Construction at The One (1 Bloor St W), located on the south-west corner of Yonge and Bloor, has now surpassed the 43rd storey and 150 metre mark — making the current height of structure officially reach skyscraper status.

The milestone comes after news that the project has been placed under receivership. Despite the numerous construction hurdles and financial uncertainties faced by the project, Mizrahi Developments is remaining in place as the Developer and General Contractor that will oversee the continued construction on the tower.

Designed by UK-based Foster+Partners, the 91-storey / 328 metre supertall skyscraper is currently the tallest approved building in Toronto and will contain retail, an Andaz Hotel, and high-end residential condominiums.

Construction on the project officially began in 2017, with the tower employing a number of unconventional design and complex construction techniques. This included an equivalent 8-storey excavation below grade, a soaring ‘column-free’ flagship retail space, and a unique structural exoskeleton design. In the years since, the development has become one of the most watched construction sites in the entire city.

The installation of a temporary Rail Climbing System (RCS), has allowed construction crews to finish the tower’s exterior within the confines of a protected envelope. Cladding installation has now reached the towers 11th storey at the time of writing.

Further up at the top of the structure, construction crews are now forming a new level on the tower approximately once every week.

While it remains to be seen whether The One will meet its targeted completion date of Spring 2025, Urbanize Toronto will closely follow continued progress on the development.
