---

Management Report

The annual report, including the consolidated financial statements and Managements Discussion and Analysis (MD&A), is the responsibility of the
management of the Company. The consolidated financial statements were prepared by management in accordance with International Financial Reporting Standards. Where alternative accounting methods exist, management has chosen those it considers most
appropriate in the circumstances. The significant accounting policies used are described in note 4 to the consolidated financial statements. Certain amounts in the financial statements are based on estimates and judgments relating to matters not
concluded by year-end. The integrity of the information presented in the financial statements is the responsibility of management. Financial information presented elsewhere in this annual report has been prepared by management and is consistent with
the information in the consolidated financial statements.

The board of directors is responsible for ensuring that management fulfills its responsibilities
and for providing final approval of the annual consolidated financial statements. The board has appointed an Audit and Risk Committee comprising four directors; none are officers or employees of the Company or its subsidiaries. The Audit and Risk
Committee meets at least four times each year to discharge its responsibilities under a written mandate from the board of directors. The Audit and Risk Committee meets with management and with the external auditors to satisfy itself that it is
properly discharging its responsibilities; reviews the consolidated financial statements, MD&A, and Independent Auditors Report; and examines other auditing and accounting matters. The Audit and Risk Committee has reviewed the audited
consolidated financial statements with management and discussed the quality of the accounting principles as applied and the significant judgments affecting the consolidated financial statements. The Audit and Risk Committee has discussed with the
external auditors the external auditors judgments of the quality of those principles as applied and the judgments noted above. The consolidated financial statements and MD&A have been reviewed by the Audit and Risk Committee and approved
by the board of directors of Stantec Inc.

The consolidated financial statements have been examined by the shareholders auditors, Ernst &
Young LLP, Chartered Professional Accountants. The Independent Auditors Report outlines the nature of their examination and their opinion on the consolidated financial statements of the Company. The external auditors have full and unrestricted
access to the Audit and Risk Committee, with or without management being present.

Managements Annual Report on Internal Control over Financial
Reporting

Management is responsible for establishing and maintaining an adequate system of internal control over financial reporting. The
Companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
International Financial Reporting Standards. Management conducted an evaluation of the effectiveness of the system of internal control over financial reporting based on the framework in Internal Control  Integrated Framework issued by
the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, management concluded that the Companys system of internal control over financial reporting was effective as at December 31,
2015.

Ernst & Young LLP, which has audited the consolidated financial statements of the Company for the year ended December 31, 2015, has
also issued a report on the effectiveness of the Companys internal control over financial reporting.

As permitted by published guidance of the U.S.
Securities and Exchange Commission (SEC), managements evaluation of and conclusions on the effectiveness of internal control over financial reporting did not include the internal controls of Dessau Inc.; VI Engineering, LLC; VA Consulting,
Inc.; Fay, Spofford & Thorndike, Inc.; and the Infrastructure Americas Division of Kellogg Brown & Root Services, Inc., acquisitions which are included in the Companys 2015 consolidated financial statements. The aggregate
assets acquired were $129.2 million, representing 5.5% of the Companys total assets as at December 31, 2015. The gross revenue earned from their dates of acquisition to December 31, 2015, constituted 5.2% of the Companys gross
revenue for the year ended December 31, 2015.

Independent Auditors Report of Registered Public Accounting Firm

To the Board of Directors and Shareholders of Stantec Inc.:

We have audited the accompanying consolidated financial statements of Stantec Inc., which comprise the consolidated statements of financial position as at
December 31, 2015 and 2014, and the consolidated statements of income, comprehensive income, shareholders equity and cash flows for the years ended December 31, 2015 and 2014, and a summary of significant accounting policies and
other explanatory information.

Managements Responsibility for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of these consolidated financial statements in accordance with International Financial
Reporting Standards as issued by the International Accounting Standards Board, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material
misstatement, whether due to fraud or error.

Auditors Responsibility

Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with Canadian
generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance
about whether the consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence
about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors judgment, including the assessment of the risks of material misstatement of the consolidated financial statements,
whether due to fraud or error. In making those risk assessments, the auditors consider internal control relevant to the entitys preparation and fair presentation of the consolidated financial statements in order to design audit procedures that
are appropriate in the circumstances. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements, evaluating the appropriateness of accounting policies used and the
reasonableness of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.

We
believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Stantec Inc. as at December 31,
2015 and 2014, and its financial performance and its cash flows for the years ended December 31, 2015 and 2014 in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board.

Other Matter

We have also audited, in accordance with the
standards of the Public Company Accounting Oversight Board (United States), Stantec Inc.s internal control over financial reporting as at December 31, 2015, based on the criteria established inInternal Control  Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 24, 2016, expressed an unqualified opinion on Stantec Inc.s internal control over financial
reporting.

Independent Auditors Report on Internal Control over Financial Reporting

(Under the standards of the Public Company Accounting Oversight Board (United States))

To the Board of Directors and Shareholders of Stantec Inc.:

We have audited Stantec Inc.s internal control over financial reporting as at December 31, 2015, based on criteria established in Internal
ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Stantec Inc.s management is responsible for maintaining effective internal control over
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Managements Annual Report on Internal Control over Financial Reporting. Our responsibility is to express
an opinion on the Companys internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of
the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material
respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board (IFRS). A companys internal control over
financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the companys assets that could have a material effect on the
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As indicated in the accompanying Managements Annual Report on Internal Control over Financial Reporting, managements assessment of and conclusion
on the effectiveness of internal control over financial reporting did not include the internal controls of Dessau Inc.; VI Engineering, LLC; VA Consulting, Inc.; Fay, Spofford & Thorndike, Inc.; and the Infrastructure Americas Division of
Kellogg Brown & Root Services, Inc. which are included in the 2015 consolidated financial statements of Stantec Inc. The total assets acquired from these specified acquisitions represented 5.5% of Stantec Inc.s consolidated total
assets at December 31, 2015 and 5.2% of Stantec Inc.s consolidated gross revenue for the year then ended not subject to managements assessment of and conclusion on the effectiveness of internal control over financial reporting. Our
audit of internal control over financial reporting of Stantec Inc. also did not include an evaluation of the internal control over financial reporting of these specified acquisitions.

In our opinion, Stantec Inc. maintained, in all material respects, effective internal control over financial reporting as at December 31, 2015, based on
the COSO criteria.

We also have audited, in accordance with Canadian generally accepted auditing standards and the standards of the Public Company
Accounting Oversight Board (United States), the consolidated statements of financial position of Stantec Inc. as at December 31, 2015 and 2014, and the consolidated statements of income, comprehensive income, shareholders equity and cash
flows for the years ended December 31, 2015 and 2014, and our report dated February 24, 2016, expressed an unqualified opinion thereon.

control, and continue to be consolidated until the date that such control ceases. The statements of financial position of the subsidiaries and structured entities are prepared as at December 31, 2015. All intercompany balances are eliminated.

Joint ventures are accounted for using the equity method, and joint operations are accounted for by the Company recognizing its share of assets,
liabilities, revenue, and expenses of the joint operation.

4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

a) Cash and cash equivalents

Cash and cash equivalents include cash
and unrestricted investments. Such investments are carried at fair value.

b) Property and equipment

Property and equipment are recorded at cost less accumulated depreciation and any impairment losses. Cost includes the cost of replacing parts of property and
equipment. When significant parts of property and equipment are required to be replaced in intervals, the Company recognizes such parts as individual assets with specific useful lives and depreciation, respectively. All other repair and maintenance
costs are recognized in the consolidated statements of income as incurred.

Depreciation is calculated at annual rates designed to write off the costs of assets over their estimated useful
lives as follows:



|                       |  |            |  |                                                 
|---------------------- |  | ---------- |  | ------------------------------------------------
|Engineering equipment  |  | 20% to 30% |  | Declining balance                               
|Office equipment       |  | 20% to 30% |  | Declining balance                               
|Leasehold improvements |  |            |  | Straight-line over term of lease to a maximum of
|                       |  |            |  | 15 years or the improvements economic life     
|Other                  |  | 10% to 30% |  | Declining balance                               

The assets residual values, useful lives, and methods of depreciation are reviewed at each financial year-end and
adjusted prospectively, if appropriate.

c) Intangible assets

Intangible assets acquired separately are measured on initial recognition at cost. The cost of an intangible asset acquired in a business combination is its
fair value as at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and any impairment losses.

The Companys intangible assets have finite lives that are amortized over their useful economic lives on a straight-line basis. The amortization period
and the amortization method for an intangible asset with a finite useful life are reviewed at least at each financial year-end.

Intangible assets
acquired from business combinations

The Companys policy is to amortize client relationships with finite lives over periods ranging from 10 to 15
years. Contract backlog is amortized over estimated contractual lives of generally 1 to 2 years. Advantageous leasehold commitments are amortized over estimated lives of 1 to 10 years. The Company assigns value to acquired contract backlog and
client relationships using the income approach, which involves quantifying the present value of net cash flows attributed to the subject asset. This, in turn, involves estimating the revenues and earnings expected from the asset. Recognition of the
contributory assets, such as workforce, working capital, and property and equipment required and used to generate the expected after-tax earnings, is included since these assets also require a return based on their fair values. Expected earnings
after contributory charges and income taxes are discounted by the appropriate after-tax discount rate to arrive at the fair value.

Intangible
assetsSoftware

For internally generated software, research costs are expensed as incurred. Development expenditures on an individual project are
recognized as an intangible asset when the Company can demonstrate

| |  |  | The technical feasibility of completing the intangible asset so that it will be available for use
| | - |  | -------------------------------------------------------------------------------------------------

| |  |  | Its intention to complete and its ability to use the asset
| | - |  | ----------------------------------------------------------

| |  |  | How the asset will generate future economic benefits
| | - |  | ----------------------------------------------------

| |  |  | The availability of resources to complete the asset
| | - |  | ---------------------------------------------------

| |  |  | The ability to reliably measure the expenditure during development
| | - |  | ------------------------------------------------------------------

Following the initial recognition of the
development expenditure as an asset, it is carried at cost less any accumulated amortization and any impairment losses. Amortization of the asset begins when development is complete and the asset is available for use. The Company amortizes certain
purchased and internally generated software on a straight-line basis over periods ranging from three to seven years.

d) Leases

The determination of whether an arrangement is or contains a lease is based on the substance of the arrangement at the inception date. A lease is an agreement
whereby the lessor conveys to the lessee, in return for a payment or series of payments, the right to use an asset for an agreed period of time.

Finance
leases, which transfer to the Company substantially all the risks and benefits incidental to ownership of the leased items, are capitalized at the inception of the lease at the fair value of the leased asset or, if lower, at the present value of the
minimum lease payments. Lease payments are apportioned between finance charges and reduction of the



|                                               |  |      |  |

---

lease liability, achieving a constant rate of interest on the remaining balance of the liability. Finance charges are recognized in the consolidated statements of income.

Leased assets are depreciated over their useful lives. However, if there is no reasonable certainty that the Company will obtain ownership of the asset by the
end of the lease term, the asset is depreciated over the shorter of either its estimated useful life or the lease term. The Companys finance leases are for certain office and automotive equipment and are depreciated on a 20%-to-30% declining
balance basis. The Company also has finance leases for software, which are depreciated on a straight-line basis over periods ranging from three to seven years.

Rental payments under operating leases are expensed evenly over the lease term.

From time to time, the Company enters into or renegotiates premises operating leases that result in the receipt of lease inducement benefits. These benefits
are accounted for as a reduction of rental expense over the terms of the associated leases. As well, from time to time, the Company enters into or renegotiates premises operating leases that include escalation clauses. The scheduled rent increases
pursuant to lease escalation clauses are recognized on a straight-line basis over the lease terms.

e) Investments in joint arrangements and associates

Each joint arrangement of the Company is classified as either a joint venture or joint operation based on the rights and obligations arising from the
contractual obligations between the parties to the arrangement. A joint arrangement that provides the Company with rights to the net assets of the arrangement is classified as a joint venture, and a joint arrangement that provides the Company with
rights to the individual assets and obligations arising from the arrangement is classified as a joint operation.

The Company accounts for a joint venture
using the equity method, as described below. The Company accounts for a joint operation by recognizing its share of assets, liabilities, revenues, and expenses of the joint operation and combining them line by line with similar items in the
Companys consolidated financial statements.

Investments in associated companies, over which the Company is able to exercise significant influence
but not control, are accounted for using the equity method, which reflects the Companys investment at original cost plus postacquisition changes in the Companys share of the net assets of the associate. The share of the profit of
associates is recorded in the consolidated statements of income. Since this is profit attributable to the equity holders of the associate, it is profit after tax. Adjustments are made in the Companys consolidated financial statements to
eliminate its share of unrealized gains and losses resulting from transactions with its associates.

If the financial statements of the associates or
joint arrangements are prepared for a date that is different from the Companys date, adjustments are made for the effects of significant transactions or events that occur between that date and the date of the Companys financial
statements. Where necessary, adjustments are made to bring the accounting policies in line with the Companys.

f) Investments held for self-insured
liabilities

In other financial assets, the Company has investments held for self-insured liabilities that are categorized as available for sale and
are recorded at fair value, with associated unrealized gains or losses reported in other comprehensive income until disposed of, at which time realized gains or losses are recognized in income. These investments consist of government and corporate
bonds, equity securities, and term deposits.

g) Provisions

General

Provisions are recognized when the Company has a
present legal or constructive obligation as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the
obligation. When the Company expects some or all of a provision to be reimbursedfor example, under an insurance contractand when the reimbursement is virtually certain, the reimbursement is recognized as a separate asset. The expense
relating to any provision is presented in the consolidated statements of income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pretax rate that reflects, where appropriate,
the risks specific



|                                               |  |      |  |

|Notes to the Consolidated Financial Statements |  |      |  |

---

to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as a finance cost.

Provision for self-insured liabilities

The Company
self-insures certain risks related to professional liability, automobile physical damages, and employment practices liability. The provision for self-insured liabilities includes estimates of the costs of reported claims (including potential claims
that are probable of being asserted) and is based on estimates of loss using assumptions made by management, including consideration of actuarial projections. The provision for self-insured liabilities does not include unasserted claims where
assertion by a third party is not probable.

The Company invests funds to support the provision for self-insured liabilities. These investments are
recorded at fair value in other financial assets as investments held for self-insured liabilities.

Provisions for claims

The Company has claims that are not covered by its provisions for self-insurance, including claims that are subject to exclusions under the Companys
commercial and captive insurance policies. Provisions are recognized for these claims in accordance with the preceding general description of provisions.

Contingent liabilities recognized in a business combination

A contingent liability recognized in a business combination is initially measured at its fair value. Subsequently, it is measured in accordance with the
preceding general description of provisions.

Onerous contracts

The Companys onerous contracts consist of lease exit liabilities and sublease losses. For lease exit liabilities, the Company accrues charges when it
ceases to use an office space under an operating lease arrangement or it signs a new lease where an existing space will become vacant. Included in the liability is the present value of the remaining lease payments offset by the present value of
estimated future rental income.

From time to time, the Company may sublet a portion of office space that is under an operating lease arrangement. The
Company accrues a liability, a sublease loss, if the costs to be incurred under an operating lease will exceed the anticipated revenue on the sublease. Included in the liability is the present value of the remaining lease payments offset by the
present value of the future rental income.

h) Foreign currency translation

The Companys consolidated financial statements are presented in Canadian dollars, which is also the parent Companys functional currency. Each
entity in the Company determines its own functional currency, and items included in the financial statements of each entity are measured using that functional currency. For example, the functional currency of the Companys US-based subsidiaries
is the US dollar.

Transactions and balances

Transactions in foreign currencies (i.e., different than an entitys functional currency) are initially translated into the functional currency of an
entity using the foreign exchange rate at the transaction date. Subsequent to the transaction date, foreign currency transactions are measured as follows:



| |  |  | On the statements of financial position, monetary items are translated at the rate of exchange in effect at the reporting date. Non-monetary items at cost are translated at historical exchange rates. Non-monetary items
at fair value are translated at rates in effect at the date the fair value is determined. Any resulting realized and unrealized foreign exchange gains or losses are included in income in the period incurred. The exception is unrealized foreign
exchange gains and losses on non-monetary investments (equity investments) classified as available for sale, which are included in other comprehensive income.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Revenue and expense items are translated at the exchange rate on the transaction date, except for depreciation and amortization, which are translated at historical exchange rates.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|                                               |  |      |  |

---

Foreign operations

The Companys foreign operations are translated into its reporting currency (Canadian dollar) as follows:



| |  |  | Assets and liabilities are translated at the rate of exchange in effect at each consolidated statement of financial position date
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------



| |  |  | Revenue and expense items (including depreciation and amortization) are translated at the average rate of exchange for the month
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

The resulting unrealized exchange gains and losses on foreign subsidiaries are recognized in other comprehensive income.

i) Financial instruments

Initial recognition and
subsequent measurement

The Company classifies its financial instruments as follows:



| |  |  | Cash and cash equivalents and cash in escrow are classified as financial assets at fair value through profit and loss (FVPL) and are recorded at fair value, with realized and unrealized gains and losses reported in
income.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trade and other receivables are classified as receivables and are initially accounted for at fair value and subsequently adjusted for any allowance for doubtful accounts, with allowances reported in administrative and
marketing expenses.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Investments held for self-insured liabilities, consisting of bonds, equity securities, and term deposits, are classified as financial assets available for sale and are recorded at fair value, with accumulated unrealized
gains and losses reported in other comprehensive income until disposed of; at this time, the realized gains and losses are recognized in other income for equity securities and in finance income for bonds and term deposits. Interest income is
recorded in finance income, and dividends are recorded in other income.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Trade and other payables are classified as other financial liabilities and are recorded at fair value and subsequently recorded at amortized cost using the effective interest rate (EIR) method. Realized gains and losses
are reported in income. The EIR method discounts estimated future cash payments or receipts through the expected life of a financial instrument, thereby calculating the amortized cost and subsequently allocating the interest income or expense over
the life of the instrument.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Long-term debts are classified as loans and borrowings and are initially recorded at fair value and subsequently recorded at amortized cost using the EIR method. EIR amortization and realized gains and losses are
reported in net finance expense.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Fair value

All financial assets are recognized initially at fair value plus directly attributable transaction costs, except for financial assets at FVPL, for which
transaction costs are expensed. Purchases or sales of financial assets are accounted for at trade dates. All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings, net of directly attributable
transaction costs.

After initial recognition, the fair values of financial instruments are based on the bid prices in quoted active markets for financial
assets and on the ask prices for financial liabilities. For financial instruments not traded in active markets, fair values are determined using appropriate valuation techniques, which may include recent arms-length market transactions,
reference to the current fair value of another instrument that is substantially the same, and discounted cash flow analysis; however, other valuation models may be used. The fair values of the Companys derivatives are based on third-party
indicators and forecasts. The fair values of cash and cash equivalents, cash in escrow, trade and other receivables, and trade and other payables approximate their carrying amounts because of the short-term maturity of these instruments. The
carrying amounts of bank loans approximate their fair values because the applicable interest rate is based on variable reference rates. The carrying amounts of other financial assets and financial liabilities approximate their fair values except as
otherwise disclosed in the consolidated financial statements.

---

Derivatives

From time to time, the Company enters into foreign currency forward contracts to manage risk associated with net operating assets or liabilities denominated in
US dollars and British pounds. The Companys policy is not to use these derivatives for trading or speculative purposes. In addition, the Company enters into software licensing agreements that have foreign currencyembedded derivatives.
During 2015 and 2014, these derivatives did not have a material impact on the Companys financial position or performance.

j) Impairment

The carrying amounts of the Companys assets or group of assets, other than deferred tax assets, are reviewed at each reporting date to determine whether
there is an indication of impairment. An asset may be impaired if there is objective evidence of impairment as a result of one or more events that have occurred after the initial recognition of the asset (referred to as a loss event) and
if that loss event has an impact on the estimated future cash flows of the financial asset. When an indication of impairment exists or annual impairment testing for an asset is required, the assets recoverable amount is estimated.

Trade and other receivables

The Company maintains an
allowance for doubtful accounts on trade receivables. The estimate is based on the best assessment of the collectibility of the related receivable balance based in part on the age of the outstanding receivables and the Companys historical
collection and loss experience. When the carrying amount of the receivable is reduced through the allowance, the reduction is recognized in administrative and marketing expenses in the consolidated statements of income.

Non-financial assets

For non-financial assets such as
property and equipment, goodwill, investments in joint ventures and associates, and intangible assets, the recoverable amount is the higher of an assets or cash-generating units (CGUs) value in use or its fair value less costs of
disposal. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. Where the carrying amount of an asset or CGU exceeds
its recoverable amount, the asset is considered impaired and is written down to its recoverable amount. To assess value in use, the estimated future cash flows are discounted to their present value using a pretax discount rate that reflects current
market assessments of the time value of money and the risks specific to the asset. To determine fair value less costs of disposal, an appropriate valuation model is used. The results of these valuation techniques are corroborated by the market
capitalization of comparable public companies and arms-length transactions of comparable companies. Impairment losses are recognized in the consolidated statements of income in those expense categories that are consistent with the nature of
the impaired asset.

Goodwill is not amortized but is evaluated for impairment annually (as at October 1) or more frequently if circumstances
indicate that an impairment may occur or if a significant acquisition occurs between the annual impairment test date and December 31. The Company considers the relationship between its market capitalization and its book value, as well as other
factors, when reviewing for indicators of impairment. Impairment is determined by assessing the recoverable amount of each CGU to which the goodwill relates. Where the recoverable amount of a CGU is less than its carrying amount, an impairment loss
is recognized. The Companys CGUs for goodwill impairment testing are Canada, the United States, and International.

An impairment loss of goodwill
is not reversed. For other assets, an impairment loss may be reversed if the estimates used to determine the recoverable amount have changed. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount or
the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. The reversal is recognized in the consolidated statements of income.

Available-for-sale financial investments

For equity
investments classified as available for sale, objective evidence of impairment would include a significant or prolonged decline in the fair value of the investment below its cost. Significant is evaluated against the original cost of the
investment and prolonged against the period in which the fair value has been below its original cost.



|                                               |  |      |  |

---

Where there is evidence of impairment, the cumulative loss is removed from other comprehensive income and
recognized in the consolidated statements of income. Impairment losses on equity investments are not reversed through the consolidated statements of income; increases in their fair value after impairment are recognized directly in other
comprehensive income.

For debt instruments (such as bonds) classified as available for sale, the Company first assesses individually whether objective
evidence of impairment exists for debt instruments that are individually significant or collectively for debt instruments that are not individually significant. If an impairment loss has occurred, the amount recorded is the cumulative loss, measured
as the difference between the amortized cost and the current fair value, less any previously recognized impairment loss. This amount is removed from other comprehensive income and recognized in the consolidated statements of income.

Future interest income continues to be accrued based on the reduced carrying amount of the asset applying the rate of interest used to discount the future
cash flows for the purpose of measuring the impairment loss. If the fair value of a debt instrument increases in a subsequent year and the increase can be objectively related to an event occurring after the impairment loss was recognized, the
impairment loss is reversed in the consolidated statements of income.

k) Revenue recognition

While providing services, the Company incurs certain direct costs for subconsultants and other expenditures that are recoverable directly from clients. These
direct costs are included in the Companys gross revenue. Since these direct costs can vary significantly from contract to contract, changes in gross revenue may not be indicative of the Companys revenue trends. Therefore, the Company
also reports net revenue, which is gross revenue less subconsultant and other direct expenses.

Revenue is recognized to the extent that it is probable
that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured at the fair value of the consideration received, excluding discounts, duty, and taxes collected from clients that are reimbursable to
government authorities. The Company assesses its revenue arrangements against specific criteria to determine if it is acting as a principal or an agent. The Company has concluded that it is acting as a principal in all of its revenue arrangements.

Revenue from fixed-fee and variable-fee-with-ceiling contracts is recognized by referring to the stage of completion using the revenue cost approach.
Stage of completion is measured using labor costs incurred to date as a percentage of total estimated labor costs for each contract. Where the contract outcome cannot be measured reliably, revenue is recognized only to the extent that the expenses
incurred are eligible to be recovered. Provisions for estimated losses on incomplete contracts are made in the period that the losses are determined. Revenue from time-and-material contracts without stated ceilings and from short-term projects is
recognized as costs are incurred. Revenue is calculated based on billing rates for the services performed.

Unbilled revenue represents work in progress
that has been recognized as revenue but has not yet been invoiced to clients. Billings in excess of costs represent amounts that have been invoiced to clients but not yet recognized as revenue.

l) Employee benefits plans

The Company contributes to group
retirement savings plans and an employee share purchase plan based on the amount of employee contributions and subject to maximum limits per employee. The Company accounts for defined contributions as an expense in the period in which the
contributions are made. The Company does not provide postemployment or postretirement benefits.

m) Taxes

Current income tax

Current income tax assets and
liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at
the reporting date in the countries where the Company operates and generates taxable income.



|                                               |  |      |  |

---

Current income tax that relates to items recognized directly in equity is recognized in equity and not in the
consolidated statements of income. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes an uncertain tax liability where
appropriate.

Deferred tax

Deferred tax is
determined using the liability method for temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes. Deferred tax liabilities are generally recognized for
all taxable temporary differences. Deferred tax assets are recognized for all deductible temporary differences, carryforward of unused tax credits and unused tax losses, to the extent that it is probable that taxable profit will be available against
which the deductible temporary differences and the carryforward of unused tax credits and unused tax losses can be utilized. Deferred taxes are not recognized for the initial recognition of goodwill; the initial recognition of assets or liabilities,
outside of a business combination, that affect neither accounting nor taxable profit; or the differences relating to investments in associates and interests in joint ventures to the extent that the reversal can be controlled and it is probable that
it will not reverse in the foreseeable future.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent
that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are reassessed at each reporting date and are recognized to the extent
that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are
measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled and are based on tax rates and tax laws that have been enacted or substantively enacted at the reporting date.

Deferred tax relating to items recognized in equity is also recognized in equity. Deferred tax items are recognized in correlation to the underlying
transaction either in other comprehensive income or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally
enforceable right exists to set off tax assets against tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Sales tax

Revenues, expenses, and assets, except trade
receivables, are recognized net of the amount of sales tax recoverable from or payable to a taxation authority. Trade receivables and trade payables include sales tax. The net amount of sales tax recoverable from or payable to a taxation authority
is included as part of trade receivables or trade payables (as appropriate) in the consolidated statements of financial position.

n) Share-based payment
transactions

Under the Companys share option plan, the board of directors may grant to officers and employees remuneration in the form of
share-based payment transactions, whereby officers and employees render services as consideration for equity instruments (equity-settled transactions).

Under the Companys deferred share unit plan, the directors of the board of the Company may receive deferred share units (DSUs) equal to one common
share. Before 2014, the chief executive officer could also receive DSUs. For the restricted share unit plan, senior vice presidents may be granted share units that are to be settled after a two-year period. Under the Companys long-term
incentive plan, certain members of the senior leadership teams, including the chief executive officer, are granted performance share units (PSUs) that vest and are to be settled after a three-year period. The DSUs, restricted share units (RSUs), and
PSUs are share appreciation rights that can be settled only in cash (cash-settled transactions).

Equity-settled transactions

The cost of equity-settled transactions awards is measured at fair value at the grant date using a Black-Scholes option-pricing model. The cost of
equity-settled transactions, together with a corresponding increase in equity, is recognized over the period in which the service conditions are fulfilled (the vesting period). For equity-settled transactions, the cumulative expense recognized at
each reporting date until the vesting date reflects the extent to

which the vesting period has expired and reflects the Companys best estimate of the number of equity
instruments that will ultimately vest. The expense or credit to income for a period represents the movement in cumulative expense recognized as at the beginning and end of that period and is recorded in administrative and marketing expenses. No
expense is recognized for awards that do not ultimately vest.

Cash-settled transactions

The cost of cash-settled transactions is measured initially at fair value at the grant date using a Black-Scholes option-pricing model. This fair value is
expensed upon issue with the recognition of a corresponding liability. The liability is remeasured to fair value at each reporting date, up to and including the settlement date, with changes in fair value recognized in administrative and marketing
expenses.

o) Earnings per share

Basic earnings per share is
computed based on the weighted average number of common shares outstanding during the year. Diluted earnings per share is computed using the treasury stock method, which assumes that the cash that would be received on the exercise of options is
applied to purchase shares at the average price during the year and that the difference between the number of shares issued on the exercise of options and the number of shares obtainable under this computation, on a weighted average basis, is added
to the number of shares outstanding. Antidilutive options are not considered in computing diluted earnings per share.

p) Business combinations and goodwill

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the consideration transferred at fair
value at the acquisition date. Any contingent consideration to be transferred by the Company is recognized at fair value at the acquisition date. Subsequent changes to the fair value of the contingent consideration are recognized in other income.
Acquisition costs are expensed when incurred in administrative and marketing expenses.

Goodwill is initially measured at cost, which is the excess of the
consideration transferred over the fair value of a Companys net identifiable assets acquired and liabilities assumed. If this consideration is lower than the fair value of the net assets acquired, the difference is recognized in income.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill acquired in a
business combination is, from the acquisition date, allocated to each CGU (Canada, United States, or International) that is expected to benefit from the combination, irrespective of whether other assets or liabilities of the acquiree are assigned to
those units.

q) Dividends

Dividends on common shares are
recognized in the Companys consolidated financial statements in the period the dividends are declared by the Companys board of directors.

5. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES, AND ASSUMPTIONS

Preparation of the Companys consolidated financial
statements requires management to make judgments, estimates, and assumptions that affect the reported amounts of revenues, expenses, assets, and liabilities, as well as the disclosure of contingent liabilities at the end of the reporting year.
However, uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of the asset or liability affected in future periods.

Discussed below are the key management judgments and assumptions concerning the future and other key sources of estimation uncertainty at the reporting date
that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year.

a) Revenue
recognition

The Company accounts for its revenue in accordance with IAS 11Construction Contracts, which requires estimates to be made for
contract costs and revenues. Revenue from fixed-fee and variable-fee-with-ceiling contracts is recognized using the percentage of completion method based on the ratio of labor costs incurred to total estimated labor costs. Estimating total direct
labor costs is subjective and requires the use of managements best judgments based on the information available at that time. The Company also provides for estimated losses on

---

incomplete contracts in the period in which such losses are determined. Changes in the estimates are reflected in the period in which they are made and affect the Companys revenue and
unbilled revenue.

b) Allowance for doubtful accounts

The
Company maintains an allowance for doubtful accounts for estimated losses resulting from the inability to collect on its trade receivables. The Company uses estimates in arriving at its allowance for doubtful accounts. The estimates are based on the
age of the outstanding receivables and on the Companys historical collection and loss experience. Future collections of receivables that differ from the Companys current estimates would affect the results of our operations in future
periods as well as the Companys trade receivables and administrative and marketing expenses.

c) Provision for self-insured liabilities

The Company self-insures certain risks, including professional liability, automobile liability, and employment practices liability. The accrual for
self-insured liabilities includes estimates of the costs of reported claims and is based on estimates of loss using managements assumptions, including consideration of actuarial projections. These estimates of loss are derived from loss
history that is then subjected to actuarial techniques to determine the proposed liability. Estimates of loss may vary from those used in the actuarial projections and result in a larger loss than estimated. Any increase in loss would be recognized
in the period in which the loss is determined and increase the Companys self-insured liabilities and reported expenses.

d) Share-based
payment transactions

The Company measures the cost of share-based payment transactions by reference to the fair value of the equity instruments at the
grant date. Estimating fair value for share-based payment transactions requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the grant. The Company has chosen the Black-Scholes option-pricing
model for equity-settled and cash-settled share-based payment transactions.

Estimating fair value also requires determining the most appropriate
inputs to the valuation modelincluding volatility in the price of the Companys shares, a risk-free interest rate, and the expected hold period to exerciseand making assumptions about them. The expected volatility is based on the
historical volatility of the Companys shares over a period commensurate with the expected term of the share option. The risk-free interest rate for the expected life of the options is based on the yield available on government bonds, with an
approximate equivalent remaining term at the time of the grant. Historical data is used to estimate the expected life of the option. As well, the Company estimates its forfeiture rate for equity-settled transactions based on historical experience to
determine the compensation expense arising from the share-based awards. Changes to estimates are recorded in the period in which they are made and would affect the Companys administrative and marketing expenses, contributed surplus, and other
liabilities.

e) Business combinations

In a
business combination, the Company may acquire certain assets and assume certain liabilities of an acquired entity. The estimate of fair values for these transactions involves judgment to determine the fair values assigned to the tangible and
intangible assets (i.e., backlog, client relationships, and favorable and unfavorable leases) acquired and the liabilities assumed on the acquisition. Determining fair values involves a variety of assumptions, including revenue growth rates,
expected operating income, and discount rates. During a measurement period, not to exceed one year, adjustments of the initial estimates may be required to finalize the fair value of assets acquired and liabilities assumed. After the measurement
period, a revision of fair value may impact the Companys net income.

f) Impairment of non-financial assets

Impairment exists when the carrying amount of an asset or CGU exceeds its recoverable amount, which is the higher of its fair value less costs of disposal or
its value in use. Fair value less costs of disposal is based on available data from binding sales transactions in an arms-length transaction of similar assets or observable market prices less incremental costs for disposing of the asset. In
the absence of this data, other valuation techniques can be used to estimate fair value less costs of disposal. The value in use calculation is based on a discounted cash flow model. The cash flows are derived from budgets over an appropriate number
of years and do not include restructuring activities that the Company is not yet committed to or significant future investments that will enhance the assets performance of the CGU being tested.

When based on a discounted cash flow methodology, the recoverable amount is most sensitive to the expected future cash inflows, the growth rate used for
extrapolation purposes, and the discount rate. To arrive at cash flow

---

projections, the Company uses estimates of economic and market information over the projection period, including growth rates in revenues, estimates of future expected changes in operating
margins, and cash expenditures. Other significant estimates and assumptions include future estimates of capital expenditures and changes in future working capital requirements.

g) Fair value of financial instruments

When the fair value
of financial assets and financial liabilities recorded in the consolidated statements of financial position cannot be derived from active markets, it is determined using valuation techniques, including the discounted cash flow model. The inputs to
these models are taken from observable markets if possible, but when this is not feasible, a degree of judgment is required to establish fair values. The judgments include considering inputs such as liquidity risk, credit risk, and volatility.
Changes in assumptions about these factors could affect the reported fair value of financial instruments and reported expenses and income.

h) Taxes

Uncertainties exist with respect to the interpretation of complex tax regulations and the amount and timing of deferred taxable income. The Companys
income tax assets and liabilities are based on interpretations of income tax legislation across various jurisdictions, primarily in Canada and the United States. The Companys effective tax rate can change from year to year based on the mix of
income among different jurisdictions, changes in tax laws in these jurisdictions, and changes in the estimated value of deferred tax assets and liabilities. The Companys income tax expense reflects an estimate of the taxes it expects to pay
for the current year, as well as a provision for changes arising in the values of deferred tax assets and liabilities during the year. The tax value of these assets and liabilities is impacted by factors such as accounting estimates inherent in
these balances, managements expectations about future operating results, previous tax audits, and differing interpretations of tax regulations by the taxable entity and the responsible tax authorities. Differences in interpretation may arise
for a wide variety of issues, depending on the conditions prevailing in the respective legal entitys domicile. On a regular basis, management assesses the likelihood of recovering value from deferred tax assets, such as loss carryforwards, as
well as from deferred tax depreciation of capital assets, and adjusts the tax provision accordingly.

Deferred tax assets are recognized for all unused
tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant management judgment is required to determine the amount of deferred tax assets that can be recognized based on
the likely timing and the level of future taxable profits, together with future tax-planning strategies. If estimates change, the Company may be required to recognize an adjustment to its deferred income tax asset or liability and income tax
expense.

i) Interests in other entities

The Company determines
whether it has control over another entity by making judgments about what the relevant activities of that entity are and which party or parties have power to direct those activities, as well as whether the Company is exposed to variable returns of
the entity. The Company assesses whether it has control, significant influence, or joint control over an entity based on the individual facts and circumstances of each agreement. In the case of a joint arrangement, the Company makes judgments to
determine if the arrangement is a joint venture or joint operation, including whether it has rights to the individual assets or liabilities or to the net assets of the entity and whether unanimous consent is required to make decisions about relevant
activities.

Future adoptions

The
listing below includes standards, amendments, and interpretations that the Company reasonably expects to be applicable at a future date and intends to adopt when they become effective. The Company is currently considering the impact of adopting
these standards, amendments, and interpretations on its consolidated financial statements and cannot reasonably estimate the effect at this time.



| |  | In May 2014, the IASB issued IFRS 15 Revenue from Contracts with Customers(IFRS 15). IFRS 15 applies to all revenue contracts with customers and provides a model for the recognition and measurement of the sale
of some non-financial assets such as property, plant, and equipment, and intangible assets. IFRS 15 sets out a five-step model for revenue recognition and applies to all industries. The core principle is that revenue should be recognized to depict
the transfer of promised goods or services to customers in an amount that reflects the consideration that the entity expects to be entitled to in exchange for those goods or services. IFRS 15 requires numerous disclosures, such as the disaggregation
of total revenue, disclosures about performance obligations, changes in contract asset and liability account balances, and key judgments and estimates. This standard may be adopted using a full retrospective or modified retrospective approach. In
September 2015, the IASB issued Effective Date of IFRS 15 (Amendment to IFRS 15 Revenue from Contracts)which changed the mandatory effective date of IFRS 15 from January 1, 2017, to January 1, 2018.

| |  | In May 2014, the IASB issued Accounting for Acquisitions of Interests in Joint Operations (Amendments to IFRS 11). The amendments provide guidance on accounting for acquisitions of interests in joint operations
in which the activity constitutes a business, as defined by IFRS 3. The acquirer applies all principles on business combinations accounting in IFRS 3 and other IFRSs, except for those principles that conflict with the guidance in IFRS 11 Joint
Arrangements. In addition, the acquirer must disclose the information required by IFRS 3 and other IFRSs for business combinations. This amendment is effective January 1, 2016, on a prospective basis.

| |  | In July 2014, the IASB issued IFRS 9 Financial Instruments (IFRS 9) to replace IAS 39 Financial Instruments: Recognition and Measurement. IFRS 9 provides a revised model for the recognition and measurement
of financial assets, financial liabilities, and some contracts to buy or sell non-financial items. In addition, it includes a single expected-loss impairment model and a reformed approach to hedge accounting. This standard is effective
January 1, 2018, on a retrospective basis subject to certain exceptions.

| |  | In September 2014, the IASB issued Sale or Contribution of Assets between an Investor and Its Associate or Joint Venture (Amendments to IFRS 10 Consolidated Financial Statements and IAS 28 Investments in Associates
and Joint Ventures). The amendments clarify how to recognize gains or losses when a sale of a business or assets from a subsidiary to a joint venture or associate results in the loss of control of the subsidiary. These amendments are effective
January 1, 2016, on a prospective basis. In December 2015, the IASB issuedEffective Date of Amendments to IFRS 10 and IAS 28which changed the mandatory effective date to a date to be determined by the IASB.

January 1, 2016.
|- |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  | In January 2016, the IASB issued IFRS 16 Leases(IFRS 16) which requires lessees to recognize assets and liabilities for most leases. Lessees will have a single accounting model for all leases, with certain
exemptions. For lessors, there is little change to the existing accounting in IAS 17 Leases.The new standard is effective January 1, 2019, with limited early application permitted. The new standard permits lessees to use either a full
retrospective or a modified retrospective approach on transition for leases existing at the date of transition, with options to use certain transition reliefs.

7. BUSINESS ACQUISITIONS

Acquisitions are accounted for under the acquisition method of accounting and the results of operations since the respective dates of acquisition are included
in the consolidated statements of income. From time to time, as a result of the timing of acquisitions in relation to the Companys reporting schedule, certain estimates of fair values of assets and liabilities acquired may not be finalized at
the initial time of reporting. These estimates are completed after the vendors final financial statements and income tax returns have been prepared and accepted by the Company and when the valuation of intangible assets acquired is finalized.
The preliminary fair values are based on managements best estimates of the acquired identifiable assets and liabilities at the acquisition date. During a measurement period not to exceed one year, adjustments to the initial estimates may be
required to finalize the fair value of assets and liabilities acquired. The Company will revise comparative information if these measurement period adjustments are material.

The consideration paid for acquisitions may be subject to price adjustment clauses included in the purchase agreements and may extend over a number of years.
At each consolidated statement of financial position date, these price adjustment clauses are reviewed. This may result in an increase in or a reduction of the notes payable consideration (recorded on the acquisition date) to reflect either more or
less non-cash working capital than was originally recorded. Since these adjustments are a result of facts and circumstances occurring after the acquisition date, they are not considered measurement period adjustments.

For some acquisitions, additional payments may be made to the employees of an acquired company that are based on the employees continued service over an
agreed time period. These additional payments are not included in the purchase price. They are expensed as compensation when services are provided by the employees.

Trade receivables assumed from acquired companies are recognized at fair value at the time of acquisition. In 2015, trade
receivables acquired had a fair value of $82,913,000 and gross value of $86,701,000.

Goodwill consists of the value of expected synergies arising from an
acquisition, the expertise and reputation of the assembled workforce acquired, and the geographic location of the acquiree. Of the goodwill and intangible assets resulting from acquisitions completed in 2015, $76,967,000 is deductible for income tax
purposes.

The fair value of provisions is determined at the acquisition date. These liabilities relate to claims that are
subject to legal arbitration and onerous contracts. During 2015, the Company assumed $8,746,000 in provisions for claims relating to current year acquisitions (2014  $672,000). At the reporting date, provisions for claims outstanding were
reassessed and determined to be

$11,295,000, based on their expected probable outcome. Certain of these claims are indemnified by the acquiree (note 14).

For business combinations that occurred in 2015, the Company estimates that gross revenue earned in 2015, since the acquired entities acquisition
dates, is $177,408,000. The Company integrates the operations and systems of acquired entities shortly after the acquisition date; therefore, it is impracticable to disclose the acquirees earnings in its consolidated financial statements since
the acquisition date.

If the business combinations that occurred in 2015 had taken place at the beginning of 2015, gross revenue from continuing
operations for 2015 would have been $3,020,530,000 and the profit from continuing operations would have been $157,890,000.

In 2015, directly attributable
acquisition-related costs of $755,000 have been expensed and are included in administrative and marketing expenses.

The Company maintains an allowance for estimated losses on trade receivables. The estimate is based on the best assessment of
the collectibility of the related receivable balance, which is determined in part based on the age of the outstanding receivables and the Companys historical collection and loss experience.

The following table provides a reconciliation of changes to the Companys allowance for doubtful accounts.

Goodwill arising from acquisitions includes factors such as the expertise and reputation of the assembled workforce acquired,
the geographic location of the acquiree, and the expected synergies.

The Company allocates goodwill to its CGUs, which are also its operating segments.
The Companys CGUs are Canada, the United States, and International. These CGUs are defined based on the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or
groups of assets. Other factors are considered, including how management monitors the entitys operations. The Company does not monitor goodwill at, or allocate goodwill to, its business operating units.

On October 1, 2015, and October 1, 2014, the Company performed its annual goodwill impairment test in accordance with its policy described in note
4. Based on the results of the 2015 and 2014 tests, the Company concluded that the recoverable amount of each CGU exceeded its carrying amount and, therefore, goodwill was not impaired.

The Company has allocated its goodwill to its CGUs as follows:

Management believes that the methodology used to test impairment of goodwill, which involves a significant number of judgments
and estimates, provides a reasonable basis for determining whether an impairment has occurred. Many factors used to determine whether goodwill is impaired are outside of managements control and involve inherent uncertainty. Therefore, actual
results could differ from those estimated.

Valuation techniques

When performing the goodwill impairment test, the Company compares the recoverable amount for each CGU to its carrying amount. If the carrying amount of a CGU
is higher than its recoverable amount, an impairment charge is recorded as a reduction in the carrying amount of the goodwill on the consolidated statements of financial position and recognized as a non-cash impairment charge in income.

The Company estimates the recoverable amount by using the fair value less costs of disposal approach. It
estimates fair value using market information and discounted after-tax cash flow projections, which is known as the income approach. The income approach uses a CGUs projection of estimated operating results and discounted cash flows based on a
discount rate that reflects current market conditions and the risk of achieving the cash flows. The Company uses cash flow projections covering a five-year period from financial forecasts approved by senior management. For its October 1, 2015,
and October 1, 2014, impairment tests, the Company discounted the cash flows for each CGU using an after-tax discount rate ranging from 8.7% to 11.5%. To arrive at cash flow projections, the Company used estimates of economic and market
information over the projection period (note 5).

The Company validates its estimate of the fair value of each CGU under the income approach by comparing
the resulting multiples to multiples derived from comparable public companies and comparable company transactions. The Company reconciles the total fair value of all CGUs with its market capitalization to determine if the sum is reasonable. If the
reconciliation indicates a significant difference between the external market capitalization and the fair value of the CGUs, the Company reviews and adjusts, if appropriate, the discount rate of a CGU and considers whether the implied acquisition
premium is reasonable in light of current market conditions. The fair value measurement was categorized as a level 3 fair value based on the significant inputs in the valuation technique used (note 22).

If market and economic conditions deteriorate or if volatility in the financial markets causes declines in the Companys share price, increases the
weighted average cost of capital, or changes valuation multiples or other inputs to its goodwill assessment, the Company may need to test its goodwill for impairment between its annual test dates. In addition, changes in the numerous variables
associated with the judgments, assumptions, and estimates made by management in assessing the fair value of the Companys CGUs could cause them to be impaired. Goodwill impairment charges are non-cash charges that could have a material adverse
effect on the Companys consolidated financial statements but in themselves do not have any adverse effect on its liquidity, cash flows from operating activities, or debt covenants and will not have an impact on its future operations.

Key assumptions

The calculation of fair value less costs of
disposal for all CGUs is most sensitive to the following assumptions:



| |  |  | Operating margins based on actual experience and managements long-term projections.
| | - |  | ------------------------------------------------------------------------------------



| |  |  | Discount rates reflecting investors expectations when discounting future cash flows to a present value, taking into consideration market rates of return, capital structure, company size, and industry risk. If
necessary, a discount rate is further adjusted to reflect risks specific to a CGU when future estimates of cash flows have not been adjusted.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Growth rate estimates based on actual experience and market analysis. Projections are extrapolated beyond five years using a growth rate that typically does not exceed 3.0%.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Sensitivity to changes in assumptions

As at October 1, 2015,
the recoverable amount of the Companys Canadian and US CGUs exceeded their carrying amount. For the assessment of fair value less costs of disposal, management believes that no reasonably possible change in any of the above key assumptions
would have caused the carrying amount of the Canadian or US CGU to exceed its recoverable amount.

Once an intangible asset is fully amortized, the gross carrying amount and related accumulated amortization are removed from
the accounts. Other than goodwill, the Company has not recorded any intangible assets with indefinite lives. Included in software are finance leases with a net book value of $22,560,000 (2014  $11,001,000) and $1,099,000 (2014  $414,000)
in internally generated software that is not ready for use and, therefore, is not being amortized.

In accordance with its accounting policies in note 4,
the Company tests intangible assets for recoverability when events or changes in circumstances indicate that their carrying amount may not be recoverable. To determine indicators of impairment of intangible assets, the Company considers external
sources of information such as prevailing economic and market conditions and internal sources of information such as the historical and expected financial performance of the intangible assets. If indicators of impairment are present, the Company
determines

recoverability based on an estimate of discounted cash flows, using the higher of either the value in use or the fair value less costs of disposal methods. The measurement of impairment loss is
based on the amount that the carrying amount of an intangible asset exceeds its recoverable amount. As part of the impairment test, the Company updates its future cash flow assumptions and estimates, including factors such as current and future
contracts with clients, margins, market conditions, and the useful lives of the assets. During 2015, the Company concluded that there were no material indicators of impairment to intangible assets.

Notes payable

Notes payable
consists primarily of notes payable for acquisitions (note 7). The weighted average rate of interest on the notes payable is 3.63% (2014  3.65%). The notes may be supported by promissory notes and are due at various times from 2016 to 2019.
The aggregate maturity value of the notes is $126,840,000 (2014  $113,726,000). At December 31, 2015, $117,282,000 (US$84,741,000) (2014  $100,207,000 (US$86,378,000)) of the notes carrying amount was payable in US funds.

Bank loan

The Company has entered into an agreement for a $350
million revolving credit facility expiring August 2018. This facility allows the Company access to an additional $150 million under the same terms and conditions on approval from its lenders. The facility is available for future acquisitions,
working capital needs, and general corporate purposes. All Company assets are held as collateral under a general security agreement for the revolving credit facility and the senior secured notes. Depending on the form under which the credit facility
is accessed, rates of interest will vary between Canadian prime, US base rate, and LIBOR or bankers acceptance rates, plus specified basis points. The specified basis points may vary, depending on the Companys level of consolidated debt

In the normal conduct of operations, various legal claims are pending against the Company, alleging, among other
things, breaches of contract or negligence in connection with the performance of consulting services. The Company carries professional liability insurance, subject to certain deductibles and policy limits, and has a captive insurance company that
provides insurance protection against such claims. In some cases, parties are seeking damages that substantially exceed the Companys insurance coverage. Based on advice and information provided by legal counsel, the Companys previous
experience with the settlement of similar claims, and the results of the annual actuarial review, management believes that the Company has recognized adequate provisions for probable and reasonably estimated liabilities associated with these claims.
In addition, management believes that it has appropriate insurance in place to respond to and offset the cost of resolving these claims.

Due to
uncertainties in the nature of the Companys legal claims, such as the range of possible outcomes and the progress of the litigation, provisions accrued involve estimates. The ultimate cost to resolve these claims may exceed or be less than
that recorded in the consolidated financial statements. Management believes that the ultimate cost to resolve these claims will not materially exceed the insurance coverage or provisions accrued and, therefore, would not have a material adverse
effect on the Companys consolidated statements of income and financial position. Management regularly reviews the timing of the outflows of these provisions. Cash outflows for existing provisions are expected to occur within the next one to
five years, although this is uncertain and depends on the development of the various claims. These outflows are not expected to have a material impact on the Companys cash flows.

20. CONTINGENCIES AND GUARANTEES

The
nature of the Companys legal claims and the provisions recorded for these claims are described in note 17. Although the Company accrues adequate provisions for probable legal claims, it has contingent liabilities relating to reported legal
incidents that, based on current known facts, are not probable to result in future cash outflows. The Company is monitoring these incidents and will accrue no provision until further information results in a situation in which the criteria required
to record a provision is met. Due to the nature of these incidents, such as the range of possible outcomes and the possibility of litigation, it is not practicable for management to estimate the financial effects of these incidents, the amount and
timing of future outflows, and the possibility of any reimbursement of these outflows.

In the normal course of business, the Company provides
indemnifications and, in very limited circumstances, surety bonds. These are often standard contractual terms and are provided to counterparties in transactions such as purchase and sale contracts for assets or shares, service agreements, and
leasing transactions. The Company also indemnifies its directors and officers against any and all claims or losses reasonably incurred in the performance of their service to the Company to the extent permitted by law. These indemnifications may
require the Company to compensate the counterparty for costs incurred as a result of various events, including changes to or in the interpretation of laws and regulations, or as a result of damages or statutory sanctions that may be suffered by the
counterparty as a consequence of the transaction. The terms of these indemnifications will vary based on the contract, the nature of which prevents the Company from making a reasonable estimate of the maximum potential amount that it could be
required to pay to counterparties. The Company carries liability insurance, subject to certain deductibles and policy limits, that provides protection against certain insurable indemnifications. Historically, the Company has not made any material
payments under such indemnifications, and no amounts have been accrued in the consolidated financial statements with respect to these indemnifications.

Common shares

During 2015, the Company filed a Normal Course Issuer
Bid with the Toronto Stock Exchange, which enables it to purchase up to 3,774,179 common shares during the period of November 10, 2015, to November 9, 2016. No common shares were repurchased for cancellation in 2015 pursuant to this Normal
Course Issuer Bid.

During 2015, the Company recognized a share-based compensation expense of $11,200,000 (2014  $7,659,000) in administrative and
marketing expenses in the consolidated statements of income. Of the amount expensed, $5,238,000 (2014  $4,659,000) related to the fair value of options granted and $5,962,000 (2014  $3,000,000) related to the cash-settled share-based
compensation (deferred share units (DSUs), restricted share units (RSUs), and performance share units (PSUs)).

The fair value of options granted was
reflected through contributed surplus, and the cash-settled share-based compensation was reflected through other liabilities. Upon the exercise of share options, for which a share-based compensation expense has been recognized, the cash paid,
together with the related portion of contributed surplus, is credited to share capital.

The fair value of options granted is determined at the date of grant using the Black-Scholes option-pricing
model. The model was developed to use when estimating the fair value of traded options that have no vesting restrictions and are fully transferable. Option valuation models require the input of highly subjective assumptions.

In 2015, the Company granted 965,064 (2014  803,926) share options. The estimated fair value of options granted at the share market price on the grant
date was $5.86 (2014  $6.93) and was determined using the weighted average assumptions indicated below:



|                                                    |  |      |       |  |      |  |       |

The expected volatility was based on the historical volatility of the Companys shares over a period commensurate with
the expected hold period of the share options. The risk-free interest rate for the expected hold period of the options was based on the yield available on government bonds, with an approximate equivalent remaining term at the time of the grant.
Historical data was used to estimate the expected hold period before exercising the options. The options have a contractual life of seven years.

A
summary of the status of the Companys non-vested options as of December 31, 2015, and of changes in the year are as follows:

As at December 31, 2015, 1,722,237 (2014  1,577,150) options remained unvested. As at December 31, 2015, a
total compensation cost of $3,501,000 (2014  $3,497,000) relating to the Companys share option plans remained unrecognized. This cost is expected to be recognized over a weighted average period of 0.86 years (2014  0.84 years).

b) Restricted share units

Under the Companys restricted
share unit plan, senior vice presidents (SVPs) may receive RSUs. An RSU is equal to one common share. The SVPs may be granted an allotment of these units annually; after two years, they receive a cash payment equivalent to the weighted-by-volume
average of the closing price of the Companys common shares for the last 10 trading days before the units release date. The RSUs vest on their grant date since the SVPs are not required to complete a specified period of service. The units
are recorded at fair value. RSUs are adjusted for dividends as they arise, based on the number of units outstanding on the record date.

During 2015, 494
RSUs were issued (2014  38,523) and 50,535 RSUs were paid at an intrinsic value of $1,647,000 (2014  57,415 units were paid at an intrinsic value of $1,914,000). At December 31, 2015, 38,450 RSUs were outstanding at the fair value
of $1,335,000 (2014  88,491 units were outstanding at the fair value of $2,774,000).

c) Performance share units

Under the Companys long-term incentive plan, certain members of the senior leadership teams, including the chief executive officer (CEO), may be granted
PSUs. These units are adjusted for dividends as they arise, based on the number of units held on the record date. PSUs vest upon completing a three-year service condition that starts on the grant date. The number of units that vest is subject to a
percentage that can range from 0% to 200%, depending on achieving two equally weighted three-year performance objectives based on net income growth and return on equity. For units that vest, unit holders receive a cash payment based on the closing
price of the Companys common shares on the third anniversary date of issue. The fair value of these units is expensed over their three-year vesting period.

During 2015, 197,370 PSUs were issued (2014  156,800). In addition, during 2015, 5,064 units were forfeited (2014  1,063). At December 31,
2015, 348,043 PSUs were outstanding at the fair value of $9,962,000 (2014  155,737 units were outstanding at the fair value of $7,795,000).

d) Deferred
share units

The Company also has a DSU plan; directors of the board may receive DSUs. A DSU is equal to one common share. Before 2014, the CEO could
also receive DSUs. These units vest on their grant date and are paid in cash to the CEO and directors of the board on their death or retirement, or in the case of the CEO, in cash on termination. They are valued at the weighted-by-volume average of
the closing market price of the Companys common shares for the last 10 trading days of the month of death, retirement, or termination. These units are recorded at fair value and are adjusted for dividends as they arise, based on the number of
units outstanding on the record date.

During 2015, 57,073 DSUs were issued (2014  55,698). At December 31, 2015, 476,777 DSUs were outstanding
at the fair value of $16,550,000 (2014  419,704 units were outstanding at the fair value of $13,157,000).

22. FAIR VALUE
MEASUREMENTS

All financial instruments carried at fair value are categorized into one of the following three categories:



| |  |  | Level 1  quoted market prices in active markets for identical assets or liabilities at the measurement date
| | - |  | ------------------------------------------------------------------------------------------------------------



| |  |  | Level 2  observable inputs other than quoted prices included within level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical assets or liabilities that are
not active, or other inputs that are observable directly or indirectly
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3  unobservable inputs for the assets and liabilities that reflect the reporting entitys own assumptions and are not based on observable market data
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------

When forming estimates, the Company uses the most observable inputs available for valuation purposes. If a fair value measurement reflects inputs of different
levels within the hierarchy, the financial instrument is categorized based on the lowest level of significant input.

When determining fair value, the
Company considers the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability. The Company measures certain financial assets at fair value on a
recurring basis. During 2015, no change was made to the method of determining fair value.

For financial instruments recognized at fair value on a
recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by reassessing categorizations at the end of each reporting period. During the year ended December 31, 2015, no transfers were made between
levels 1 and 2 fair value measurements.

Investments held for self-insured liabilities consist of government and corporate bonds, equity securities, and term deposits.
Fair value of equities is determined using the reported net asset value per share of the investment funds. The funds derive their value from the observable quoted prices of the equities owned that are traded in an active market. Fair value of bonds
is determined using observable prices of debt with characteristics and maturities that are similar to the bonds being valued.

The following table
summarizes the Companys fair value hierarchy for those liabilities that were not measured at fair value but were disclosed at fair value on a recurring basis as at December 31, 2015:

The fair values of notes payable and senior secured notes are determined by calculating the present value of future payments
using observable benchmark interest rates and credit spreads for debt with similar characteristics and maturities.

23. FINANCIAL
INSTRUMENTS

Credit risk

Credit risk is the risk of
financial loss to the Company if a counterparty to a financial instrument fails to meet its contractual obligation. Financial instruments that subject the Company to credit risk consist primarily of cash and cash equivalents, cash in escrow, other
financial assets, and trade and other receivables.

The Companys maximum amount of credit risk exposure is limited to the carrying amount of these
financial instruments, which is $785,795,000 at December 31, 2015 (2014  $709,207,000).

---

The Company limits its exposure to credit risk by placing its cash and cash equivalents in and entering into
derivative agreements with high-quality credit institutions. Investments held for self-insured liabilities include bonds, equities, and term deposits. The risk associated with bonds, equities, and term deposits is mitigated by the overall quality
and mix of the Companys investment portfolio.

The Company mitigates the risk associated with trade and other receivables and holdbacks on long-term
contracts by providing services to diverse clients in various industries and sectors of the economy. The Company does not concentrate its credit risk in any particular client, industry, or economic or geographic sector. In addition, management
reviews trade and other receivables past due on an ongoing basis to identify matters that could potentially delay the collection of funds at an early stage. The Company monitors trade receivables to an internal target of days of revenue in trade
receivables, which at December 31, 2015, was 68 days (2014  59 days).

Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet obligations associated with its financial liabilities as they fall due. The Company meets
its liquidity needs through a variety of sources, including cash generated from operations, long- and short-term borrowings from its $350 million revolving credit facility and senior secured notes, and the issuance of common shares. The unused
capacity of the credit facility at December 31, 2015, was $252,113,000 (2014  $281,875,000). The Company believes that it has sufficient resources to meet its obligations associated with its financial liabilities. Liquidity risk is
managed according to the Companys internal guideline of maintaining a net debt to EBITDA ratio of less than 2.5 (note 24).

The timing of
undiscounted cash outflows relating to financial liabilities is outlined in the table below:



|                                   |  |         |         |  |                   |  |         |            |  |  |                |  |  |  |       |

In addition to the financial liabilities listed in the table, the Company will pay interest on the bank loan and senior
secured notes outstanding in future periods. Further information on long-term debt is included in note 16.

Interest rate risk

Interest rate risk is the risk that the fair value of the future cash flows of a financial instrument will fluctuate because of changes in market rates of
interest. The Company is subject to interest rate cash flow risk to the extent that its revolving credit facility is based on floating rates of interest. The Company is also subject to interest rate pricing risk to the extent that its investments
held for self-insured liabilities include fixed-rate government bonds, corporate bonds, and term deposits.

If the interest rate on the Companys
revolving credit facility balance at December 31, 2015, was 0.5% higher, with all other variables held constant, net income would have decreased by $358,000. If it was 0.5% lower, an equal and opposite impact on net income would have occurred.
The Company has the flexibility to partly mitigate its exposure to interest rate changes by maintaining a mix of both fixed- and floating-rate debt. The Companys senior secured notes have fixed interest rates; therefore, interest rate
fluctuations would have no impact on the interest payments for the senior secured notes.

---

Foreign exchange risk

Foreign exchange risk is the risk that the fair value of the future cash flows of a financial instrument will fluctuate because of changes in foreign exchange
rates. Foreign exchange gains or losses in net income arise on the translation of foreign currencydenominated assets and liabilities (such as trade and other receivables, trade and other payables, and long-term debt) held in the Companys
Canadian operations and non-US-based foreign subsidiaries. The Company minimizes its exposure to foreign exchange fluctuations on these items by matching foreign currency assets with foreign currency liabilities and, when appropriate, by entering
into forward contracts to buy or sell US dollars and British pounds in exchange for Canadian dollars.

If exchange rates were $0.01 lower at
December 31, 2015, with all other variables held constant, net income would have decreased by $18,000. If they were $0.01 higher, an equal and opposite impact on net income would have occurred.

Foreign exchange fluctuations may also arise on the translation of the Companys US-based subsidiaries or other foreign subsidiaries, where the
functional currency is different from the Canadian dollar, and are recorded in other comprehensive income. The Company does not hedge for this foreign exchange risk.

Price risk

The Companys investments held for self-insured
liabilities are exposed to price risk arising from changes in the market values of the equity funds. This risk is mitigated because the portfolio of equity funds is monitored regularly and is appropriately diversified. A 1.0% increase in equity
prices would have increased the Companys comprehensive income by $284,000. A 1.0% decrease would have had an equal and opposite impact on comprehensive income.

24. CAPITAL MANAGEMENT

The
Companys objective when managing capital is to provide sufficient capacity to cover normal operating and capital expenditures, acquisition growth, and payment of dividends, while maintaining an adequate return for shareholders. The Company
defines its capital as the aggregate of long-term debt (including the current portion) and shareholders equity.

The Company manages its capital
structure to maintain the flexibility to adjust to changes in economic conditions and acquisition growth and to respond to interest rate, foreign exchange, credit, and other risks. To maintain or adjust its capital structure, the Company may
purchase shares for cancellation pursuant to Normal Course Issuer Bids, issue new shares, or raise or retire debt.

The Company periodically monitors
capital by maintaining the following ratio targets:



| |  |  | Net debt to EBITDA ratio below 2.5
| | - |  | ----------------------------------



| |  |  | Return on equity (ROE) at or above 14%
| | - |  | --------------------------------------

These targets are established annually and monitored quarterly. Targets
for 2015 are the same as for 2014.

Net debt to EBITDA ratio, a non-IFRS measure, is calculated as the sum of (1) long-term debt, including current
portion, plus bank indebtedness, less cash and cash equivalents and cash in escrow, divided by (2) EBITDA, calculated as income before income taxes, net interest expense, amortization of intangible assets, depreciation of property and
equipment, and goodwill and intangible asset impairment. The Companys net debt to EBITDA ratio was 0.94 at December 31, 2015 (2014  0.53), calculated on a trailing four-quarter basis. Going forward, there may be occasions when the
Company exceeds its target by completing acquisitions that increase its debt level above the target for a period of time.

ROE, a non-IFRS measure, is
calculated as net income for the last four quarters, divided by average shareholders equity over each of those quarters. The Companys ROE was 12.9% for the year ended December 31, 2015 (2014  16.8%). The Company did not meet
its ROE target since 2015 net income did not increase at historical levels because of challenges in the energy and resource industry and shareholders equity was impacted by an increase in the exchange difference on the translation of the
Companys foreign operations.

The Company is subject to restrictive covenants related to its $350 million revolving credit facility and its
senior secured notes that are measured quarterly. These covenants include, but are not limited to, consolidated debt to EBITDA and EBITDAR to consolidated debt service ratio (non-IFRS measures). EBITDAR is calculated as EBITDA, plus building rental
obligations net of common area costs, taxes, charges, and levies. Failure to meet the terms of one or more of these covenants may constitute a default, potentially resulting in accelerating the repayment of the debt obligation. The Company was in
compliance with the covenants under these agreements as at and throughout the year ended December 31, 2015.

25. INCOME TAXES

The effective income tax rate in the consolidated statements of income differs from statutory Canadian tax rates as a result of the following:

At December 31, 2015, except as noted below, all loss carryforwards available to reduce the taxable income of Canadian,
US, and foreign subsidiaries were recognized in the consolidated financial statements. The Company has unrecognized federal loss carryforwards of approximately $8,044,000 (US$5,812,000) (2014  $1,027,000 (US$885,000)) that are available to
reduce the taxable income of certain US subsidiaries and that expire at varying times over the next 20 years. The Company also has unrecognized loss carryforwards of approximately $8,840,000 (2014  $8,946,000) and no recognized loss
carryforwards that are available to reduce the taxable income of certain other foreign subsidiaries.

Comparative figures for deferred tax assets and
liabilities have been reclassified to confirm to the presentation adopted for the current year. They were offset if a legally enforceable right exists to offset and the deferred taxes relate to the same taxable entity and same taxation authority.

Structured entities

As
at December 31, 2015, the Company has management agreements in place with several entities to provide various services, including architecture, engineering, planning, and project management. These entities have been designed so that voting
rights are not the dominant factor in deciding who controls the entity. Each entity has a management agreement in place that provides the Company with control over the relevant activities of the entity where it has been assessed that the Company is
exposed to variable returns of the entity and can use its power to influence the variable returns. The Company receives a management fee generally equal to the net income of the entities and has an obligation regarding the liabilities and losses of
the entities. Based on these facts and circumstances, management determined that the Company controls these entities, and they are consolidated in the Companys consolidated financial statements. The Company does not have any unconsolidated
structured entities.

The following is a list of the structured entities that are consolidated in the Companys financial statements.

32. SEGMENTED INFORMATION

The Company provides comprehensive professional services in the area of infrastructure and facilities throughout North America and internationally. It
considers the basis on which it is organized, including geographic areas and service offerings, to identify its reportable segments. Operating segments of the Company are defined as components of the Company for which separate financial information
is available and are evaluated regularly by the chief operating decision maker when allocating resources and assessing performance. The chief operating decision maker is the CEO of the Company, and the Companys operating segments are based on
its regional geographic areas.

The Company has three operating segmentsCanada, the United States, and Internationalwhich are aggregated into
the consulting services reportable segment. Canada and the United States are combined into a single reportable segment because each segment provides comparable services and uses similar methods to provide the services. Also, these operating segments
have similar long-term economic performance, nature and type of labor, customer industries, and nature of the regulatory environment. As well, they have similar economic characteristics, such as historical and long-term gross margins and operating,
financing, and underlying currency risks. The International operating segment does not meet the size quantitative thresholds of IFRS 8, and therefore is not reported separately. The International operating segment was combined into consulting
services because it is not material.
