A Kazakhstan company unveiled plans today for an 80-storey tower that will change the landscape of the Yonge and Bloor streets intersection.

The sleek building will be Toronto's tallest residential-commercial building and the tallest condominium structure in Canada.

The company's president, Michael Gold, said the tower will be "so bold, so striking" that it will become an "instant icon."

The tower will go up at the intersection's southeast corner, which is currently occupied by a Harvey's restaurant and a billboard.

Demolition of the old structure is expected to being this year.

The new tower, to be named 1 Bloor, is expected to open in 2011.
