Annual Information Form







FEBRUARY 22, 2017

Cautionary Note Regarding Forward-Looking
Statements

Our public communications often include written or verbal forward-looking statements within the meaning of the US Private
Securities Litigation Reform Act of 1995 safe harbor provisions and forward-looking information within the meaning of applicable Canadian securities laws (collectively, forward-looking statements). Forward-looking
statements are disclosures regarding possible events, conditions, or results of operations that are based on assumptions about future economic conditions or courses of action and include future-oriented financial information.

Statements of this type are contained and incorporated by reference in this Annual Information Form (AIF) and include



| |  |  | The discussion of the expected results of our organizational realignment in the General Development of the Business section in this AIF.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Our beliefs about our risk management strategy and our ability to compete effectively in the Description of the Business section in this AIF.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The discussion of our goals, our key performance drivers, and our annual and long-term targets and expectations for our reportable segments, which can be found in our Managements Discussion and Analysis (MD&A)
section of our Annual Report for the year ended December 31, 2016. Refer to the following sections: Core Business and Strategy, Key Performance Drivers and Capabilities, and the Results (under the Liquidity and Capital Resources subsections)
and Outlook sections (incorporated by reference in this AIF and filed under our profile on SEDAR at www.sedar.com and on EDGAR as an exhibit to our Form 40-F at www.sec.gov).
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Forward-looking statements may involve, but are not limited to, comments with respect to our objectives for 2017 and beyond, strategies or future actions,
dividend policy, targets, expectations for our financial condition or share price, and results of our outlook for our operations.

The purpose of this
information is to describe managements expectations and targets for measuring our success and to assist our shareholders to understand our financial position as at and for the periods ended on the dates presented in this AIF. We caution
readers that this information may not be appropriate for other purposes.

By their nature, forward-looking statements require us to make assumptions and
are subject to inherent risks and uncertainties. There is significant risk that predictions, forecasts, conclusions, projections, and other forward-looking statements will not prove to be accurate. We caution readers of this AIF not to place undue
reliance on our forward-looking statements since a number of factors could cause actual future results, conditions, actions, or events to differ materially from the targets, expectations, estimates, or intentions expressed in these forward-looking
statements.

The following factorsamong others listed under the Key Performance Drivers and Capabilities section of our MD&A for the year ended
December 31, 2016 (incorporated by reference in this AIF and filed under our profile on SEDAR at www.sedar.com and on EDGAR as an exhibit to our Form 40-F at www.sec.gov)could cause our actual
results to differ materially from those projected in our forward-looking statements:



| |  |  | Global capital market activities
| | - |  | --------------------------------



| |  |  | Fluctuations in interest rates or currency values
| | - |  | -------------------------------------------------



| |  |  | Fluctuations in commodity prices
| | - |  | --------------------------------



| |  |  | Effects of war or terrorist activities in the geographic areas in which we operate
| | - |  | ----------------------------------------------------------------------------------



Stantec
Inc.        3



---

| |  |  | Effects of disease or illness on local, national, or international economies
| | - |  | ----------------------------------------------------------------------------



| |  |  | Effects of disruptions to public infrastructure, such as transportation, communications, power, and water
| | - |  | ---------------------------------------------------------------------------------------------------------



| |  |  | Global economic or political conditions
| | - |  | ---------------------------------------



| |  |  | Regulatory or statutory developments
| | - |  | ------------------------------------



| |  |  | Effects of competition in the geographic or business areas in which we operate
| | - |  | ------------------------------------------------------------------------------



| |  |  | Actions of management
| | - |  | ---------------------



| |  |  | Technological changes
| | - |  | ---------------------

Many of these factors are beyond our control and have effects that are difficult to
predict.

Assumptions about the performance of the Canadian, US, and global economies in 2017 and how such performance will affect our business are
material factors that we consider when determining our forward-looking statements. These assumptions are discussed in the Outlook section of our MD&A for the year ended December 31, 2016 (incorporated by reference in this AIF and filed
under our profile on SEDAR at www.sedar.com and on EDGAR as an exhibit to our Form 40-F at www.sec.gov).

For
additional information regarding material and known risks and assumptions, see pages M-68 to M-78 and M-80 to M-81 of our MD&A, and for further information about our key performance drivers, see pages M-11 to M-19. Our MD&A for the year
ended December 31, 2016 is incorporated by reference in this AIF and filed on SEDAR at www.sedar.com and on EDGAR as an exhibit to our Form 40-F at www.sec.gov.

We caution that various factors, including those discussed in our MD&A, could adversely affect our results. Investors and others should carefully consider
these factorsas well as other uncertainties and potential events and the inherent uncertainty of forward-looking statementswhen relying on these statements to make decisions about our Company.

The forward-looking statements contained in this AIF represent our expectations as at February 22, 2017, and are subject to change after that date.
Except as may be required by law, we do not undertake to update any written or verbal forward-looking statement that we may make from time to time. Our current practice is to evaluate and, where we deem appropriate, provide updates to ranges of
expected performance for 2017. However, subject to legal requirements, we may change this practice at any time at our sole discretion.

General Development of the Business

| |  |

| |  | 

2017

The following information highlights the general development of our business for the current financial year.

ORGANIZATIONAL EVOLUTION

In 2016, we continued the process of
realigning our internal structure to better serve our clients. The acquisition of MWH Global, Inc. and its affiliated and subsidiary companies (MWH) added a world-class design presence in the water sector, including a
top-tier presence in the United States and United Kingdom, and a world-class presence in waterpower and dams. To best leverage this expertise and offer a higher degree of leadership and increased visibility
for clients and employees, effective January 1, 2017, we combined legacy Stantecs Water sector from the Infrastructure business operating unit and MWHs Water businesses into a separate business operating unitWater.

THREE-YEAR HISTORY

Highlights of Stantecs general
development over the past three years follow.

OFFICER AND DIRECTOR CHANGES

As Stantecs chief operating officer (COO), Richard Allen, prepared to retire in 2016, the COOs roles and responsibilities were divided into two
positions to better meet the needs of Stantecs diverse business model. Effective January 1, 2016:



| |  |  | Scott Murray was appointed chief operating officer (COO)  this role oversees Company operations, including health and safety, regional operations, and our Project Delivery Office
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Valentino DiManno was appointed chief business officer (CBO)  this newly created role oversees all business operating units, account management, client development, and quality management
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Reporting to the chief executive officer (CEO), the COO and CBO have equal leadership responsibility and work together to manage all aspects of Stantecs
business. We believe that these balanced roles further improve and strengthen our balanced leadership model.

In addition, David Emerson did not stand for
re-election as a director at our annual general meeting of shareholders held on May 12, 2016, and thus his service as a director of Stantec ended on that date. Effective November 9, 2016, Marie-Lucie
Morin was appointed to Stantecs board of directors.

RENEWAL OF NORMAL COURSE ISSUER BID

On November 10, 2016, we announced that the renewal of our Normal Course Issuer Bid (NCIB) was filed with and approved by the Toronto Stock Exchange
(TSX). Pursuant to the 2016 NCIB, Stantec may purchase up to 3,418,357 common shares, representing approximately 3% of Stantecs 113,945,237 issued and outstanding common shares as of November 2, 2016. Purchases were permitted to commence
on November 14, 2016, and terminate no later than November 13, 2017. Except for block purchases permitted by the TSX, the number of shares purchased per day will not exceed 58,371 or approximately 25% of the average daily trading volume
for the six full calendar months prior to October 31, 2016. During 2016, 572,825 common shares were repurchased for cancellation at a cost of $18.2 million.

ORGANIZATIONAL EVOLUTION

Continuing the process of realigning our
internal structure to better serve our clients, we recognized that although Environmental Services and Energy & Resources share many similar clients, their businesses are in fact different. To provide them with a higher degree of leadership
and better visibility within the Company for the services they perform, effective August 2016, we made the Environmental Services group a fourth business operating unit. Our Mining, Oil & Gas, and Power sectors remain within the
Energy & Resources business operating unit.

ADDITION OF CONSTRUCTION SERVICES

As a result of the MWH acquisition, our business model expanded to include Construction Services, where we provide construction management and project delivery
at-risk services, primarily on water-related projects to key long-term clients in the United States and United Kingdom. For further information regarding Construction Services, see the Description of the
Business section in this AIF.

FINANCING

We financed the MWH
acquisition through the net proceeds of a public offering of 17,360,000 subscription receipts sold for $30.25 each for gross proceeds of $525.1 million, where each subscription receipt represented the right of the holder to receive one common
share upon closing of the MWH acquisition, and funds drawn from the New Credit Facilities (described below).

The public offering of subscription receipts

2014

ORGANIZATIONAL REALIGNMENT

Effective January 1, 2014, we
realigned our organizational structure, changing from practice area units to three business operating units: Buildings, Energy & Resources, and Infrastructure. We did not change the foundation of our matrix-based leadership structure; we
simply realigned it. The realignment was based on the belief that it would create greater accountability for our leadership team, result in more focused growth, and help us to better support our clients and maintain the core elements of our
strategy.

OFFICER AND DIRECTOR CHANGES

During 2014, we also
realigned our senior leadership team into two levels: the Executive Vice President Team (EVPT) and the Executive Leadership Team (ELT). The EVPT consists of our CEO, chief financial officer (CFO), COO, and the following executive vice presidents
(EVPs), appointed in 2014:



|                                       |  |                                              |  |                                        
|-------------------------------------- |  | -------------------------------------------- |  | ---------------------------------------
|      Paul Allen
     
 Carl Clayton |  |       Valentino DiManno
      Scott Murray |  |       Eric Nielsen
      Stanis
Smith

The ELT, consisting of senior vice presidents and certain vice presidents, oversees Stantecs overall performance,
including developing and monitoring our business plan, monitoring financial performance and risks, approving policies and procedures, and overseeing acquisitions and divestitures.

Our EVPs are specifically responsible for the performance of our regional operating units and business operating units.

SHARE SPLIT

On September 4, 2014, our board of directors
declared a two-for-one share split to be effected by way of a share dividend. Shareholders of record as of the close of business on October 31, 2014, were entitled
to the share dividend on the November 14, 2014 payment date.

Description of the Business

| |  | 
| |  | 
| | 
| |  | 

Stantec collaborates across disciplines and industries to bring buildings, energy and resources, environmental, and
infrastructure projects to life. Our workengineering, architecture, interior design, landscape architecture, surveying, environmental sciences, construction services, project management, and project economics, from initial project concept and
planning through to design, construction, commissioning, maintenance, decommissioning, and remediationbegins at the intersection of community, creativity, and client relationships. With a long-term commitment to the people and places we serve,
Stantec has the unique ability to connect to projects on a personal level and advance the quality of life in communities across the globe.

Our business
objective is to be a top 10 global design firm.

Our business model is a key element of our strategy. It is based on providing services across diverse
geographic regions, business operating units, specializations, and all phases of the infrastructure and facilities project life cycleplanning, design, construction, commissioning, maintenance, decommissioning, and remediation.

Because of the diversity of our model, we can generally adapt to changes in market conditions by offsetting decreased demand for services in one business
operating unit or geographic location with increased demand in another. We believe this strategy allows us to mitigate risk while continuing to increase our revenue and earnings. Also, it allows us to provide services to many clients rather than
rely on a few large projects for our revenue; we work on tens of thousands of projects, for thousands of clients, in hundreds of locations.

Our chief
operating decision maker (CEO) assesses our Companys performance based on financial information available from our operating segments. In 2015 and the first quarter of 2016, our Company had one reportable segment, Consulting Services, which
was an aggregate of our previous operating segments (regional geographic areas).

As a result of the MWH acquisition and effective the second quarter of
2016, our reportable segments (in accordance with IFRS) are based on our two primary service offerings, Consulting Services and Construction Services, and our regional geographic areas. The Company now has four operating and reportable segments:
Consulting Services  Canada, Consulting Services  United States, Consulting Services  Global, and Construction Services.

The following
table illustrates the breakdown of gross revenue for our reportable segments in 2015 and 2016. All amounts in this AIF are in Canadian dollars unless otherwise noted.

Before acquiring MWH, we had international offices in the Middle East, the United Kingdom, and the Caribbean. MWH
had a global presence in the United Kingdom, Australia, New Zealand, South and Central America, Europe, and the Middle East. Since the MWH acquisition, our Consulting Services business continues to operate as three regional operating
segmentsCanada, the United States, and Global (formerly International); the Construction Services business operates as one segment.

In 2016, we
earned 58%of our total gross revenue (including revenue from both Consulting Services and Construction Services) in the United States, 27% in Canada, and 15% in global markets. For Consulting Services,57% of our gross
revenue was earned inthe United States, 32% in Canada, and 11% in global markets. For Construction Services, 63% was earned in the United States and 37% in global markets.

For additional information regarding our core business and strategy, see our MD&A for the year ended December 31, 2016, pages M-4 to M-19 (incorporated by reference in this AIF and filed on SEDAR at www.sedar.com and on EDGAR as an exhibit to our Form 40-F at
www.sec.gov).

Research and Development

We generally conduct research and development for a clients specific project requirements. Most research and development is conducted in the areas of
infrastructure evaluation and management systems, hydraulic modeling of water and wastewater systems, wastewater treatment, and pavement evaluation and management systems.

Competitive Conditions

We work in
highly competitive markets and have numerous competitors for all of our services. The number and identity of competitors vary widely with the type of service we provide. For small to midsized projects, we compete with many engineering, architecture,
construction management, and other professional consulting firms. For larger projects, we have fewer but still many competitors; however, some competitors may have greater financial and other resources than we have. Although we compete with large
private and public companies in certain geographic locations, our primary competitors are small to midsized privately held regional firms.

We believe
that our operating structure, our operating philosophy, our enterprise systems, and the diversity and scope of our professional services differentiate us from other engineering, architecture, construction management, and professional consulting
firms.

The main competitive advantages that we have in the services we offer are reputation, experience, breadth and quality of services, technical
proficiency, local offices, competitive total project fees, and integrated service delivery. Our successful track record of acquiring and integrating firms also provides us with a competitive advantage. Given the expanding demand for the services we
provide, additional competitors will likely emerge. Even with this increased competition, we believe that we will compete effectively because of our strengths and expertise in engineering, architecture, construction management, and related
professional services, as well as our successful track record of service delivery.

Services

We serve many diverse clients in the private and public sectors and aim to establish ongoing relationships with clients that are likely to produce repeat
business. We work on tens of thousands of projects, for thousands of clients, in hundreds of locations, ensuring that we do not rely on a few large projects for our revenue.

In Consulting Services, we provide knowledge-based solutions through value-added professional consulting services in engineering, architecture, interior
design, landscape architecture, surveying, environmental sciences, project management, and project economics in the areas of infrastructure and facilities, principally under
fee-for-service agreements with clients.

---

In Construction Services, we provide construction management and project delivery
at-risk services, primarily on water-related projects to key long-term clients in the United States and the United Kingdom. We offer
start-to-finish construction capabilities to municipal, utility, federal, and industrial clients, including commissioning and
start-up services. Separate from project delivery, we also provide construction management and professional supervision services. Construction Services revenue is derived primarily from cost-reimbursable,
guaranteed-maximum price contracts and fixed-price contracts.

We offer a range of pricing structures to our clients but usually provide our services
based on a fixed or variable-fee contract (with a ceiling) or a time-and-material contract (without a stated ceiling). Most
assignments are acquired because of our expertise and contacts; others are obtained through a competitive bidding process.

Employees

As at December 31, 2016, we had approximately 22,000 staff, including professionals, technologists and technicians, and support
personnel.

We are a knowledge-based organization, always seeking talented and skilled professionals for all of our specialized services. We use various
recruitment strategies to address staffing needs: an employee referral bonus program, website job postings, career fairs, student programs, and opportunities to transfer to other office locations.

Social and Environmental Policies

Stantec is committed to continual improvements in all aspects of its business, including health and safety and the environment. Accordingly, Stantec has
implemented two formal systems that impact these areasthe Occupational Health & Safety Management System (OHSMS) and the Environmental Management System (EMS)across Stantecs legacy operations. These systems are part of our
Company-wide Integrated Management System (IMS). In addition, we will focus on combining the best of Stantecs systems and processes with those acquired through the MWH transaction.

OCCUPATIONAL HEALTH & SAFETY MANAGEMENT SYSTEM

In 2014,
Stantec successfully developed and implemented the Occupational Health & Safety Management System (OHSMS), which received external third-party certification under the consensus-based international standard for occupational health and
safetyOHSAS 18001:2007.

The objectives of our certified OHSMS are to



| |  |  | Protect our employees from injury and prevent property loss and environmental damage by aligning work processes, systems, and behaviors so our employees have the necessary guidance and knowledge to complete every task
safely, every time
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Comply with applicable regulatory requirements and our Health, Safety & Environment (HSE) Policy
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | Meet client requirements and expectations
| | - |  | -----------------------------------------

To address our Companys diversity, the HSE team develops core
health, safety, and environment practices that can be implemented Company-wide yet are adaptable to suit the needs of any region, business operating unit, client, or project.

Stantec tracks lagging indicators (e.g., workers compensation costs, total recordable injury rates) and leading indicators (e.g., site visits, file
reviews, safety meetings, worksite inspections) to gauge the effectiveness of the OHSMS.

Internal practice auditors from our Practice Services team
conduct internal practice audits to assess compliance and identify program strengths and opportunities for improving health and safety performance. Independent (third-party) audits of the OHSMS are conducted yearly. As well, external audits are
conducted in many provinces in Canada to maintain external certifications (e.g., a certificate of recognition) that meet provincial standards.

HEALTH, SAFETY & ENVIRONMENT POLICY

We are committed to providing and maintaining a healthy, and safe workplace and to responsibly managing all of the environmental aspects of our business.

Our core Company values guide us in all that we do. The way we treat our people, our clients, and our neighbors reflects who we are, what we believe in, and
how we do our work. At Stantec, we believe in doing what is right, which includes sending our people home injury-free every day.

Stantec strives to



| |  |  | Identify, assess, and manage the health, safety, and environmental hazards and risks our employees are exposed to
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Minimize the environmental aspects and impacts associated with the services and products we provide

| | - |  | --------------------------------------------------------------------------



| |  |  | Foster a culture in which all employees, partners, contractors, and subconsultants share a commitment to health, safety, and the environment
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------

Everyone working for Stantec is responsible and accountable for Stantecs health, safety, and environmental performance. Management, supervisors,
employees, contractors, and subconsultants are expected to understand their roles and responsibilities, as outlined in the practices of the OHSMS and in our HSE Policy.

ENVIRONMENTAL MANAGEMENT SYSTEM

To support Stantecs
Sustainability Policywhich promotes improving our environmental performance and reducing our environmental footprintwe developed and implemented a formal Environmental Management System (EMS). Our EMS is registered to the International
Organization for Standardizations 14001:2004 environmental management standard, which is recognized internationally as the consensus environmental standard. Independent (third-party) audits of the EMS are conducted annually.

SUSTAINABILITY POLICY

Stantec is committed to being a leader and
model of sustainability by doing business in a way that meets the needs of the present while contributing to an environmentally, socially, and economically sustainable future. This commitmentat the heart of how we operate and deliver solutions
to our clientsis vital to our long-term success in achieving our vision.

We focus our efforts where we believe we can have a significant impact, as
follows:

Global
Operations

In 2016, Stantec remained active internationally; gross revenue from Global operations was approximately $415.6 million.

Following the MWH acquisition, we perform work and have permanent offices located in the United Kingdom, Australia, New Zealand, South and Central America,
Europe, the Middle East, and the Caribbean.

For Stantecs legacy operations, all projects are reviewed in accordance with Stantecs Project
Management Framework, which includes following legal, financial, and technical processes, among other things. As well, each in-country project is examined to ensure that any health, safety, and security or
political risks are acceptable. All major projects are subject to major project reviews, when applicable, and all projects have an executive leadership sponsor. In addition, we will focus on combining the best of Stantecs systems and processes
with those acquired through the MWH transaction.

Risk Factors





For a review of the risks pertaining to our Company, please refer to our MD&A for the year ended December 31, 2016, pages M-68 to M-78 (incorporated by reference in this AIF and filed on SEDAR at www.sedar.com and on EDGAR as an exhibit to our

Dividends





On February 15, 2012, Stantecs board of directors approved our Dividend Policy and concurrently declared Stantecs first quarterly dividend.
Pursuant to our Dividend Policy, the Company anticipates it will pay a quarterly dividend to shareholders of record on the last business day of each quarter with actual payment to be made to those shareholders on or about the 15th day of the
following month.

Since the adoption of our Dividend Policy, we have paid quarterly dividends on our common shares. While the
Company aims to declare and pay a dividend quarterly, our Dividend Policy is at the sole discretion of our board of directors and may vary depending on a variety of factors, including prevailing economic and market conditions, the Companys
earnings, the financial requirements for the Companys operations, the business strategy of the Company, the provisions of applicable law, and any other factors that our board of directors considers relevant. Therefore, Stantec cannot guarantee
that our Dividend Policy will be maintained.

On September 4, 2014, our board of directors declared a two-for-one share split to be effected by way of a share dividend. Shareholders of record as of the close of business on October 31, 2014, were entitled to the share dividend on the payment date of
November 14, 2014.

The following table outlines cash dividends paid per common share in 2016, 2015, and 2014. Dividends paid per common share before
the share split have been restated to half of the previously reported amounts to reflect the two-for-one share split described in the previous paragraph.

Description of Capital Structure

| |  |

of common shares. As at December 31, 2016, no preferred shares and 114,081,229 common shares were issued and outstanding.

Preferred
Shares

Preferred shares may be issued in one or more series. The board of directors determines the number of shares and the rights,
privileges, restrictions, and conditions attaching to each series. The holders of the preferred shares as a class are not entitled to receive notice of or to attend any shareholders meeting and are not entitled to vote at any
shareholders meeting, except to approve amendments to the terms of the preferred shares as a class or as required by law.

Each series of preferred
shares will rank pari passu with each of the other series of preferred shares with respect to the entitlement to dividends and distribution of assets in the event of the liquidation, dissolution, or winding up of Stantec. Preferred shares as
a class rank ahead of common shares with respect to entitlement to dividends and distribution of assets in the event of the liquidation, dissolution, or winding up of Stantec.

Common Shares

The holders of common
shares are entitled to receive, as and when declared by our board of directors, dividends in an amount and form that our board of directors may from time to time determine. Holders of common shares are entitled to receive notice of and to attend all
shareholders meetings. They will have one vote for each common share held at all such meetings, unless the meeting is only for holders of another specified class or series of our shares who are entitled to vote separately as a class or series.
