General Info

About the Project

Project Description

CIBC’s new global headquarters located in the heart of Toronto’s ‘Union Station Heritage Conservation District’ will feature two office towers joined by a “Sky Park” rail corridor overbuild. The dramatic 2-tower development (49 and 54 stories), features a shared retail podium and a fully integrated Metrolinx bus terminal. The complex brings several public amenities to the precinct (including a soaring lobby, elevated park, and renovated teamway connecting 81 Bay and 141 Bay) and links together transit destinations with pedestrian bridges and underground links (Toronto’s financial core, Air Canada Centre, Union Station, Bus Terminal, underground parking and the PATH).

Eric Cornish Executive Vice President
Located in the heart of Toronto, the tower at 81 Bay Street is the first phase of a grand-scale, mixed-use development that is dedicated to enhancing the wellbeing of not just its own occupants, but people in the surrounding area.
