STANTEC INC.    ANNUAL INFORMATION FORM

FEBRUARY 20, 2013

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 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 and courses of action and include future-oriented financial information.

Statements of this type are contained and incorporated by reference in this report, including the discussion of our goals in the Core Business and
Strategy section and of our annual and long-term targets and expectations for our regions and practice area units in the Results and Outlook sections of our managements discussion and analysis for the year ended December 31, 2012, which
have been incorporated by reference in this annual information form (as described on page 9), and may be contained in filings with securities regulators or in other communications. Forward-looking statements may involve, but are not limited to,
comments with respect to our objectives for 2013 and beyond, our strategies or future actions, our dividend policy, our targets, our expectations for our financial condition or share price, or the results of our outlook for our operations in order
to describe the management expectations and targets by which we measure our success and to assist our shareholders in understanding our financial position as at and for the periods ended on the dates presented in this report. Readers are cautioned
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 document
not to place undue reliance on its 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, 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
| | - |  | -------------------------------------------------

| |  |  | The effects of war or terrorist activities
| | - |  | ------------------------------------------

| |  |  | The effects of disease or illness on local, national, or international economies
| | - |  | --------------------------------------------------------------------------------

| |  |  | The effects of disruptions to public infrastructure such as transportation, communications, power, or water
| | - |  | -----------------------------------------------------------------------------------------------------------

| |  |  | Global economic or political conditions
| | - |  | ---------------------------------------

| |  |  | Regulatory or statutory developments
| | - |  | ------------------------------------

| |  |  | The effects of competition in the geographic or business areas in which we operate
| | - |  | ----------------------------------------------------------------------------------

| |  |  | The actions of management
| | - |  | -------------------------

| |  |  | Technological changes
| | - |  | ---------------------

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

Assumptions about the performance of the Canadian
and US economies in 2013, and how it will affect our business, are material factors we consider in determining our forward-looking statements and are discussed in the Outlook section of our managements discussion and analysis for the year
ended December 31, 2012, filed on www.sedar.com, and incorporated by reference in this annual information form.

For
additional information regarding material and known risks and assumptions, see the discussion on pages M-57 to M-64 and M-67 to M-68 of our managements discussion and analysis for the year ended December 31, 2012, which is incorporated by
reference in this annual information form.

We caution that different factors, including those discussed in our managements
discussion and analysis and others, 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 with respect to our Company. The forward-looking statements contained herein represent our expectations as of February 20, 2013, and, accordingly, are subject to change after such date. Except
as may be required by law, we do not undertake to update any forward-looking statement, whether written or verbal, that may be made, from time to time, by us or on our behalf. In the case of the ranges of expected performance for

fiscal 2013, it is our current practice to evaluate and, where we deem appropriate, provide updates. However, subject to legal requirements, we may change this practice at any time at our sole
discretion.

DESCRIPTION OF THE BUSINESS

Stantec
provides professional consulting services in planning, engineering, architecture, interior design, landscape architecture, surveying, environmental sciences, project management, and project economics for infrastructure and facilities projects. By
integrating our expertise in these areas across North America and international locations, we are able to provide our clients with a vast number of project solutions. This integrated approach enables us to execute our operating philosophy by
maintaining a world-class level of expertise that we supply to our clients through the strength of our local offices.

We focus on
providing professional consulting services in the infrastructure and facilities market, principally on a fee-for-service basis, while participating in various models of alternative project delivery. By focusing on a multidisciplinary service
delivery, we also support clients throughout the project life cyclefrom the initial conceptualization and financial feasibility to project completion and beyond.

We have one reportable segment under International Financial Reporting Standards (IFRS): consulting services.

The following table illustrates the breakdown of gross revenue for 2012 and 2011 for consulting services:



|                    |  |                             |                        |  |                             |  |                        |

We organize our operations into three main geographic regions, Canada, the United States, and International. In
2012, we earned 58% of our gross revenue in Canada, 38% in the United States and 4% internationally. Our international offices are in the Caribbean, the United Kingdom, the Middle East, and India. For additional information regarding our core
business and strategy, see our 2012 managements discussion and analysis pages M-2 to M-7, which are incorporated by reference herein.

Research
and Development

We generally conduct research and development in the context of 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, pavement evaluation and management systems, and wastewater treatment.

Competitive Conditions

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

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

The principal competitive factors 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. Given the expanding demand for the services we provide, it is
likely that additional competitors will emerge. Notwithstanding this increased competition, we believe that we will retain the ability to compete effectively because of our strengths and expertise in engineering, architecture, and related
professional services and our track record of service delivery.

Services

We serve many diverse clients in both the private and public sectors. We seek to establish ongoing relationships with clients that are likely to
produce repeat business. We are not dependent on any one client or group of clients for our business. No single client or project represents more than 5% of our overall business.

We offer a range of pricing structures to our clients but primarily provide our services based on either a fixed- or variable-fee contract with a
ceiling, or a time-and-material contract without a stated ceiling. We secure our assignments primarily based on our expertise and contacts and sometimes based on a competitive bidding process.

Employees

As at December 31, 2012, we
had approximately 12,700 staff. This total staff number is comprised of approximately 7,300 professionals, 4,000 technologists and technicians, and 1,400 support personnel.

We are a knowledge-based organization and are always seeking talented and skilled professionals in all of our specialized practice areas. Since the supply of qualified candidates is sometimes limited, we use
various recruitment strategies to address staffing needs. Examples of our recruitment strategies include our employee referral bonus program, website job postings, career fairs, student programs, and opportunities to transfer to other office
locations.

Reorganization

In
the first quarter of 2010, we reorganized our corporate structure to make it more efficient, which increased our estimated income tax expense by $6.2 million. The reorganization resulted in a gain for tax purposes; however, this gain did not affect
income taxes payable, since it was used to offset previously recognized US income tax losses.

Effective at the close of business on
December 31, 2011, Stantec Consulting Corporation (SCC), a Delaware corporation, was merged into its affiliate, Stantec Consulting Services Inc. (SCSI), a New York Corporation. SCC was the successor entity of the acquisition of and merger
with SECOR International Incorporated in 2008. The purpose of the merger of SCC and SCSI was to further consolidate and streamline our US operations.

Social and Environmental Policies

Stantecs
Health, Safety & Environment (HSE) Program

Stantec is committed to continual improvement in the area of health and safety
in all aspects of its business. Led by our vice president, People + Practice, the HSE team includes an HSE director, managers for both the United States and Canada, regional coordinators, more than 100 office coordinators, two dedicated
workers compensation claims coordinators, and systems and administrative support staff.

The HSE programs objective is to
protect our employees from injury and to prevent property loss and environmental damage by aligning work processes, systems, and behaviors so that our employees have the necessary guidance and knowledge to complete every task safely, every time. To
achieve this objective, the HSE team develops practices



Page 10



---

and tools that protect employees not only by meeting or exceeding government regulations, but also by striving for best practices.

The foundation of the program is a Hazard Recognition and Control (HRAC) process that enables employees at all levels to establish a healthy and
safe work environment. Projects begin with the development of a Risk Management Strategy form that identifies potential risks associated with the project site. Based on these risks, additional controls may be implemented. For example:



| |  |  | A job safety analysis (JSA) can be completed for identified risks. A JSA breaks down a task into component steps with identification of associated hazards and
precautions.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | A site-specific Health and Safety Plan (HASP) may be prepared for each site. All employees, subcontractors, and visitors to applicable sites are required to
review and adhere to the health and safety guidelines presented in the HASP.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Through these formal strategies, along
with regular last-minute risk assessments, the HRAC process empowers employees to proactively identify hazards, assess risks, eliminate or control risks, and stop work if required in order to prevent injury and illness, environmental and property
damage, and other types of costly business interruptions.

The HSE team also supports the organization by



| |  |  | Maintaining approved health, safety, and environment procedures for many specific work tasks in the form of safe work practices.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------

| |  |  | Providing health, safety, and environment training and education; completing root cause analysis and evaluating lessons learned from recordable injuries and
other incidents.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  |  | Coordinating case management following work-related injuries and illnesses.
| | - |  | ---------------------------------------------------------------------------

Due to the diversity of the Stantec organization, 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 particular region, client, or project.

Our Company HSE program is outlined
in our corporate Health and Safety policy, HSE Program Manual, and Safe Work Practices.

The program is communicated to
employees through a comprehensive communications strategy that includes regular features in our Company magazine, ongoing use of the Companys intranet, eBulletins from senior leadership, office signage, presentations, and workshops. In
addition to tracking lagging indicators (workers compensation costs and total recordable injury rates), we also track leading indicators such as site visits, file reviews, safety meetings, and worksite inspections to further gauge the
effectiveness of the program. The HSE team is able to conduct internal audits to assist in assessing compliance and to identify program strengths and opportunities for improving health and safety performance.

Independent (third-party) audits of the HSE program may also be conducted as necessary to obtain and maintain external certification (e.g., a
Certificate of Recognition). These audits are conducted on a regular basis (often every three years) by an independent auditor. The results of the audits are documented and brought to the attention of the Joint Health and Safety Committee, regional
safety coordinator, local leadership, and the HSE director. The committee monitors corrective action, addresses deficiencies found by the audit, and facilitates preventive action if opportunities are identified. Responsibility for corrective and
preventive action will be assigned and recorded in a Health and Safety Action Plan.

ISO 14001:2004 Registration

In support of Stantecs sustainability policy promoting compliance with applicable environmental regulations and reducing our environmental
footprint, we have developed and implemented a formal environmental management system. The environmental management system is registered to the ISO 14001:2004 environmental management standard, an internationally recognized standard, and is audited
annually by an external auditor. Our ISO 14001:2004 registered environmental management system requires leadership to establish environmental performance objectives, such as the reduction of energy, resource use, and waste, and to formally report on
those objectives within an accountable and transparent framework. Stantec received confirmation of registration on January 20, 2012.

Stantecs 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

International Operations

In 2012, Stantec remained active internationally with gross revenue from international operations of approximately $76.2 million.

We work in country via our permanent offices located in the United Kingdom, the Middle East, India, Panama, Qatar, and Barbados and
manage and support that work from our offices located in the United States or Canada.

All projects are reviewed for compliance with
Stantecs legal, financial, and technical processes. In addition, each in-country project is examined to ensure that any health and safety or political risks are acceptable. All major projects are subject to major project reviews where
applicable and all projects have an executive leadership sponsor.

RISK FACTORS

For a review of the risks pertaining to our Company, refer to our 2012 managements discussion and analysis, pages M-57 to M-64, which is
filed on SEDAR at www.sedar.com and incorporated by reference herein.

DIVIDENDS

On February 15, 2012, Stantecs board of directors approved a dividend policy and started declaring quarterly dividends of $0.15 per
share. For the year ended December 31, 2012, the total amount of dividends declared by the Company was $0.60 per share. While the Company aims to declare and pay a dividend on a quarterly basis, the dividend policy may be changed from time to
time in the sole discretion of the board of directors. Accordingly, there can be no assurances as to the amount or timing of any dividend in the future. In assessing whether to pay a dividend and in determining the amount of the dividend,
the board of directors will consider, among other things, prevailing economic and market conditions, the Companys earnings, financial requirements for the Companys operations, the business strategy of the Company and other factors which
our board of directors considers relevant from time to time.

DESCRIPTION OF CAPITAL STRUCTURE

Our authorized share capital consists of an unlimited number of preferred shares, issuable in series, and an unlimited number of common shares, of
which, at December 31, 2012, no preferred shares and 45,983,894 common shares were issued and are outstanding.

Preferred Shares

The preferred shares may be issued in one or more series, with each series to consist of such number of shares and to have such rights, privileges, restrictions, and conditions as may, before the issue thereof, be
determined by our board of directors. The holders of the preferred shares as a class are not entitled to receive notice of or to attend any meeting of our shareholders and are not entitled to vote at any such 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 other series of preferred shares with respect to the entitlement to dividends or distribution of assets in the
event of the liquidation, dissolution, or winding up of Stantec. The preferred shares as a class rank ahead of the 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 such amount and in such form as our board of directors may from time to time determine. The holders
of the common shares are entitled to receive notice of and to attend all meetings of our shareholders and have one vote for each common share held at all such meetings, except for meetings at which only holders of another specified class or series
of our shares are entitled to vote separately as a class or series. The common shares rank behind the preferred shares with respect to entitlement to dividends and distribution of assets in the event of the liquidation, dissolution, or winding up of
Stantec.

Any proposed services exceeding preapproved cost levels will require specific preapproval by the Audit and Risk Committee.
