Mott MacDonald has a long and successful history of working in Canada. Wehave contributed to award-winning high-profile projects including Sea-to-Sky Highway, Port Mann/Highway 1 Improvement Project, King Road Grade Separation, and Calgary West LRT. In addition, Mott MacDonald has an important role in infrastructure financing in Canada.

Our business in North America is thriving. With over 2300 staff in 64 US and Canadian cities, Mott MacDonald is delivering pivotal projects in the transport, water, oil and gas sectors, plus projects in education, power, buildings, and infrastructure finance.

We are independent certifier for a CA$2.2 billion 772 bed hospital in Montréal, Québec. We have been appointed by the Centre hospitalier de l'Université de Montréal (CHUM) Hospital Authority for this design, build, finance and maintain project with a concession period of 30 years.

We have undertaken a number of projects on behalf of the P3 Canada Fund – a merit-based program, designed to incentivise the use of public private partnerships (P3) in delivering public infrastructure projects. These include a peer review of costing methodologies for two projects under consideration for investment from the fund and assisting in the development of standardised risk guidance to be used by public sector authorities when applying for P3 funding.

Mott MacDonald was lenders’ technical advisor for three major venues ahead of the Toronto 2015 Pan/Parapan America Games – The Hamilton Soccer Stadium, York University Athletics Stadium and Milton Velodrome. The bundling of three venues in one project agreement required careful provision to ensure lenders were protected if there was a delay to construction at any one of the sites. Mott MacDonald was instrumental in working with the lenders in order to achieve financial close.


We served as owner’s engineer for construction of a new West Line to Calgary’s existing light rail system. Our role encompassed design, schedule development, cost estimating, constructability reviews, risk management, construction monitoring and quality auditing. The project won awards from the Consulting Engineers of Alberta and the Association of Professional Engineers, Geologists and Geophysicists of Alberta.

The Windsor-Essex Parkway is being designed to improve the flow of traffic along a route that is expected to carry 28% of Canada’s trade with the US. Construction started in 2011, and has already generated approximately 12,000 jobs by creating business opportunities, attracting new investment, and supporting existing industry. We served as the lead designer for the project as part of a public private partnership (P3). By streamlining the design and construction of the parkway, we were able to cut $100 million from the estimated cost of the project.

Our buildings team continues to grow, working on a number of significant projects in the country. For Mosaic Stadium in Regina, our design for the city’s new open air stadium will make playing and watching more comfortable – extending the playing season by two months per year. The stadium roof’s design all but eliminates the effects of wind while allowing sun into the stadium, increasing the operating temperature by up to 20°C throughout freezing winters. The design includes provision for a retractable roof in future to allow year-round use.
