Principal Documents



The following documents, filed as Exhibits 99.1 through 99.2
hereto, are hereby incorporated by reference into this Annual Report on Form 40-F:



| | (a) | Annual Information Form for the fiscal year ended December 31,
        2011;

| | (b) | Management’s Discussion and Analysis of Financial Results
        for the fiscal year ended December 31, 2011 (included in the registrant’s 2011 Annual Report attached hereto as Exhibit
        99.2); and
| | (c) | Consolidated Financial Statements for the fiscal year ended December 31, 2011 (included in the registrant’s 2011 Annual Report attached hereto as Exhibit 99.2).                                            



ADDITIONAL DISCLOSURE

Certifications and Disclosure Regarding Controls and Procedures



|(a) | Certifications. See Exhibits 99.3 to 99.6 to this
        Annual Report on Form 40-F.
|--- | -------------------------------------------------------------------------------------
|(b) | Disclosure Controls and Procedures.                                                  



As of the end of the registrant’s fiscal year
ended December 31, 2011, an evaluation of the effectiveness of the registrant’s “disclosure controls and procedures”
(as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”)) was carried out by the registrant’s principal executive officer and principal financial officer. Based upon
that evaluation, the registrant’s principal executive officer and principal financial officer have concluded that as of the
end of that fiscal year the registrant’s disclosure controls and procedures were effective to ensure that information required
to be disclosed by the registrant in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized
and reported within the time periods specified in Securities and Exchange Commission rules and forms and (ii) accumulated and communicated
to the registrant’s management, including its principal executive officer and principal financial officer, to allow timely
decisions regarding required disclosure.



It should be noted that while the registrant’s
principal executive officer and principal financial officer believe that the registrant’s disclosure controls and procedures
provide a reasonable level of assurance that they are effective, they do not expect that the registrant’s disclosure controls
and procedures or internal control over financial reporting will prevent all errors and fraud. A control system, no matter how
well conceived or operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are
met.



|(c) | Management’s Annual Report on Internal Control Over Financial Reporting.
|--- | ------------------------------------------------------------------------



This Annual Report on Form 40-F does not include
a report of management’s assessment regarding internal control over financial reporting (as defined in Exchange Act Rules
13a-15(f) and 15d-15(f)) or the related attestation report of the registrant’s registered public accounting firm due to a
transition period established by rules of the SEC for newly public companies.



|(d) | Attestation Report of the Registered Public Accounting Firm. See item (c) immediately above.
|--- | --------------------------------------------------------------------------------------------



|(e) | Changes in Internal Control over Financial Reporting. During the fiscal year ended December 31, 2011, there were no changes in the registrant’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the registrant’s internal control over financial reporting.

Audit Committee Financial Experts



The registrant’s board of trustees has determined that
Colum Bastable, Paul D. McFarlane and Michael F. B. Nesbitt, all members of the registrant’s audit committee, qualify as
“independent” (as such term is defined in New York Stock Exchange Listed Company Manual (“NYSE Rules”))
and that Mr. McFarlane is an “audit committee financial expert” (as such term is defined in Form 40-F).



Code of Ethics



The registrant has adopted a “code of ethics” (as
that term is defined in Form 40-F), entitled the Code of Business Conduct and Ethics (the “Code of Ethics”), that applies
to all trustees, officers and employees.



The Code of Ethics, which complies with the NYSE Rules, is available
for viewing on the registrant’s website at www.brookfieldcanadareit.com, and is available in print to any shareholder who
requests it.  Requests for copies of the Code of Ethics should be made by contacting: Matthew Cherry, Director, Investor
Relations & Communications at Brookfield Canada Office Properties, Brookfield Place, 181 Bay Street, Suite 330, Toronto, Ontario,
Canada, M5J 2T3 or by email to matthew.cherry@brookfield.com.



All amendments to the Code of Ethics, and all waivers of the
Code of Ethics with respect to any trustee, officer or employee of the registrant, will be posted promptly on the registrant’s
website.



Principal Accountant Fees and Services



Deloitte & Touche LLP (“Deloitte & Touche”)
is the external auditor of the registrant.  From time to time, Deloitte & Touche has provided consulting and other
non-audit services to the registrant and its subsidiaries.



The information set forth under the heading “External
Auditor Service Fees (By Category)” under the “Audit Committee Information” section of the registrant’s
Annual Information Form for the fiscal year ended December 31, 2011, attached hereto as Exhibit 99.1, is incorporated by reference
herein. None of the fees billed by Deloitte & Touche in 2011 were for non-audit related services.



The Audit Committee of the board of trustees has determined
that the provision of these services is compatible with the maintenance of the independence of Deloitte & Touche.



Pre-Approval Policies and Procedures



The registrant has adopted the following policies and procedures
with respect to the pre-approval of audit and permitted non-audit services to be provided by Deloitte & Touche:



| | 1. | Deloitte & Touche may not be engaged to perform for the registrant, and is prohibited from performing for the registrant, any service enumerated in Section 201(a) of the Sarbanes-Oxley Act of 2002, except as may otherwise be provided by law or regulation.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | Deloitte & Touche may perform no services for the registrant, whether associated with audit or non-audit functions, unless the services to be provided have been approved prior to their performance by the registrant’s Audit Committee, except as may otherwise be provided by law or regulation.
| | -- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 3. | The registrant’s Audit Committee has approved a list of services that is sufficiently detailed as to the particular services to be provided to ensure that (i) the Audit Committee knows precisely what services it is being asked to pre-approve; and (ii) it is not necessary for any member of management to make a judgment as to whether a proposed service fits within the pre-approved services.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 4. | The authority to grant any pre-approval sought from the registrant’s Audit Committee has been delegated to the Audit Committee Chairperson, acting alone in respect of services for which estimated fees do not exceed $250,000; provided, however, that no such pre-approval may be granted with respect to any service proposed to be performed for the registrant by Deloitte & Touche that either is prohibited pursuant to Section 201(a) of the Sarbanes-Oxley Act of 2002 or otherwise appears reasonably likely to compromise Deloitte & Touche’s independence; and provided further, that any pre-approval granted pursuant to this delegation of authority will be reviewed with the Audit Committee at its next regularly scheduled meeting.
| | -- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



Off-Balance Sheet Arrangements



None.



Disclosure of Contractual Obligations



The information provided in the Management’s Discussion
and Analysis of Financial Results for the fiscal year ended December 31, 2011, included in Exhibit 99.2 as filed with this annual
report on Form 40-F, contains the registrant’s disclosure of contractual obligations and is incorporated by reference herein.



Identification of the Audit Committee



The registrant has a separately-designated standing Audit Committee
established in accordance with section 3(a)(58)(A) of the Exchange Act. The members of the Audit Committee are: Paul D. McFarlane
(Chairman), Colum Bastable and Michael F. B. Nesbitt.

Disclosure Pursuant to the Requirements of the New York Stock
Exchange.



Independence Requirements



The board of trustees is currently composed of seven trustees.
The board of trustees considers that its size and composition is appropriate given the diversity of the registrant’s operations
and the need for a variety of experience and backgrounds.  The board of trustees believes that a combination of independent
trustees, trustees related to the registrant’s parent company, Brookfield Office Properties Inc. (“BPO”) and
one trustee drawn from management leads to a constructive exchange in board deliberations resulting in objective, well-balanced
and informed discussion and decision making.



Each trustee must have an understanding of the registrant’s
principal operational and financial objectives, plans and strategies, financial position and performance as well as the performance
of the registrant relative to its principal competitors.  Trustees must have sufficient time to carry out their duties
and not assume responsibilities that would materially interfere with or be incompatible with board of trustees membership.  Trustees
who experience a significant change in their personal circumstances, including a change in their principal occupation, are expected
to advise, and submit a written resignation letter to, the Chairperson of the Governance and Nominating Committee and, if determined
appropriate by the board on the recommendation of the Governance and Nominating Committee resign from the board of trustees.



The board of trustees, with the assistance of the Governance
and Nominating Committee, determines whether each trustee is an independent trustee. In determining independence, the board of
trustees utilizes the definition of “independent” in the NYSE Rules and in National Instrument 52-110, “Audit
Committees” (“NI 52-110”).  In making these determinations, the board of trustees examines the results
of annual questionnaires completed by each trustee, as well as each individual trustee’s circumstances and his or her relationship
to the registrant and its affiliates.  For a trustee to be independent, the board must affirmatively determine that such
trustee has no material relationship with the registrant and, in the case of audit committee members, such trustee did not receive
any consulting, advisory, or other compensatory fee from the registrant except in his or her capacity as a member of the board
of trustees or a committee thereof.



The board has a policy that at least a majority of its trustees
should be independent trustees in order to ensure that the board’s interests are closely aligned with the interests of the
registrant’s shareholders.



The board of trustees has determined that a majority of its
trustees are independent, and has classified the 7 trustees as follows:



|* | Four independent trustees: Colum Bastable, Roderick D. Fraser,  Paul D. McFarlane and Michael F. B. Nesbitt. In determining that all of these trustees are independent, the board of trustees considered all relevant facts and circumstances, including that in the normal course of business, the registrant provides real estate and/or services to, and receives rental income and/or services from, companies with whom some of these trustees are affiliated.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|* | Two BPO trustees: Richard B. Clark and Thomas F. Farley.  While the board of trustees considers that Messrs. Clark’s and Farley’s interests are fully aligned with the interests of minority shareholders, and that they act independently of management, the applicable rules suggest that they be considered not independent.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|* | One management representative: T. Jan Sucharda, President and Chief Executive Officer, is not independent because he is a member of senior management of the registrant.
|- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------



There are no interlocking directorships among the board’s
independent trustees. Richard B. Clark serves as a board member of BPO, the registrant’s parent company.





Presiding Trustee at Meetings of Independent Trustees



The registrant schedules regular executive sessions at which
the registrant’s “independent directors” (as that term is defined in the NYSE Rules) meet without management
participation. Paul D. McFarlane serves as the chairmanat such sessions (the “Independent Designee”).



Communication with Non-Management Trustees



Shareholders may send communications to the registrant’s
non-management trustees by writing to Paul D. McFarlane, c/o Deborah R. Rogers, Brookfield Canada Office Properties, Brookfield
Place, 181 Bay Street, Suite 330, Toronto, Ontario, Canada, M5J 2T3 or by email to deborah.rogers@brookfield.com.  Communications
will be referred to theIndependent Designee for appropriate action.  The status of all outstanding concerns addressed
to theIndependent Designee will be reported to the board of trustees as appropriate.





Corporate Governance Guidelines



5









According to the NYSE Rules, a listed company must adopt and
disclose a set of corporate governance guidelines with respect to specified topics.  Such guidelines are required to
be posted on the registrant’s website.  The registrant’s corporate governance practices comply in all significant
respects with the NYSE Rules.  The Corporate Governance Guidelines are available for viewing on the registrant’s
website at www.brookfieldcanadareit.com and are available in print to any shareholder who requests them.  Requests
for copies of the Corporate Governance Guidelines should be made by contacting: Matthew Cherry, Director, Investor Relations &

2T3 or by email to matthew.cherry@brookfield.com.
