Oxford Properties Group (Oxford), the global real estate arm of OMERS, is planning a $3.5 billion development called Union Park in downtown Toronto that would be the city’s biggest mixed-use project to date.

The project features 3.3 million square feet (sq. ft.) of offices, 800 rental apartments, 200,000 sq. ft. of retail. In addition, Oxford plans to build a two-acre urban park over the Union Station rail corridor, spanning between Blue Jays Way and the John Street Bridge. Designed by OJB Architects, it “aims to deliver much-needed public green space in the heart of Toronto’s downtown core next to some of the city’s most popular tourist destinations.”

“This is a transformational project in one of the most exciting development nodes in Toronto,” commented Eric Plesman, executive vice-president of North America, Oxford Properties in the press release. “Befitting its status as one of the largest redevelopment projects in North America, and the largest in Toronto’s history, Union Park will feature world-class design from a globally-renowned architecture team. Our goal at Oxford is to connect people to exceptional places, so we are creating an ambitious project that adds to Toronto’s ongoing evolution as a world-class city to live and work in.”

Union Park has been designed by Pelli Clarke Pelli Architects, best known in Canada for  The Stack in Vancouver.
