory/public policy:
experience in, or a strong understanding of, the workings of government and public policy in Canada and internationally; 

Information technology: experience in information technology with major
implementations of management systems; 
 Risk management: experience or
understanding of enterprise risk management systems, procedures and practices; 
 Business transformation: experience driving strategic direction changes and leading growth of an organization; 
 Large company senior executive: experience as a chief executive officer, chief operating officer or chief financial officer of a publicly listed company or major
organization. 
 Nomination of Directors 
 The
governance committee identifies qualified candidates for election to the board, having regard for their independence, background, experience and skills and the alignment of such candidates’ experience and skills with Hydro One’s needs.
Under the governance agreement, the Province is entitled to nominate the number of directors that is equal to 40% of the number of directors to be elected (rounded to the nearest whole number). The governance committee communicates with and makes
recommendations to the Province respecting potential candidates for director, including potential candidates for nomination by the Province. The Province has no obligation to nominate any of the individuals recommended as one of its director
nominees. 
 Director nominees must meet the director qualification standards set out in the governance agreement, including the
prescribed director independence requirements and requirements under securities laws and applicable stock exchange rules. If a proposed nominee is replacing an existing director, under the governance agreement, the nominee must also, when taking
into account existing directors and other confirmed nominees, enable the board to satisfy the board composition requirements of Hydro One’s director skills matrix, board diversity policy and other governance standards. A majority of the board
must at all times be resident Canadians. 
 Not later than 60 days prior to the date by which proxy solicitation materials must be mailed
for Hydro One’s annual meeting of shareholders, each of the Province and the governance committee will notify the other of its proposed director nominees. If a proposed nominee is not already a director of Hydro One or is then a director but
whose circumstances have materially changed in a way that would affect whether she or he would continue to meet the director qualification standards under the governance agreement, then the Province or the committee, as the case may be, will have 10
business days to confirm that nominee or reject that nominee on the basis that the nominee does not meet those director qualification standards.



 If a director nominee of the Province or the governance committee is rejected, the Province or the
committee will be entitled to nominate additional candidates until a nominee is confirmed by the other. If no replacement nominee is confirmed for a director who was expected to depart from the board and that director does not resign, that director
shall be re-nominated. The Province and the committee will use commercially reasonable efforts to confirm director nominees prior to the date by which proxy solicitation materials must be mailed for the annual
meeting of shareholders. 
 The Province is required under the governance agreement to vote in favour of all director nominees of Hydro
One. That obligation is subject, however, to the Province’s overriding right to withhold from voting or otherwise seek a shareholder meeting to remove and replace the entire board, including in each case its own director nominees but excluding
the CEO and, at the Province’s discretion, the board chair. 
 Board Renewal and Term Limits 

The company’s board is committed to a process of renewal and succession planning for directors. The board has adopted term limits on board
service and a mandatory retirement age, which are set out in the corporate governance guidelines. 

Non-executive directors cannot stand for re-election 12 years after
the date on which the director first began serving on the board of directors of Hydro One or any of its subsidiaries, except in special circumstances (including if necessary to facilitate orderly board renewal) on the recommendation of the
governance committee. No director shall be appointed or elected as a director after that person has reached 75 years of age, unless otherwise determined by the board. Additionally, after a director has held the position of committee chair for a
period of four years, the governance committee will review and consider whether a change to the committee chair would be appropriate. 
 Diversity Policy 

The board has adopted a board diversity policy (the diversity policy) which formalizes the company’s commitment to diversity and its
desire to maintain a board comprising talented and dedicated directors whose skills, experience, knowledge and backgrounds reflect the diverse nature of the business environment in which it operates, including an appropriate number of female
directors. The board aspires towards a board composition in which each gender comprises at least 40% of the directors on the board. Currently, as to gender, the board includes six female directors (40%). Following the meeting, assuming all director
nominees are elected, the board will include five female directors (35.7%) as Ms. Kathryn Jackson is not standing for re-election.

 In considering the composition of the board and the identification of qualified nominees for election
as directors, the governance committee assesses annually the diversity policy’s effectiveness in promoting a diverse board. In 2017, Mr. Denison, as board chair, became a member of the 30% Club, an organization supporting gender balance on
boards. 
 In addition to the board’s formal diversity policy, Hydro One strives to ensure an inclusive corporate culture where all
employees are valued and have equal access to opportunities. Hydro One also endeavors to ensure that its gender diversity is appropriately reflected at all levels of the organization, including executive positions after taking into account all
relevant factors, such as merit, capability and equal treatment of employees. In 2017, the company implemented a new Diversity and Inclusion Strategy consisting of initiatives involving five key categories. These categories and specific actions
taken in respect of each category are described below: 
  

	(i)	Workforce planning: We are currently working on a Workforce Planning Strategy which will explicitly consider Hydro One’s focus on Diversity and Inclusion. 


 

	(ii)	Recruitment: We continue to focus on recruiting more women into executive roles. In 2017, we increased the number of women in vice president and above roles by over 10% to 33%.


  

	(iii)	Succession planning: As part of our succession planning process, reporting and metrics now include diversity statistics to assist in raising awareness and tracking our progress.


  

	(iv)	Education and leadership development: An initial framework for a Women in Leadership program has been developed and the program will be launched in 2018. In November 2017, Hydro One held a
Women in Trades, Technology & Engineering (WTTE) Symposium with over 300 participants in attendance. The objective of the symposium was to highlight the role of men in driving gender equity. 


 

	(v)	Cultural guidance and outreach: 

 (a) During
2017, the Catalyst Accord was signed to demonstrate Hydro One’s public commitment to gender parity. Catalyst is a global non-profit organization focused on accelerating progress for women through
workplace inclusion. Through the Accord, Catalyst issued a call to action from Canadian corporations to increase the overall proportion of board seats and executive officer roles for women to 30% by the end of 2022. By signing the Accord, Hydro One
committed to maintaining at least 30% female board members and 30% female executives.



 (b) Phase one of Hydro One’s Diversity & Inclusion Effectiveness
Review was completed. The review is made up of three key phases: 
 1. Analysis of existing diversity and inclusion data,
policies and the talent management life cycle; 
 2. A company-wide diversity and inclusion survey designed to gain
insight and learn from our current situation; and 
 3. Focus groups and executive interviews to further explore areas of
opportunity. 
 (c) A first meeting was held with the Power Workers’ Union, the Society of United Professionals
(formerly “The Society of Energy Professionals”) and the Canadian Union of Skilled Workers to discuss collaboration on diversity and inclusion. 

(d) An Indigenous Network Circle Workshop was held in September 2017 bringing together 30 Indigenous employees from across
Hydro One to discuss their experiences and gain agreement on creating a new employee resource group. All Indigenous employees agreed to the creation of the Indigenous Network Circle (INC) and work is underway to launch this initiative on
June 21, 2018 during National Aboriginal Day. 
 As at March 14, 2018, approximately 33% executives (those who hold a vice
president role and above or equivalent) (11 out of 33) across Hydro One, including one of seven executive officers, are women. See the company’s most recent Annual Information Form for a list of the executive officers of Hydro One. 

Other than as committed in signing the Catalyst Accord, Hydro One has not yet set targets for the percentage of women in executive positions and
the board has not yet made any determination as to whether or not targets should be set. The human resources committee’s 2018 work plan includes the executive leadership team consulting with the appropriate board committee(s) to review the
level of gender diversity in executive positions and make a determination regarding targets.

 CORPORATE GOVERNANCE 

 

 Service on Other Boards 
 Limit on Directorships 
 The company recognizes that the board can benefit when a director also serves on the
board of another company. However, as directors are expected to devote the time necessary to fulfill their responsibilities, a director’s acceptance of additional positions as a corporate director of
for-profit corporations is subject to the board’s review and we limit the number of public company boards they can serve on (in each case, excluding service on the board of the company and the board of
directors of Hydro One Inc.). Each non-management director is expected to hold no more than four public company directorships and the President and CEO should not hold more than one such directorship.

 In addition, the audit committee mandate provides that no member of the audit committee may serve on the audit committee of more
than two other publicly traded companies unless the board has first determined



 that such simultaneous service would not impair the ability of the member to serve effectively on the
audit committee. No current director or director nominee serves on more than four public company boards (excluding Hydro One) and no member of the audit committee serves on more than two public company boards. 

Board Interlocks 
 The board
seeks to avoid having more than one board interlock at any given time. A “board interlock” is a circumstance where two or more directors of the board serve on the board of directors of the same publicly-traded company (excluding in the
case of the company directors, Hydro One Inc.). Directors may not accept an invitation to join the board of another publicly-traded company, and new candidates for service on the board will not be invited to join the board, if it would result in
there being more than one board interlock (or would increase the number of directors involved in the same board interlock), in each case unless approved by the board. The company currently has one board interlock as set out below.

 Assessments 
 The
governance committee is responsible for overseeing the annual assessment of the effectiveness of the board as a whole, each board committee, the board chair, each committee chair and each individual director (having regard to the mandate of the
board and the mandate of the relevant committee, as the case may be). Peer assessments and self-evaluations are conducted at the individual director level. At the completion of the assessments, the governance



 committee reviews the annual board and committee performance evaluation process, makes
recommendations to the board, and reports to the board chair the results of both the annual assessment and performance evaluation process. The process includes the completion of written questionnaires and one-on-one meetings with the board chair to discuss individual performance and the effectiveness of the board and committees. The board and each committee also review their results each year and determine
objectives for the following year.

 Committee Reports 

The board has established four committees: (i) the audit committee; (ii) the governance committee; (iii) the health, safety,

 EXECUTIVE COMPENSATION 

I – Letter to Shareholders 

Dear fellow shareholders, 
 On behalf
of Hydro One’s human resources committee (the committee) and the board of directors, I am pleased to provide you with an overview of the key aspects of our executive compensation program and practices for 2017, as well as highlights of
the committee’s activities. 
 Executive Compensation Program Overview 

The company’s executive compensation program is designed to reinforce our pay for performance philosophy and align our executives’
interests with those of Hydro One’s shareholders and other stakeholders. While we continue to provide market competitive total compensation opportunities that enable us to attract, retain, motivate and reward highly qualified executives, our
focus is to ensure that our executives’ actual compensation is reflective of their contribution to Hydro One’s financial performance and overall success. 

The key components of the company’s compensation program remain largely unchanged from last year: 

 

	·	 	Base salary: Salary ranges based on peer comparator groups with individual base salary reflecting merit and potential. 


 

	·	 	Short Term Incentive Plan (STIP): The STIP rewards the achievement of annual company and individual performance goals. The STIP opportunity is expressed as a percentage of base salary and payouts
may range from 0% to 200% of target based on performance. Both the STIP opportunity and the weighting of company and individual goals are based on job category and are aligned with the relevant peer groups. STIP awards are subject to clawback under
certain conditions. 

  

	·	 	Long Term Incentive Plan (LTIP): The LTIP rewards long term value creation and encourages employee retention. The LTIP grants vest at the end of a
pre-determined period (time vesting in the form of restricted share units or RSUs) and a portion of each grant is subject to specific performance measures (performance vesting in the form of performance share
units or PSUs). At the time of grant, LTIP values are expressed as a percentage of base salary. The 2017 LTIP grants increased the weighting of PSUs to 60% from 50%; thereby, further increasing the performance focus of the incentive plans.
Executives are required to retain shares in accordance with share ownership guidelines. LTIP awards are subject to clawback under certain conditions. 

  

	·	 	Pension Plans: A defined contribution pension plan (DCPP), consistent with peer company comparators, for new externally hired management and non-union
employees. Management and non-union employees who were participants in the existing defined benefit pension plan (DBPP) prior to the 2016 introduction of the DCPP continue to be members of the DBPP. All of the
named executive officers discussed in the circular participate in the DCPP. 

 2017 Highlights 

The company delivered solid financial results for 2017 and achieved a number of important strategic objectives. 

As part of its growth strategy, in July 2017, Hydro One entered into a merger agreement to acquire 100% of the shares of Avista Corporation
(Avista), a market leading, highly regarded, fully regulated transmission, distribution and generation utility headquartered in Spokane, Washington. In November 2017, the acquisition was approved by the shareholders of Avista, with
approximately 79% of the outstanding shares of common stock entitled to vote on the proposal voting 98% in favour of the merger. A number of regulatory approvals are required before the transaction can be completed. 

2017 also saw Hydro One successfully delivering on its work programs, achieving approximately $89.5 Million in productivity savings and making
measurable strides in becoming advocates for our customers and improving customer satisfaction. 
 At the committee’s recommendation,
the board applied discretion in determining the final corporate scorecard result of 128.9% for the 2017 STIP. Specifically, the board agreed with management’s decision to reduce the health and safety achievement to zero given the tragic loss of
four members of the Hydro One team in late 2017. In addition, one-time costs related to the acquisition of Avista were excluded from the 2017 net income result as management will be held accountable for
delivering the net income expected from the acquisition in future years. These corporate scorecard results and specific achievements of the named executive officers (NEOs) are detailed in the compensation discussion and analysis
(CD&A) that follows. 
 With respect to the NEOs’ total direct compensation, the committee revisited the compensation peer
group for the President and CEO and Chief Financial Officer and the board approved an increase in their target total direct compensation to reflect performance since the initial public offering. Mr. Schmidt’s actual total direct
compensation for 2017 was approximately 108% of the blended target. This outcome reflects the strong results as measured by the corporate and individual scorecards, as well as Mr. Schmidt’s leadership of Hydro One’s transformation
over the past year. Further details are contained in the 2017 compensation profiles. 
 The committee also undertook a detailed review of
the long-term incentive awards for the NEOs in light of the board’s approval of the strategic roadmap in early 2017. Consistent with this long-term strategy, the board approved the inclusion of stock options as a component of the 2018 long-term
incentive awards for the President and CEO and his executive vice president level direct reports given that stock options offer a longer term view than other equity instruments.

 In addition to the 2017 accomplishments highlighted above, the company also made significant progress
on the following important priorities: 
 Talent Management – One of the key responsibilities of the committee is to ensure
that we have a robust talent pipeline, particularly for our leadership roles. In 2017, the committee oversaw further implementation of the company’s talent management program, including the development of comprehensive succession and
development plans. Managing the turnover of senior leaders as we continue our transformation from a government held entity to a publicly listed company is an important area of focus for the committee. 

Labour Relations – The committee regularly engaged in discussions with management on labour strategy and collective bargaining to ensure
that risks are being managed appropriately. 
 Diversity and Inclusion – We are deeply committed to diversity and inclusion. In
2017, we continued to dedicate significant resources and attention to improving the diversity of our workforce. While we continued to meet our diversity policy target of 40% female directors, Hydro One reached an important milestone of one-third women in senior leadership roles, hiring over 50% women into open executive roles during 2017. We are proud to support programs such as the Women in Trades, Technology and Engineering Network that
encourage young women to enter the workforce in non-traditional roles. Hydro One has also partnered with Men Advocating for Real Change (MARC) Leaders. MARC is aimed at promoting workplace inclusion and
advocating for women’s rights in areas of empowerment, accountability, courage and humility with the goal of creating real change. We will continue to focus on broadening the company’s activities beyond gender diversity. 

2018 Priorities 
 The management
team has been augmented with the addition of Mr. Paul Dobson as Chief Financial Officer and Mr. Patrick Meneley as EVP and Chief Corporate Development Officer in early 2018. Having filled these critical leadership roles, talent management
will remain a priority on the committee’s agenda with a focus on succession planning and accelerating the development of high potential employees. 

 

 While the organization has made considerable strides towards its diversity and inclusion objectives,
we will continue to actively monitor initiatives that further broaden and progress Hydro One’s commitment in this regard. The committee will also continue to oversee the advancement of the company’s labour relations strategy and bargaining
mandates, as well as pension plan performance. 
 With the anticipated close of Avista in the second half of 2018, the committee will be
reviewing executive compensation including compensation peer groups and performance measures that recognize Hydro One’s increased size and expansion into the United States (U.S.). We will also oversee the inclusion of U.S. employees into Hydro
One’s long-term incentive program. We will continue to monitor the overall effectiveness of the company’s compensation programs and practices to ensure they remain aligned with Hydro One’s strategic roadmap and stakeholder interests.

 Thank you for taking the time to read the following detailed CD&A. We trust it provides you with clear and relevant information
that allows you to understand and evaluate our executive compensation program and practices and to cast an informed ‘say on pay’ vote at the upcoming annual meeting of shareholders. We welcome any comments or questions you may have, and
invite you to submit them by email c/o the Corporate Secretary at CorporateSecretary@HydroOne.com. 
 Sincerely, 

 
 



 
 Ian Bourne 
 Chair of the Human Resources Committee

 ii. Compensation Practices at a Glance 

The table below highlights executive compensation practices we have implemented to drive performance and achieve shareholder value. 

 

					
			
	 ✓
	 	 WHAT HYDRO ONE DOES
	  	 



 WHAT HYDRO ONE DOES NOT DO

			
	✓	 	Pay for performance – aligns pay with both corporate and individual performance and uses several performance measures to avoid undue focus on any particular measure (see pages 52 and
62)	  	 



   Does not allow executives to hedge their holdings of common shares, PSUs or RSUs as it would undermine alignment with shareholder interests

	 	  	 



   No loans to executives

 Compensation Advisors 

The committee engaged a compensation advisor, Hugessen Consulting Inc., during 2017 to assist it in carrying out its mandate. All decisions and
actions taken by the human resources committee and the board have been based on numerous factors and considerations which may, but do not necessarily, reflect the information or advice provided by the advisor. 

Hugessen Consulting Inc. 
 Beginning in 2015, the human
resources committee retained Hugessen Consulting Inc. (Hugessen) as compensation advisors independent of management. Hugessen is an independent consulting firm that provides advice to boards and compensation committees on executive
compensation. In 2016 and 2017, Hugessen was retained to provide advice on the competitiveness and effectiveness of Hydro One’s compensation programs, including a review of the overall long-term incentive plan structure, and to provide updates
to the human resources committee on executive compensation best practices and evolving governance trends in both Canada and the United States.


 

  
 Hugessen’s fees (including
taxes) incurred during 2017 and 2016 regarding services provided to the committee are as follows:

 ii. Compensation Risk Management 

Hydro One’s compensation program is structured to provide an appropriate balance of risk and reward consistent with the company’s risk
profile and to ensure that compensation practices do not encourage excessive risk-taking by executives. Such risk mitigation practices include the following: 
  

 
  

			
	Pay Mix	  	The variable component of Hydro One’s compensation program (which includes both short term and long term incentives) represents a sufficient percentage of
“at-risk” compensation to motivate executives and other employees of the company to focus on both short term and long term results and performance criteria.
		
		  	All elements of compensation, together, ensure a balance in the mix of fixed and variable compensation, short term and long term incentives, cash versus equity, and performance-based versus time-based
awards.
		
	Capped Payouts	  	The maximum amount an executive can receive under the short term incentive plan is capped at 200% of target. Performance share units (PSUs) are also capped at 200% of target.
		
	 Effective Design of Long
  

Term Incentive Mix
	  	Long term incentives (currently PSUs and restricted share units (RSUs)) will vest over a specific vesting period, with both PSUs and RSUs vesting at the end of the period (with a three-year
performance term for PSUs).
		
		  	A combination of time-vesting and performance-vesting long term incentives and varied performance measures provide a balanced approach to driving performance, avoid undue risk-taking and align management
with long term shareholder interests.
		
	Clawbacks	  	Executives may be required to forfeit outstanding incentive awards and repay incentive compensation that have already been paid if, among other things, there is wrongdoing, misconduct, a material
misstatement of Hydro One’s financial results, an error in any financial or operating measure used to determine incentive compensation amounts, or as may be required by applicable laws, stock exchange rules or other regulatory requirements.
This applies to cash bonuses, the value of options, PSUs, RSUs and other equity-based compensation awards, whether vested or unvested, including those which have been paid or settled.
		
	 Share Ownership
  

Requirements
	  	To better align the interests of the company’s executives with the interests of Hydro One’s shareholders, the company has put in place share ownership
guidelines based on the level of the position. Under these guidelines, the company’s executives are subject to share ownership requirements which can be met through direct or beneficial ownership of the company’s common shares, management
deferred share units (management DSUs) and/or time-vested RSUs granted under the long term incentive plan. Individuals have until the later of five years from: (a) the closing date of the initial public offering of Hydro One’s
shares in November 2015; and (b) the date they first became subject to these requirements to satisfy the share ownership requirements. Employees who were subject to these requirements and are promoted or appointed into a position that is
subject to a higher share ownership requirement have three years from the date of their promotion or appointment to meet the higher minimum requirement. The executives must maintain such ownership post-retirement for 24 months (in the case of our
President and CEO and CFO) or 12 months (in the case of other executives).

	Anti-hedging	 	Directors, executives and other employees are prohibited from purchasing financial instruments that are designed to hedge, offset or otherwise reduce or limit their economic risk, including with respect to a
decrease in market value of equity securities of the company granted as compensation or held, directly or indirectly, by such individuals, or otherwise undermining their alignment with shareholder interests. Prohibited transactions include hedging
strategies, equity monetization transactions, transactions using short sales, put options, call options, exchange contracts, derivatives and other types of financial instruments (including, but not limited to, prepaid variable forward contracts,
equity swaps, collars and exchange funds), and the pledging of or granting of any other security interest in equity securities of the company as security for any loan where recourse is limited to the pledged security.	 			
			
	Trading Restrictions	 	Executives are prohibited from trading Hydro One securities during our trading blackout period.	 			
			
	Use of Discretion	 	 The human resources committee and/or the board can exercise discretion when making
compensation decisions to address exceptional circumstances not contemplated within the compensation plan design or performance measures.
  
	 	 	 	 


 

 iii. Say on Pay 

Hydro One strives to compensate its executives in a manner that is fair, competitive and linked to performance. The company endeavours to provide
executive compensation disclosure which satisfies all legal requirements, is aligned with best practices and is complete, clear and understandable. This is done in order to assist shareholders in forming a reasoned judgment about compensation
practices at Hydro One. 
 The board believes in shareholder engagement and offers shareholders the opportunity to make their views on the
company’s




 
approach to executive compensation known to the company. As such, Hydro One has adopted an annual say on pay advisory vote on executive compensation as part of its stakeholder engagement policy.
The directors of the corporation remain responsible for overseeing the company’s executive compensation practices and are not relieved of these responsibilities by a positive advisory vote by shareholders. 

At our annual meeting of shareholders held on May 4, 2017, 489,688,822 (or approximately 99.76%) of the votes cast approved
our overall approach to executive compensation. 

 


 

 C. Approach to Executive Compensation: 

i. Decision-Making Process to Determine Compensation 
 Hydro
One’s compensation decision-making process involves management, the human resources committee, advice from third-party 

 



 advisors, and the board for final approval. Outlined below is a general overview
of the process that the company follows in determining compensation. 

 

  

			
		 	  
 ·  Management recommends program design.

		
		 	
·  The human
resources committee reviews and recommends the program and performance measures to the board for review and approval to ensure compensation is arrived at on a corporate-wide basis.

		
		 	
·  The human
resources committee approves the compensation payable to the President and CEO’s direct reports who hold an executive vice president level position (including the named executive officers).

		
		 	
·  Board approves
the compensation payable to the President and CEO after receiving the human resources committee’s recommendation.

MANAGEMENT INFORMATION CIRCULAR HYDRO ONE LIMITED    TSX: H





                     









 1. Design of the compensation program 

Management designs the Hydro One compensation program. 
 Management presents its recommended compensation program to the human resources committee, which reviews the recommendations (with its independent advisor), and then the human resources committee provides its recommendations to the
board for approval. 
 Hydro One has successfully transitioned to a compensation program with significant variable “at risk”
compensation including a stronger performance-based short term incentive plan component and a long term incentive plan component aligned with being a publicly traded organization. In 2017, the committee undertook a detailed review of the long-term
incentive plan having regard to the company’s long term strategy and it approved the inclusion of stock options for certain executives for the grants to be made under the LTIP in 2018. The human resources committee continues to monitor the
compensation program to ensure it is achieving its intended results and may refine the program over time to ensure it continues to be aligned with the company’s strategy and long term objectives. 

Further details regarding the company’s short term incentive and long term incentive plans are provided on pages 61 and 63. 

2. Choice of performance measures and annual targets 

Management suggests objectives for the company and prepares corporate performance measures with their respective weightings for the incentive plans.

 The human resources committee reviews the corporate performance measures and related weightings proposed by management for the short
term incentive plan and the long term incentive plan and may accept them or suggest modifications. Once the human resources committee has completed its review, it recommends the corporate performance measures and related weightings to the board for
approval. 
 At the beginning of each year, the President and CEO reviews and sets the annual individual objectives and performance
measures designed to support the company’s strategy and which will be used to assess the individual performance of each of the President and CEO’s direct reports who hold an executive vice president level position (including the named
executive officers) for purposes of the STIP. 
 The human resources committee then reviews and approves the individual annual objectives
and performance measures, with adjustments as appropriate.




 
Similarly, at the beginning of the year, the human resources committee reviews and considers the President and CEO’s annual individual objectives and performance measures, may amend them,
and then recommends them to the board for approval. 
 3. Set targets for executive compensation 

With assistance from its independent advisor, the human resources committee develops and recommends target compensation and
variable pay for the direct reports of the President and CEO who hold executive vice president level positions, including the named executive officers identified on page 58, after reviewing the results of its benchmarking analysis (see page 60 for
information about our benchmarking analysis and compensation peer groups). For other executives, management develops and recommends target compensation and variable pay after reviewing compensation for similar roles and responsibilities within the
comparator peer group. The peer group used for benchmarking compensation is reviewed annually by the human resources committee. 
 4. Assess company performance 
 Early in the first quarter of every year, management assesses
company performance against the corporate performance measures approved by the board and presents its findings to the human resources committee. Management then makes recommendations on the results to the human resources committee. 

The human resources committee reviews management’s recommendations, together with input from its independent advisor,
considers whether adjustments are necessary or appropriate to reflect events occurring during the performance period that affect the applicable performance objective and recommends to the board for approval the degree to which corporate performance
measures for the incentive plans were met. 
 The board reviews the recommendations of the human resources committee
and approves the company performance results for compensation purposes. 
 5. Assess individual performance

 In reviewing the performance and compensation of his direct reports who hold an executive vice president level
position (including the named executive officers), the President and CEO: 
  

	·	 	assesses their performance against their annual objectives; and 	 

  

	·	 	recommends to the human resources committee their salary, short term incentive awards and long term incentive awards, taking into account past performance, previous awards, future potential and
market position.

 EXECUTIVE COMPENSATION 

 

 The human resources committee completes an in-depth
assessment of the President and CEO’s individual performance in leading the company towards its corporate goals and executing against Hydro One’s long term strategy, including: 

 

	·	 	overall company performance; 

  

	·	 	implementation of the President and CEO’s strategies to increase shareholder value; and 

  

	·	 	achievement of the President and CEO’s annual objectives. 

 6.
Award compensation 
 The human resources committee reviews, finalizes and approves the compensation, including base salary and
incentive awards of the President and CEO’s direct reports who hold an executive vice president level position (including the named executive officers).



 The President and CEO is not involved in determining his own compensation. The human resources
committee reviews the President and CEO’s self-assessment (and consults with its independent advisor) before considering his compensation. 
 The human resources committee’s independent advisor, if required, may provide an analysis for the human resources committee to review when making its decisions about President and CEO compensation. 

Following such review, the human resources committee recommends the compensation of the President and CEO to the board for approval.

 This CD&A pertains to Hydro One and its subsidiaries, including Hydro One Inc. 

 

 iii. Hydro One’s Approach to Compensation 

The following section discusses the compensation structure, programs and significant elements of compensation for the company’s NEOs.

 1. Benchmarking and Pay Positioning for Named Executive Officers 

The target total direct compensation for 2017 for all executives, including the NEOs, was set by the board, taking a range of factors into account,
including its stated compensation philosophy to be at or around the median of the relevant peer group as well as comparing executives’ compensation relative to each other. Actual compensation



 takes into consideration each individual’s performance as well as skills and experience as
benchmarked through an extensive executive search process. Each role requires a high level of skill and proven experience with large, complex publicly traded enterprises, either as an executive with, or an advisor to, such enterprises. For details
on the NEOs’ 2017 target total direct compensation and actual compensation, see their individual compensation profiles starting on page 70. 
 The company’s compensation philosophy is to provide total compensation opportunities that are competitive in the context of relevant peer groups for various management levels.

 Prior to the initial public offering, the company identified a primary reference group consisting of
the four largest utilities listed on the TSX plus four other TSX listed companies within the broader energy industry of comparable size and scope of operations to Hydro One. These eight companies are listed in the following table: 

Utility and Broader Energy Industry Compensation Peer Group 
  

			
		
	 Utility Peers
	 	Broader Energy Peers
		
	 AltaGas Ltd.
	 	ATCO Ltd.
		
	 Emera Incorporated
	 	Inter Pipeline Ltd.
		
	 Fortis Inc.
	 	Keyera Corp.
		
	 Pembina Pipeline Corporation
	 	TransAlta Corporation

 This utility and broader energy industry compensation peer group was used to determine the target total direct
compensation for the 


 President and CEO and Chief Financial Officer at the time of their hire in 2015
and for 2016. 
 For purposes of determining the 2017 compensation for Hydro One’s named executive officers, the
company used a primary reference group consisting of the following 19 Canadian-based entities, reporting in the heavy industrial sector, with a large unionized workforce, a
pay-for-performance culture, and many engineering/technologist job positions. This executive compensation peer group reflects the broader range of companies with which
Hydro One competes for talent and was originally adopted in 2016 for the NEOs, other than the President and CEO and Chief Financial Officer. Having completed two strong fiscal years since the IPO and given the status of our transformation, in 2017,
the company extended the use of this broader compensation peer group to the President and CEO and Chief Financial Officer positions.

 In selecting this compensation peer group, the company considered scoping criteria that are
reflective of the size, scale and complexity of Hydro One’s businesses, including revenues, assets, market capitalization and enterprise value. Companies were



 selected generally based on a range of approximately 0.5x to 

2.0x Hydro One’s positioning on the criteria set out in the chart on the next page at the time of selection.

 Notes: 
  

	1 	The existing registered DBPP for management and non-union employees which was originally established on December 31, 1999 by Hydro One Inc., the company’s wholly owned
subsidiary, was closed to new non-union employees effective September 30, 2015. The NEOs and other new non-union employees hired on or after July 1, 2015 who
were not eligible to join the DBPP as of September 30, 2015 participate in the DCPP effective January 1, 2016. Existing non-union employees who were eligible members of the DBPP as of
September 30, 2015 continue to participate in the existing DBPP. For further details on the existing DBPP, see “Defined Benefit Registered Pension Plan” starting on page 86. 


 

	2 	In 2015, the company also introduced share grant plans for qualifying union-represented employees. While these plans do not affect Hydro One’s executives (including the NEOs) or
non-union employees, they increase the alignment of eligible unionized employees in the success of Hydro One. In addition, the company also introduced a Society Represented Employee Share Ownership Plan
(Society ESOP Plan) to enable certain eligible employees that are represented by the Society of United Professionals (Society-represented employees) to acquire common shares of the company in a convenient and regular method through
payroll deduction. The eligible Society-represented employees are permitted to contribute a maximum of 4% of their base salary with a company match of 25%. The vesting period for the Society ESOP Plan is 2 years. In addition, the eligible
Society-represented employees can only participate in either the share grant plan or the Society ESOP Plan, but not both. 

 For
further details on these plans, see “Share Grant Plans for Certain Members of the Power Workers’ Union and the Society of United Professionals” starting on page 95. 

 

 3. About the Short Term Incentive Plan 

Hydro One’s short term incentive plan is designed to, among other things: 

 

	·	 	reward participants for achievement of annual corporate and individual performance goals, and 

  

	·	 	focus participants on the drivers of value creation.




 The company’s short term incentive plan is available to all full time non-union employees, including executives. Provided below is a summary of the components of the short term incentive plan.

 4. About the Long Term Incentive Plan 

Hydro One’s long term incentive plan is designed to, among other things: 

 

	·	 	reward executives for longer term value creation; 

  

	·	 	attract and retain highly qualified and experienced talent; and 

  

	·	 	foster alignment with shareholder interests.




 The company’s long term incentive plan was introduced in 2015 with the first
grants made in early 2016. It is available to executives and certain non-union employees of Hydro One and its subsidiaries as determined by the human resources committee.
Non-employee directors are not eligible to participate. Awards under the LTIP are expected to be settled in common shares from treasury. Provided below is a summary of the components of the LTIP as implemented
by the human resources committee in respect of specific grants under the LTIP in 2017. 

 

  
  

							
	  
 Types of Awards
	  	  
 PSUs: An award that entitles the
participant to receive common share(s) in the future subject to the achievement of specified performance criteria.

		
		  	RSUs: An award that entitles the participant to receive one common share in the future, subject to continued employment during the vesting period.
		
		  	In 2017, the allocation of PSUs for executives was increased to 60% of the long term incentive award and RSUs decreased to 40%. This resulted in a higher
at-risk element of compensation as it increases the proportion of incentives subject to performance measures. In 2016, this value was divided equally between PSUs and RSUs.
		
		  	While none of the following have been granted, the LTIP also allows for the grant of options, share appreciation rights, restricted shares, deferred share units and other share based awards at the
discretion of the human resources committee. At its December 8, 2017 meeting, the board approved the awarding of stock options to certain eligible employees commencing in 2018. The 2018 LTIP grant for these eligible employees (including NEOs)
will be comprised of 50% PSUs, 25% RSUs and 25% stock options.
		
	Vesting	  	Unless otherwise determined by the human resources committee:
		
		  	PSUs: Awards granted in 2017 vest at the end of the three year performance period (December 31, 2019), subject to a performance multiplier of 0 to 200% based on achievement of specific
performance measures.
		
		  	RSUs: Awards granted in 2017 vest on December 31, 2019 assuming the individual has remained employed by the company or its subsidiaries through such
date.
		
	Dividend Equivalents	  	Both PSUs and RSUs accrue dividend equivalents and are settled in common shares in accordance with the performance results and/or vesting requirement.
		
	Performance Measures	  	Three year average earnings per share (EPS): Each PSU granted in 2017 is subject to achieving certain performance thresholds for the three-year average EPS for the period from January 1,
2017 to December 31, 2019 (the performance period). In respect of the performance thresholds, below a certain performance threshold, no PSUs will vest. At the target performance threshold, the PSUs vest at the target level of 100% and will
entitle the holder to one common share for each PSU granted. At or above the maximum performance threshold, the PSUs vest at the maximum level of 200% and will entitle the holder to two common shares for each PSU granted. Between performance
thresholds, PSUs are earned on an interpolated basis.
		
		  	Dividend rate: If the average dividend rate for any rolling 12 months during the performance period falls below the annualized quarterly dividend rate at the time of grant, no PSUs will vest
regardless of whether the EPS performance thresholds are met.
		
		  	PSU Calculation:
		
		  	The above is summarized in the following illustration:
		  	




		  	 *  Actual payout results are subject to the board’s review of the
audited financial statements and approval of the payout percentage

 5.
Non-Union Employee Share Ownership Plan
  
 Hydro One strongly supports share ownership by its employees and, accordingly, offers an employee share ownership plan (ESOP) for non-union employees. The plan provides participants with the
opportunity to acquire common shares purchased on the market through payroll deduction. It is designed to:
  

·  promote an
ownership mentality amongst non-union employees;
	  	
·  align the
interests of non-union employees with shareholder interests; and
  

·  increase
employee awareness and interest in Hydro One performance.
  
 All
regular non-union employees not represented by a union who have completed at least six months of continuous service with the company or its subsidiaries prior to the date of enrollment in the plan are eligible
to participate. Provided below is a summary of the components of the non-union employee share ownership plan.



			
	  
  

Source of shares
	  	Shares are purchased on the market at prevailing prices (non-dilutive).
		
	 Employee contribution
	  	Up to 6% of base salary, through payroll deduction.
		
	 Employer match
	  	Hydro One matches 50% of the employee contribution up to a maximum of $25,000 per year.
		
	 Vesting
	  	All shares purchased with contributions vest immediately.
	
	 As at March 14, 2018, approximately 84% of eligible
non-union employees were enrolled in Hydro One’s non-union employee share ownership plan.

 


  
  

			
	 D. 2017 Performance Based Compensation Determination
  

i. 2017 Corporate Performance
  

Payouts under the STIP for 2017 were based on Hydro One’s performance against a balanced corporate scorecard. Hydro One’s balanced
corporate scorecard, established at the beginning of 2017, consisted of 5 corporate goals with 9 underlying performance measures and targets. In measuring the company’s performance against the targets, the human resources committee reviewed
management’s assessment of Hydro One’s performance
	  	 against each pre-established measure, and based on this and, using its informed judgment,
approved or modified (as appropriate) the ultimate score for each performance measure and the aggregate corporate score.
  

The following table sets out Hydro One’s corporate performance measures and results for 2017. Based on the company’s results, the human
resources committee recommended, and the board approved, an overall corporate performance multiplier equal to 128.9% of the target.

	(1) 	Actual achievement was 90% of target. In accordance with plan terms, Health and Safety achievement is reduced by 50% in the event of an employee death. However, due to the aviation accident in 2017, management reduced
this achievement to 0%. 

  

	(2) 	The Tx In Service Additions approved by the Ontario Energy Board (OEB) was $868 Million; actual results were within 0.5% of this approved amount and no adjustments were made to reflect this in the STIP results.

 EXECUTIVE COMPENSATION 

 

 In making this determination, the board approved management’s recommendation to reduce the
Health and Safety achievement to 0% as a result of the catastrophic aviation accident in 2017. The board also applied its discretion and excluded one-time acquisition costs related to the Avista transaction
from net income for purposes of the short-term incentive plan results. 
 As illustrated by the chart above, the company successfully
delivered on its financial and operating plans with key accomplishments including: 
  

	 	·	 	strong transmission reliability duration results as measured by the System Average Interruption Duration Index (SAIDI) primarily due to less defective equipment interruptions offset by distribution
reliability results below target due to storms in the latter half of 2017, 

  

	 	·	 	effective and disciplined management of key infrastructure investments (“in service additions”) within the OEB approved budget tolerance, 


 

	 	·	 	net income (normalized for Avista one-time acquisition costs) above target attributed to lower vegetation





	 	management costs, lower corporate common costs, lower volume of lines and stations maintenance work and lower depreciation and financing costs, all of which mitigated the lower transmission peak load and
distribution consumption driven by mild weather in the first half of 2017 and OEB disallowances of budgeted transmission revenue requirements, 

  

	 	·	 	productivity savings 27% above target largely driven by initiatives led by the Operations team such as
“move-to-mobile”, fleet and supply chain initiatives, and 

  

	 	·	 	significantly improved customer satisfaction results for transmission customers (7% above target) attributable to renewed commitment to customer advocacy and enhanced reporting for large customers.


 Individual performance which was considered in determining a portion of STIP payments to each NEO is summarized under

 ii. Share Performance 

 

 The following graph compares the total cumulative return of a shareholder who invested $100 in Hydro
One’s common shares from the closing of the company’s initial public offering on November 5, 2015 (using the initial public offering price of



 $20.50) to December 31, 2017, with that of the S&P/TSX Composite Index and S&P/TSX
Capped Utilities Index and the trend in total compensation awarded to our NEOs over the same period.(1) 

 

  
 Comparison of 26 Month Cumulative
Total Return 
 Assumes Initial Investment of $100 
  





 
 Note: 
  

	1 	Hydro One became a reporting issuer on October 29, 2015. The price of Hydro One’s common shares on closing of the initial public offering before markets opened on November 5, 2015 was the IPO price of
$20.50. This price is compared to the closing prices of the S&P/TSX Composite Index and S&P/TSX Capped Utilities Index on November 4, 2015. 


 

 The returns on Hydro One’s shares decreased in the last quarter of 2016 largely due to the
resulting impacts from the Ontario Energy Board’s reduction in allowed Return on Equity from 9.19% to 8.78% and the 10-year Canada bond yield increase from 0.95% to 1.81%. The company narrowly
underperformed the S&P/TSX Composite Index and the S&P/TSX Capped Utilities Index in the last quarter of 2017. The Province’s relatively large secondary sale of Hydro One shares in May 2017 had a negative impact on the share price. In
addition, we experienced a number of industry challenges that put downward pressure on share price performance: (i) lower regulated return on equity that impacted transmission and distribution revenues, (ii) extended unseasonably milder
weather reduced load volume and therefore revenue, (iii) the current rising interest rate environment, (iv) the uncertainty of regulatory approvals across multiple jurisdictions, related to the Avista transaction, and (v) an
unexpected Deferred Tax Asset decision by the Ontario Energy Board. That said, Hydro One materially moderated the impact of these headwinds in a



 disciplined approach focused on delivering value to shareholders and closed the
year with a very strong fourth quarter performance. 
 The 2016 and 2017 LTIP performance share unit awards are
strongly aligned with the organization’s performance through their three year average earnings per share performance measure. As a result, NEOs compensation which is heavily weighted to long-term incentives is closely aligned with that of
shareholders during the three year performance period. 
 The shareholder price and dividend growth do not accurately
reflect the value provided by the NEOs towards the company’s long-term strategy. While a portion of the compensation of the NEOs is performance-based, the continuing evolution of the company’s level
of maturity as a public company makes it difficult to correlate compensation to the trends shown in the above performance graph. The leadership team has made significant transformational changes in its evolution to a strong performing

 public company. The human resources committee has confidence that the President and CEO, along with
his executive team, will successfully lead the company to deliver on its long-term strategy and to generate sustainable value for the company and its shareholders. 

The committee and board have taken a longer-term view on management compensation. Specifically, providing
competitive compensation is critical to attract, retain and motivate the leadership talent required to deliver on Hydro One’s long term strategic plan and complex transformation. We believe the benefits of this



 investment will be realized by stakeholders over time. The committee is very cognizant of the need to
carefully monitor the compensation program and ensuring it is delivering its intended results. 
 While it is still relative early in the
transformation of Hydro One, during 2018, the committee will be considering the appropriateness of including performance measures such as relative total shareholder return or other specific relative performance measures within the long-term
incentive plan. 

 

  
 iii. Compensation Cost 

Compensation Cost of NEOs as % of Net Income 
 The following table shows the total compensation for the NEOs of the company for 2017, 2016 and 2015 as a proportion of net income of the company. 
  

													
				
	 	  	 	2017(2) 	 	  	 	2016	 	  	 	2015(1) 	 
				
	  
 Reported net
income ($000s)
	  	 	$682,000	 	  	 	$746,000	 	  	 	$713,000

($000s)
	  	 	$14,209	 	  	 	$11,714	 	  	 	$4,536	 
				
	 Cost of NEO compensation as a % of net income
	  	 	2.08%	 	  	 	1.57%	 	  	 	0.64%	 

 Notes 
  

	1 	The compensation cost for NEOs in 2015 was significantly lower due in part to compensation being pro-rated for Mr. Schmidt and Mr Vels for the length of their respective
service in that year. Compensation was also prorated in 2016 for Messrs. Kiraly, Pugliese and Scarlett reflecting their partial year of service in that year. 

  

	2 	The compensation cost for NEOs in 2017 includes the LTIP grant of $945,022 for Mr. Vels which was forfeited as he resigned on May 19th, 2017. 


It is important to note that as a result of the Ontario Energy Board’s decision issued in response to the company’s 2017-2018
transmission rate application, the amount of transformation-related compensation expenses recovered from ratepayers was adjusted to the 2015 pre-IPO amount, adjusted for inflation. These costs include
compensation for the board of directors and the executive vice president positions (including the NEOs). For these NEOs’ positions, the portion of compensation beyond the pre-IPO level is paid from the
earnings of the company and not recovered in rates.

December 31, 2016 and 595,287,586 common shares for the year ended December 31, 2017. 


	2 	In connection with the company’s initial public offering, rights to receive an aggregate of 5,412,354 common shares were granted to certain employees represented by the Power Workers’ Union and the Society of
United Professionals pursuant to two share grant plans. At December 31, 2016 rights to receive an aggregate of 5,334,415 common shares remained outstanding. At December 31, 2017 rights to receive an aggregate of 4,825,732 common shares
remained outstanding. For further details, see “ – Share Grant Plans for Certain Members of the Power Workers’ Union and the Society of United Professionals” starting on page 95. 


	3 	LTIP awards consisting of PSUs and RSUs granted in 2016 and outstanding at December 31, 2016 represent 484,750 common shares issuable (after giving effect to certain forfeitures), assuming all PSUs vest at 100% of
their target and all RSUs vest in full. LTIP awards consisting of PSUs and RSUs granted in 2017 represent 463,210 common shares issuable (after giving effect to certain forfeitures) and the total LTIP awards outstanding at December 31, 2017
represent 823,410 common shares issuable (after giving effect to certain forfeitures), assuming all PSUs vest at 100% of their target and all RSUs vest in full. The terms of the PSUs provide that depending on the achievement of certain performance
measures, they may vest at 200% of their target.

 2017 Performance 

Mr. Schmidt’s short-term incentive award was 128% of his target opportunity, which represents a corporate performance multiplier of 128.9%
(bearing an 80% weighting) and an individual performance multiplier of 124.3% (bearing a 20% weighting). This individual performance multiplier was based on the board’s assessment of Mr. Schmidt’s performance against his individual pre-defined scorecard. Mr. Schmidt reduced the health and safety components of the scorecards for all leaders to zero as a result of an aviation accident. 

Mr. Schmidt continued to lead the company through its transformation and in 2017 delivered numerous significant achievements. He was awarded
the 2017 Ontario Energy Association Leader of the Year Award. 
 In the first quarter of 2017, Mr. Schmidt led the development of a
board-approved corporate strategy which culminated in the company-wide launch of a Purpose statement, set of core values and new strategic direction. The corporate strategy is a roadmap to optimizing the core business and pursuing innovation,
diversification and disciplined growth. It prepares the company to meet evolving customer expectations and changing market dynamics in the utility industry. Safety continues to be the most important value in this organization and the company remains
committed to achieving a world-class safety record. The organization experienced a tragic event on December 14 and a number of electrical contact incidents in 2017. There is a deep commitment in the company towards a stated objective of a
journey to zero with the CEO’s personal engagement in every facet. The team is implementing strategies and procedures to effect cultural change across the organization.

 As detailed under the “Share Performance” section starting on page 67, with rising interest
rates and lower regulated return on equity that impacted transmission and distribution revenues, Hydro One, like many utilities, faced increasing pressure on its stock price. Hydro One’s Total Shareholder Return for 2017 was approximately -1%. Under Mr. Schmidt’s leadership, however, the company materially moderated the impact of these headwinds in a disciplined approach. Strong progress was achieved in executing against the corporate
strategy. Mr. Schmidt led the successful management of operational and cost efficiency initiatives that delivered approximately $89.5 Million in productivity savings in 2017 offsetting a weather related loss of income for three quarters which
returned to normal in the fourth quarter. Mr. Schmidt established the company as an industry leader in customer advocacy by working with his leadership team to launch the Winter Relief Program and by collaborating with the Province to develop
and carry out the Fair Hydro Plan and administering the Affordability Fund. He shaped a customer-centric culture that contributed to a 5% improvement over 2016 results in distribution customer satisfaction. Mr. Schmidt led the company through a
five-year incentive rate application for the distribution business and successfully announced the acquisition of Avista which, when approved, positions the company to achieve scale, an innovation platform, a leadership position in a growing region,
regulatory and asset diversification. Furthermore, Mr. Schmidt demonstrated a high level of personal engagement with key stakeholders including the Indigenous community leaders, provincial leadership, regulatory agencies, shareholders and the
financial community. In 2017, the organization experienced much improved relations with the Indigenous communities it serves with an expectation of a deep commitment for continued relationship building. The positive relationships Mr. Schmidt
and his leadership team built with Indigenous leadership resulted in signed memoranda of understanding with each of the Six Nations and the Mississaugas of the New Credit that will see joint ownership of the assets related to the Niagara
Reinforcement Project. 
 In 2017, Mr. Schmidt also focused on building a market leading team of professionals ensuring a strong fit
and complement for the company’s culture. In addition, Mr. Schmidt and his leadership team undertook a detailed succession planning and talent review designed to identify high potential and diverse future leaders. 

Actual Compensation – Mr. Schmidt’s total direct compensation was
increased on May 4, 2017 as described above. His actual compensation reflects this change, as well as his performance.

 Notes: 

	1 	Mr. Schmidt’s 2017 short term incentive award was calculated based on pro-rated salary amounts for the year. For 2016, Mr. Schmidt was granted a short term
incentive award of $1,170,000 representing a full year payout of 153% of his target opportunity. Mr. Schmidt elected to take 100% of his 2016 short term incentive award in management DSUs. 


 

	2 	In 2017, Mr. Schmidt was granted long term equity incentive awards with an aggregate value on the date of grant of $3,542,265 (subject to rounding) and said award was calculated based on pro-rated salary amounts for the year. These awards were granted in the form of 88,890 PSUs and 59,260 RSUs. Both PSUs and RSUs accrue dividend equivalents and are settled in common shares in accordance with the
performance results and/or vesting requirement. The amounts shown exclude dividend equivalent amounts earned on the PSUs and RSUs granted. In 2016, Mr. Schmidt was granted long term equity incentive awards with an aggregate value on the date of
grant of $2,379,948 consistent with the terms of his employment agreement (subject to rounding). These awards were granted in the form of 48,950 PSUs and 48,950 RSUs. The amounts shown exclude dividend equivalent amounts earned on the PSUs and RSUs
granted. The dividend equivalent amount for Mr. Schmidt in 2016 was $61,942. The dividend equivalent amount earned in 2017 for the PSUs and RSUs granted in both 2016 and 2017 (excluding management DSUs) was $179,269. 


 

	3 	Mr. Schmidt has until November 5, 2020 (five years from the closing date of the initial public offering of Hydro One’s shares) to meet the share ownership requirements. 


 

	4 	Values are based on the acquisition cost per share of the common shares on the date of purchase, the original grant value (for PSUs, RSUs and management DSUs), dividend equivalents earned to date and assumes the PSUs
vest at 100% of their target and the RSUs vest in full. Management DSUs are fully vested and accrue dividend equivalents when dividends are paid on the common shares and are redeemable for cash at the then prevailing market price of the common
shares upon settlement after the NEO ceases to be employed. The value of management DSUs for Mr. Schmidt was calculated on the grant date by dividing (a) the amount of his annual incentive payout (less any pension contributions) to be paid
in management DSUs by (b) the market price of our common shares, with fractions computed to three decimal places (decimal places are not shown). In 2017, Mr. Schmidt earned $32,396 in dividend equivalents on his 2016 management DSUs.


  

	5 	For purposes of the share ownership requirements, value is calculated using the original grant value (for RSUs and the acquisition cost (for common shares and management DSUs). Based on the $22.40 share price as at
December 29, 2017, the total value is $4,021,673 which represents a 3.35 multiple of base salary. 

  

	6 	PSUs are not included in calculating compliance with the share ownership requirements.

 EXECUTIVE COMPENSATION 

Chief Operating Officer 
  

			
	Gregory Kiraly, 53	  	Effective September 12, 2016, Gregory Kiraly was appointed to the role of Chief Operating Officer (COO) of Hydro One.
		
	 




 Chief Operating Officer

Toronto, Ontario, Canada
	  	 Prior to joining Hydro One in 2016, Mr. Kiraly served as senior vice president of Electric Transmission and
Distribution at Pacific Gas and Electric Company (PG&E) in San Francisco, which delivers safe and reliable energy to more than 16 million customers in northern and central California. Since joining PG&E in 2008, Mr. Kiraly led
efforts that achieved the lowest employee injury rates ever, seven straight years of record electric reliability, and over $500 Million in productivity improvements and efficiency savings. Before PG&E, Mr. Kiraly held executive-level
positions in energy delivery at Commonwealth Edison (Exelon) in Chicago and leadership positions in both gas and electric distribution at Public Service Electric and Gas Company in Newark, New Jersey.

 
 Mr. Kiraly holds a bachelor’s degree in industrial engineering
from New Jersey Institute of Technology and a master’s of business administration in finance from Seton Hall University. He is also a graduate of Harvard University’s Advanced Management Program.

	  

  
 



 
  

			
	 2017 Target Total Direct Compensation –

 

	Mr. Kiraly’s target total direct compensation has remained unchanged since his date of hire in 2016.
		
	 Base Salary
	  	$550,000
		
	 Short Term Incentive
	  	$385,000 (70% of base salary)
		
	 Long Term Incentive
	  	$1,072,500 (195% of base salary)
		
	 Target Total Direct
Compensation
	  	$2,007,500

 2017 Performance 
 Mr. Kiraly’s short-term incentive award was 129.9% of his target opportunity, which represents a corporate performance multiplier of 128.9% (bearing an 80% weighting) and an individual performance multiplier of 134%
(bearing a 20% weighting). As with Mr. Schmidt, Mr. Kiraly’s individual results reflect management’s decision to reduce the health and safety component of his individual scorecard to zero due to the aviation accident. 

As Chief Operating Officer, Mr. Kiraly oversees the complete transmission and distribution value chain including Planning, Engineering,
Construction, Operations, Maintenance, and Forestry; Shared Services functions including Facilities, Real Estate, Fleet, and Procurement; and the Telecom and Remote Communities subsidiaries. Mr. Kiraly is leading the operational transformation
of Hydro One with a focus on “operational excellence” and a renewed commitment to providing safe, reliable, and affordable power to its customers. During his first full year as Chief Operating Officer, Mr. Kiraly has restructured the
operations organization and re-staffed his executive leadership team. A new operating model has been developed and implemented, with a comprehensive leadership and governance structure that drives
accountability for significantly improved results. With the tragic aviation accident in the last month of the year and a number of electrical contact incidents preceding it, Mr. Kiraly and his team are focused on achieving world-class safety
performance through an integrated approach of the application of safety management system principles and employee engagement. 
 In 2017,
Mr. Kiraly and his team continued to refine and execute comprehensive process changes that reflect best practices regarding capital work execution. The process changes included advanced project engineering and design; a new cost estimating
system; a stage gate approval process; and an investment planning process that includes a comprehensive risk assessment process which results in a more objective, fact-based assessment of capital investment alternatives and capital allocation. These
process changes have resulted in a reduction of variability in project over/under runs and has produced two successive years of “on target” execution of the transmission capital work portfolio of just under $1 Billion annually.

 Mr. Kiraly and his team drove major operational improvements resulting in approximately $78.9
Million of the $89.5 Million corporate-wide productivity savings achieved in 2017. In addition, Mr. Kiraly’s team contributed to meaningful operating and capital cost reductions. Major technology projects have been implemented including a
new field mobility platform that automates the scheduling, dispatch and general work management producing $15 Million in annual savings and the installation of a telematics system on 5,000 fleet vehicles has resulted in a 10% reduction in fleet
vehicles and equipment. Mr. Kiraly is also overseeing the development of a Grid Modernization strategy and plan that will maintain transmission reliability as top quartile, dramatically improve distribution reliability, enable technology, and
provide greater customer choice. In order to address the impacts caused by multiple storms in the last half of the year and the ongoing need to improve distribution system reliability, Mr. Kiraly and his team developed and began implementation

Hydro One’s transmission customers increased to 87% overall which represents a 10% improvement over 2016 results. The contact centre received 2.5 million calls in 2017, of which 82% were answered within 30 seconds. Furthermore, overall

 Notes: 

	1 	Base salaries presented are actual amounts earned for fiscal years 2015, 2016 and 2017, as applicable. For the NEOs, they represent pro-rated amounts of their respective annual
base salaries for 2015 or 2016, as applicable, depending on the year they joined the company: Mr. Schmidt – $850,000 (2015), Mr. Vels – $500,000 (2015), Mr. Gregory Kiraly – $550,000 (2016), Mr. Ferio Pugliese
– $525,000 (2016), Mr. James Scarlett – $500,000 (2016), and Mr. Chris Lopez – $300,000 (2016). For 2017, the annual base salaries represent the pro-rated amounts for Mr. Schmidt,
with a salary of $850,000 from January 1, 2017 to May 3, 2017 and a salary of $1,200,000 from May 4, 2017 to December 31, 2017 and Mr. Lopez with a salary of $300,000 from January 1, 2017 to March 31, 2017 and a
salary of $313,500 from April 1, 2017 to December 31, 2017. 


	2 	None of the NEOs are entitled to perquisites or other personal benefits which, in the aggregate, are worth more than $50,000 or 10% of their annualized base salary for each of 2015, 2016 and 2017. 


	3 	Each NEO is eligible to receive an annual LTIP award consistent with market practices and quantum for comparative companies as defined by the board. The mix of instruments which will comprise the LTIP award will be
determined annually and may vary from year to year at the board’s discretion. In 2016, each NEO other than Mr. Lopez was eligible to receive an LTIP award as a percentage of base salary divided equally between PSUs and RSUs (the PSUs and
RSUs collectively referred to as the “Awards”). In 2017, PSUs and RSUs represented 60% and 40% of the LTIP award respectively. The number of PSUs and RSUs granted pursuant to the Awards were determined by reference to the closing price of
the common shares of the company on the grant date of the Awards. For Mr. Schmidt, the 2017 LTIP award was 280% of pro-rated base salary from January 1, 2017 to May 3, 2017 and 330% of pro-rated base salary from May 4, 2017 to December 31, 2017). Both PSUs and RSUs accrue dividend equivalents and are settled in common shares in accordance with the performance results and/or vesting
requirement. The amounts shown exclude dividend equivalent amounts earned on the PSUs, RSUs and management DSUs, as applicable. The dividend equivalent amounts for the NEOs in 2016 and 2017 were as follows: Mr. Schmidt – $61,942 (2016),
$179,269 (2017); Mr. Vels – $18,221 (2016), $6,205 (2017); Mr. Lopez – $0 (2016), $7,009 (2017); Mr. Kiraly – $9,690 (2016), $66,861 (2017); Mr. Pugliese – $21,180 (2016), $94,887 (2017); Mr. Scarlett
– $8,128 (2016), $55,572 (2017).

	4 	The dollar amounts represent the fair value of the awards on the grant date determined as a percentage of base salary (subject to rounding). The fair value of the PSUs and RSUs was determined by multiplying the number
of units granted by the closing price of the common shares on the date of grant. As noted, the value of the awards is determined as a percentage of base salary, which is established based on benchmarking data. In 2016, the awards were an equal
allocation of PSUs and RSUs. In 2017, PSUs and RSUs represented 60% and 40% of the LTIP award respectively. 

  

	5 	The short term incentive awards are attributed to the noted financial year, are based on a percentage of base salary and are paid by April 1 of the following year. Executives can elect to receive up to 100% of the
short term incentive awards in management DSUs. For Mr. Schmidt and Mr. Lopez, their 2017 LTIP award was calculated based on pro-rated salary amounts for the year. In 2017, Mr. Lopez and
Mr. Scarlett elected to take 100% of their short term incentive award in management DSUs. In 2016, Mr. Schmidt elected to take 100% of his short term incentive award in management DSUs. Mr. Pugliese, Mr. Kiraly, Mr. Scarlett
and Mr. Lopez were not eligible to make such an election in 2016. Each NEO, other than Messrs. Schmidt and Vels, were granted a short term incentive award pro-rated for the length of his service in 2016.


  

	6 	In recognition of the forfeited short-term incentive plan payment as a result of his departure from his former employer, Mr. Pugliese received a one-time attraction incentive
payment to reflect the pro-rated portion of the bonus earned at target at his previous employer. This payment was made at the same time the Hydro One 2016 STIP payment was processed in early 2017.


  

	7 	In recognition of the estimated LTIP value forfeited from his previous employer, Mr. Pugliese received the following attraction incentive equity awards: 


 

	 	•	 	a one-time award of 2016 PSUs equivalent to $699,901 (subject to rounding) with vesting at December 31, 2018 (performance period: January 1, 2016 to December 31,
2018) and contingent on the standard terms and conditions of the 2016 PSUs, including earnings per share relative to the performance targets and maintenance of the annualized dividend rate at a minimum level; and 


 

	 	•	 	a one-time award of 2016 RSUs equivalent to $699,901 (subject to rounding) with vesting as follows: 50% vested May 2017 (13,825 shares (including dividend equivalents) with a
value on vesting of $329,948) and 50% vest May 2018. 

  

	 	Both PSUs and RSUs accrue dividend equivalents and are settled in common shares in accordance with the performance results and/or vesting requirement. The above dollar amounts exclude dividend equivalents.


  

	8 	For 2015 only, in place of his long term incentive, Mr. Schmidt received a cash payment in respect of his target long term incentive award of 280% of base salary and a payment in respect of his target short term
incentive award of 90% of base salary, in each case pro-rated from his September 3, 2015 start date. 

  

	9 	For 2015 only, in place of his long term incentive, Mr. Vels received a cash payment in respect of his target long term incentive award of 140% of base salary and a payment in respect of his target short term
incentive award of 60% of base salary, in each case pro-rated from his July 1, 2015 start date. 

  

	10 	Messrs. Schmidt and Vels did not participate in the Hydro One DBPP in 2015. In lieu of the contribution to the Hydro One DCPP, Messrs. Schmidt and Vels received a cash payment representing the contribution Hydro One
would otherwise have made to the DCPP. This cash payment was $37,956 for Mr. Schmidt and $34,269 for Mr. Vels and is included under “All other compensation”. 


 

	11 	For Messrs. Schmidt and Vels, the amounts in 2016 include after tax dollars moved to a registered retirement savings plan for their benefit. 


 

	12.	Following Mr. Vels resignation on May 19, 2017, Mr. Lopez has acted in the capacity of CFO. Mr. Lopez’s base salary of $300,000 as at December 31, 2016 was increased to $313,500 on
April 1, 2017. Mr. Lopez did not receive any long term incentive for 2016. 

  

	13.	All NEOs, except Mr. Kiraly, participate in the non-union ESOP. Amounts include the employer contribution to ESOP on behalf of the NEO. For Mr. Schmidt and
Mr. Vels, the amounts in this column for 2017 represent the company’s contributions to the ESOP made in 2017 as well as a contribution made in respect of December 2016 but settled in January 2017. 


 

	14 	Following Mr. Vels resignation on May 19, 2017, his long term incentive awards from 2016 and 2017 and his short term incentive award for 2017 were forfeited. 


Outstanding Share-Based Awards and Option-Based Awards 

The following chart provides details regarding outstanding option and share-based awards for the NEOs as of December 31, 2017 (based on the
acquisition cost and dividend equivalents earned up to December 31, 2017) except with respect to management DSUs granted in 2018 to Mr. Lopez and Mr. Scarlett in respect of 2017 STIP:

 EXECUTIVE COMPENSATION 

 

 ii. Defined Benefit Registered Pension Plan 

Hydro One Inc., the company’s wholly owned subsidiary, established a contributory defined benefit registered pension plan (DBPP) on
December 31, 1999. Hydro One Inc. manages and invests the assets and liabilities of the pension fund as plan sponsor and administrator of the plan. Hydro One Inc. has closed participation in the Hydro One DBPP to new non-union hires effective September 30, 2015. Non-union employees who were eligible members of the DBPP as of September 30, 2015 continue to participate in the DBPP.

 The DBPP provides a benefit, in respect of all years of service, which is based on each plan member’s highest average earnings at
the time of his or her termination or retirement. The value of the increase or decrease in the present value of the defined benefit obligation is affected by differences between actual compensation for the year and the earnings increase assumptions
for the year, assumed at the end of the prior year. When the actual earnings increase is not in line with the assumed level, it impacts the total defined benefit obligation in respect of past service. If the expected highest average earnings




 
based on the most recent information is lower than the highest average earnings based on the prior year estimate, it results in a decrease in the defined benefit obligation. 

None of the current NEOs participate in the Hydro One DBPP. The NEOs and other new non-union employees
hired on or after July 1, 2015 who were not eligible to join the DBPP as of September 30, 2015 participate in the DCPP effective January 1, 2016. 

iii. DBPP Supplementary Pension Plan Benefits 
 Hydro One’s supplementary pension plan (the supplementary pension plan) provides benefits that are in excess of Income Tax Act (Canada) limits and that cannot be provided under the DBPP. The supplementary pension
plan is unfunded and the benefits from this plan are paid from general revenues. Hydro One Inc.’s obligations to participants under the supplementary pension plan are secured by a letter of credit. 

None of the current NEOs participate in the supplementary pension plan.

 Notes: 
  

	1 	The President and CEO and the CFO may voluntarily resign their employment at any time by giving the board 6 months’ written notice, while the other NEOs must give the board 3 months written notice.



	2 	An executive is considered to have ‘retired’ if the executive has given six months prior notice with the approval of the board, complies with such conditions as the board may require in connection with its
approval and as may be reasonably required to facilitate transitional matters and is paid no cash severance payment or retirement allowance or equivalent. If these criteria are not satisfied, the termination of employment will be treated as a
resignation, and the appropriate termination provisions will apply. 


	3 	Payment of such amounts are conditional upon delivery of a full and final release document to the company and compliance with post-employment covenants respecting any applicable
non-competition, non-solicitation and non-disparagement and maintaining the confidentiality of Hydro One’s confidential
information. 


	4 	Treatment only applies to termination by the company without cause or by the executive with good reason within 24 months following a change in control and only applies to awards made prior to the change in control.
There is no entitlement to any benefit upon a change in control without a termination of employment. “Good reason” means a material change in title, responsibilities or authority or a material reduction in base salary or in short term and
long term incentive opportunity.

	5 	A ‘change in control’ will occur in the following circumstances: 

  

	 	(a)	more than 50% of the outstanding voting securities of the company are acquired; 


	 	(b)	all or substantially all of the assets of the company are sold, assigned or transferred other than to a wholly owned subsidiary; 


	 	(c)	an acquisition of the company via merger, amalgamation, consolidation, statutory arrangement or otherwise or the dissolution or liquidation of the company; 


	 	(d)	individuals who at the beginning of any two-year period constitute the board cease to constitute a majority of the board during such
two-year period excluding any individuals whose service ceased due to death; 


	 	(e)	pursuant to its rights in the governance agreement, the Province of Ontario replaces the entire Board (other than the CEO) and, in its discretion, the Chair of the Board; 


	 	(f)	a change is made to an Ontario law or regulation that: 


	 	(i)	both (A) expressly states that it applies either (1) to Hydro One or an affiliate or (2) companies in the electrical transmission and/or distribution business generally but has a disproportionate effect on
Hydro One and its affiliates as a whole, and (B) would materially adversely affect the ability of Hydro One to achieve any corporate performance measures set out in any outstanding awards; or 


	 	(ii)	imposes limits on the quantum of compensation that may be paid to non-union employees of Hydro One or its affiliates other than restrictions established for rate approval or other
purposes which do not restrict amounts actually paid; or 


	 	(g)	the board passes a resolution confirming that a change in control has occurred. 

 As a result of
limitations on the ownership of the company’s shares under the Electricity Act (Ontario), there would have to be an amendment to such statute for a change in control to occur in
certain circumstances. Subparagraphs (d) to (f) above and paragraph 6(ii) below represent amendments to the LTIP that were approved by the board on November 10, 2017 and confirmed by the TSX on December 28, 2017. 

	6 	If within 24 months following a change in control, the executive’s employment is terminated by the company without cause then, without any action by the plan administrator: 


	 	(i)	if the change in control is one of the circumstances set out in paragraphs (a) to (c) or (g) of the definition of change in control, noted in footnote (5) above, the prior awards held by the executive on
the change in control (the “Affected Awards”) shall continue to vest and be settled or exercised in accordance with their terms; and 


	 	(ii)	if the change in control is one of the circumstances set out in paragraphs (d) to (f) of the definition of change in control noted in footnote (5) above, the Affected Awards shall vest and become realizable or
payable as of the termination date, and for this purpose any performance goals assigned to any such Affected Awards shall be deemed to have been met at 100% of the specified target level of performance for such performance goals and each such
Affected Award that is an option or share appreciation right shall continue to be exercisable until, and will expire on, the earlier of its expiry date and 90 days following the termination date. 


	7 	Mr. Lopez is entitled to 1 x aggregate of base salary plus lower of (i) average annual bonus for the prior 3 years and (ii) target bonus for the year of termination provided that if Mr. Lopez has not
worked 3 full calendar years at termination, Mr. Lopez will only be entitled to (ii). Mr. Lopez’s group health and welfare will continue for 12 months. 


	8 	Not applicable to Mr. Lopez.

 ii. Long Term Incentive Plan 
 A summary of the key terms of the LTIP are presented below: 
  

 
  

					
	Types of Awards	  	PSUs and RSUs. (See pages 61 and 63 for details)
		
		  	Restricted shares. A restricted share award is an award of common shares subject to forfeiture restrictions.
		
		  	DSUs. A DSU is an award that entitles the participant to receive common shares following termination of employment or service with the company. DSUs may be subject to performance
conditions or other vesting conditions.
		
		  	While none of the following have been granted, the LTIP also contemplates the possibility of grants of:
		
		  	Options. An option is the right to acquire a common share on a future date on payment of the exercise price. The exercise price of an option may not be less than the fair market value of a
common share on the date of grant. The term of an option may not exceed 10 years, unless extended due to the existence of a company trading blackout period. The human resources committee has not granted any option-based awards in 2017, however, on
December 8, 2017, the board approved that option-based awards will be awarded to eligible employees in 2018.
		
		  	SARs. A share appreciation right (SAR) is the right to receive common shares equal in value to the appreciation in the value of a common share over a period. The base price against which a
SAR is to be measured may not be less than the fair market value of a common share on the date of grant. An option and a SAR may be granted in tandem, in which event the SAR will vest and be exercisable on the same dates as the related option and
the exercise of the option results in the surrender of the SAR, and vice versa. The term of a SAR may not exceed 10 years, unless extended due to the existence of a company trading blackout period.
		
		  	Other awards. Other awards are awards that are convertible into or otherwise based on the common shares.
		
	Eligibility	  	Employees and consultants of Hydro One and its affiliates as determined by the human resources committee.
		
		  	Non-employee directors on the board are not eligible.
		
	Maximum No. of Shares Authorized	  	11,900,000 common shares or approximately 2% of the issued and outstanding shares. Within that limit the maximum number of common shares which may be issued as PSUs, RSUs or DSUs is 4,760,000
common shares (or approximately 0.8% of the issued and outstanding shares as of December 31, 2017).
		
		  	If an award expires without exercise, is cancelled, forfeited or terminated or otherwise is settled without the issuance of common shares, common shares which were issuable under the award will
be available for future grants. Common shares issued under awards of an acquired company that are converted, replaced or adjusted in connection with the acquisition will not reduce the number of shares available for awards under the LTIP unless
otherwise required by law or stock exchange rule.
		
	Insider Limits	  	Under the LTIP and any other Hydro One security based compensation arrangements:
		
		  	
·  maximum number
of common shares issuable to insiders at any time is 10% of the outstanding common shares.

		
		  	
·  maximum number
of common shares issuable to insiders within any one year period is 10% of the outstanding common shares.

		
	Company trading blackout periods	  	 If an award is scheduled to expire during, or within five business days
after, a company trading blackout period restricting employees from trading in common shares, then the award shall expire ten business days after such restricted trading period expires.

	Death & Disability	  	Unless otherwise determined by the human resources committee, a pro rata portion of the next instalment of the award due to vest shall immediately vest, based on the number of days elapsed since the last
instalment vested compared to the period from the last vesting date to the next vesting date (or if none have vested, the date of grant). Any performance targets are deemed to have been met at 100% of the target performance level. Vested awards
subject to exercise will remain exercisable for 90 days, or the award’s normal expiration date if earlier.
		
	Retirement	  	Unless otherwise determined by the human resources committee, all unvested awards continue to vest and are settled and exercised in accordance with their terms.
		
		  	“Retirement” means:
		
		  	 (a)  If the employee:

		
		  	 i.   is the CEO or reports directly to the CEO, the retirement has
been approved by the board and the employee complies with such conditions as the board may require, and

		
		  	 ii.  is not i above, the employee has reached age 65 or reached age 55
with a minimum of 10 years of service or such lesser age and/or service thresholds as the human resources committee may determine;

		
		  	 (b)  the employee has given formal notice of their intention to retire
six months in advance or such lesser period as the human resources committee may approve;

		
		  	 (c)   no cash severance payment or retirement allowance or
equivalent is paid; and

		
		  	 (d)  the employee has complied with such transitional activities as may
be reasonably required by Hydro One until the date the individual has ceased active employment.

		
	Resignation	  	Unless otherwise determined by the human resources committee, all unvested awards are forfeited. Vested awards subject to exercise will remain exercisable for 90 days, or the award’s normal expiration
date if earlier.
		
	Termination For Cause	  	All awards, whether vested or unvested, are forfeited and cancelled.
		
	Termination Without Cause	  	Unless otherwise determined by the human resources committee and except if termination occurs within 24 months following a change in control, all unvested awards are forfeited. Vested awards subject to
exercise will remain exercisable for 90 days, or the award’s normal expiration date if earlier.
		
	Termination Without Cause Within 24 Months Following	  	If within 24 months following a change in control, the executive’s employment is terminated by the company without cause then, without any action by the plan administrator:
	a Change in Control	  	  

(i)  if the change in control is one of the circumstances set out in paragraphs (a) to (c)
or (g) of the definition of change in control, noted in footnote (5) to the Termination and Change of Control Benefits table above, the Affected Awards (as defined in footnote (6) to the Termination and Change of Control Benefits
table above) shall continue to vest and be settled or exercised in accordance with their terms; and

		
	 	  	 (ii)   if the change in
control is one of the circumstances set out in paragraphs (d) to (f) of the definition of change in control noted in footnote (5) to the Termination and Change of Control Benefits table above, 1) the Affected Awards shall vest and become
exercisable, realizable or payable as of the termination date, 2) any performance goals assigned to any such Affected Awards shall be deemed to have been met at 100% of the specified target level of performance for such performance goals and 3) any
Affected Award that is an Option or SAR shall continue to be exercisable until, and will expire on, the earlier of its expiry date and 90 days following the termination date.

	Change in Control	  	The human resources committee may provide for the conversion or exchange of outstanding awards for new awards or other securities of substantially equivalent value (or greater value) in any entity
participating in or resulting from the change in control, or, for the accelerated vesting or delivery of shares under awards, or for a cash-out of outstanding awards.
		
	Definition of Change in Control	  	Subject to certain exceptions, means:
		
		  	 (a)  more than 50% of the outstanding voting securities of the company
are acquired;

		
		  	 (b)  all or substantially all of the assets of the company are sold,
assigned or transferred, other than to a wholly owned subsidiary;

		
		  	 (c)   an acquisition of the company via merger, amalgamation,
consolidation, statutory arrangement or otherwise or the dissolution or liquidation of the company;

		
		  	 (d)  individuals who at the beginning of any two-year period constitute the Board cease to constitute a majority of the Board, excluding any individuals whose service ceased due to death during such two-year
period;(1) 

		
		  	 (e)  pursuant to its rights in the governance agreement, the Province of
Ontario replaces the entire board (other than the CEO) and, in its discretion, the Chair of the board;(1) 

		
		  	 (f) a change is made to an Ontario law or regulation
that:

		
		  	 (i)  both (A) expressly states that it applies either (1) to
Hydro One or an affiliate or (2) companies in the electrical transmission and/or distribution business generally but has a disproportionate effect on Hydro One and its affiliates as a whole, and (B) would materially adversely affect the
ability of Hydro One to achieve any corporate performance measures set out in any outstanding awards; or

		
		  	 (ii)   imposes limits on the quantum of compensation that may be
paid to non-union employees of Hydro One or its affiliates other than restrictions established for rate approval or other purposes which do not restrict amounts actually paid; (1) or

		
		  	 (g)  the board passes a resolution confirming that a change in control
has occurred.

		
		  	As a result of limitations on the ownership of the company’s shares under the Electricity Act (Ontario), there would have to be an amendment to such statute for a change in control to occur in certain
circumstances. Subparagraphs (d) to (f) above and paragraph 6(ii) below represent amendments to the LTIP that were approved by the board on November 10, 2017 and confirmed by the TSX on December 28, 2017.
		
	Assignability	  	Options are generally not assignable or transferable. Other awards may be assigned to a ‘permitted assign’ (as defined under Canadian securities law), which includes a spouse, registered retirement
savings plan, registered retirement income fund or personal holding company.
		
	Discretion	  	The human resources committee can accelerate vesting or exercisability of an award. The human resources committee may adjust performance objectives in an objectively determinable manner to reflect events
occurring during the performance period that affect the applicable performance objective.
		
	Clawback	  	The human resources committee may provide that an award may be subject to potential cancellation, recoupment, rescission, payback or other action in accordance with the terms of any clawback, recoupment or
similar policy adopted by the company or as otherwise required by law or applicable stock exchange listing standards.
		
	Adjustments	  	 The human resources committee may make adjustments as it determines in its sole
discretion to the terms of any award, the number and type of securities issuable under the award and the number of common shares issuable under the LTIP in the event of a subdivision or consolidation of common shares or any similar capital
reorganization, or a payment of a stock dividend (other than a stock dividend that is in lieu of a cash dividend), or in the event of an amalgamation, combination, arrangement, merger or other transaction or reorganization of the company that does
not constitute a change in control.
