Welcome to The Permanent. Formerly known as the Canada Permanent Building, 320 Bay was built in 1931 on the most important corner of Toronto’s financial core at Bay and Adelaide. At 18-storeys 320 Bay was the tallest building at the time and its history has intrinsically been linked to the history of the city, creating a real Toronto legacy. A true legacy doesn’t happen overnight; like your business, it is grown and developed over time. The Permanent is undergoing a full retrofit and offers over 300,000 square feet of office space available for lease. The building features stunning art deco exteriors, golden coffered entrances, and a main-floor grand banking hall that stuns with brass detailing and elevators, intricate ceiling treatments and elegant arches. In addition to its unique yet ideal features, The Permanent connects you directly into Toronto’s underground PATH network (which leads to First Canadian Place). Located in the heart of the Downtown Core, the building is within a 5-minute walk to all downtown transit including Union Station, TTC subway, streetcars, buses, and Go trains. With an abundance of amenities at The Permanent’s doorstep, your employees will have unending possibilities for entertainment, lifestyle, and business necessities at their convenience. Build Your Legacy, join the movement and be part of the growth that will define the Financial Core for generations to come.
