What’s the history of 100 Adelaide St W?

PATH spans 30 km of walkways, making it the world’s largest underground shopping complex (Parking.com PATH). For workers and visitors at 100 Adelaide St W, this means access to food courts, retail services, and transit connections without stepping outdoors—particularly valuable during Toronto’s harsh winters.

The catch: PATH hours vary by building. Not all connecting passages operate on the same schedule, so visitors should check individual building access times before planning a winter commute through the network.

What is the EY Tower?

The EY Tower is a 40-storey commercial skyscraper located at 100 Adelaide Street West, forming the anchor of the Richmond-Adelaide Centre—a 2.5 million square foot office complex owned and managed by Oxford Properties (Oxford Properties EY Tower). The tower takes its name from Ernst & Young, the global professional services firm that occupies significant office space within the building. The complex encompasses multiple structures connected through shared amenities including the underground parking facility, PATH concourse, and retail services.

Key features

• 40 storeys of Class A office space
• LEED Platinum sustainable building certification
• Five levels of underground parking (288 spaces total)
• Direct PATH network connection at concourse level

Tenants and complex

The Richmond-Adelaide Centre includes multiple buildings, with the EY Tower representing the most recently completed component. Oxford Properties manages the entire complex, which features shared underground parking and PATH access across the development. The complex size of 2.5 million square feet makes it one of the largest contiguous office developments in the Toronto financial district (Oxford Properties EY Tower).

The pattern: Major professional services firms anchor EY Tower, while smaller tenants benefit from the shared infrastructure of a 2.5 million sq ft complex at a location that would be impossible to replicate as a standalone building.
