Work on Fosters' Toronto tower starts

Work on Canada’s tallest building designed by Foster & Partners has begun.

Called the One, the scheme in Toronto will be just over 306m tall – just over one metre higher than Eric Parry’s planned One Undershaft in the City of London and set to be the Square Mile’s tallest – and run across 85 storeys. It will includes a 175-room hotel and a 60 floors of condo apartments topped by multilevel penthouses.

Fosters is working with local practice Core Architects.

The CAD$1bn (£605m) project is being developed by local firm Mizrahi.

Although set to be the tallest building in Canada, the scheme is still lower than the CN tower elsewhere in the city. The communications and observation tower is 553m tall.
