Union Station was revitalized to accommodate projected passenger growth while restoring Canada’s most significant Beaux Arts railway station and transforming the landmark into a vibrant transit and retail destination in Toronto, ON.
Challenge
Accommodating projected growth from 60 million passengers annually to 130 million by 2036 required a major expansion within a constrained heritage environment while maintaining uninterrupted transit operations. The project needed to preserve a landmark building that has served as a gateway to Toronto since 1927.
Solution
Our design delivers one of the most technically innovative architecture and engineering solutions implemented in Canada, spanning a full city block. Two new 50,000-square-foot concourses below the existing station flank the central concourse, relieving the physical constraints of the heritage structure. Designed with heritage architect EVOQ, restoration of the Head House and VIA Concourse was completed through a phased approach that maintained transit operations throughout construction.
Outcome
The revitalized station enhances capacity, connectivity, and the passenger experience while preserving an important piece of Canada’s transportation heritage. Together, the expansion and restoration position Union Station to accommodate projected future growth and continue serving as the country’s busiest transportation hub for decades to come.

Spanning nearly one million square feet, the revitalization expands Union Station’s capacity to support growth from 60 million to 130 million passengers annually by 2036.
Beneath an active National Historic Site, two 50,000-square-foot concourses were constructed four metres below grade while transit and rail operations continued uninterrupted.
