[](https://www.designboom.com/tag/foster-and-partners/) [Foster + Partners](https://www.designboom.com/tag/foster-and-partners/) has officially begun construction on ‘the one’, a mixed-use skyscraper in toronto that is set to become [Canada’s](https://www.designboom.com/tag/architecture-in-canada-news/) tallest building. the development, which will be the country’s second tallest man-made structure after the CN tower, will climb to a total height of 306 meters, or 1,004 feet. Situated at the border of downtown and the city’s Yorkville neighborhood, the 85-storey structure seeks to stand as a new landmark on the city’s constantly evolving skyline. _‘The one is the final piece of the jigsaw in the tower cluster at the Yonge and Bloor node — one of the most prominent intersections in the city,’_ says Giles Robinson, senior partner at Foster + Partners. Backed by [Mizrahi Developments](http://mizrahidevelopments.ca/), [‘The One’](http://onebloorwest.com/) differentiates between the commercial units at its lower levels and the residential apartments above. _‘the structural frame is clearly expressed on the façade creating a distinctive series of vertical, horizontal and diagonal framing elements that are clad in a champagne bronze color,’_ explains [foster + partners](https://www.fosterandpartners.com/). _‘the building is further articulated with the introduction of horizontal bands at regular intervals where mechanical floors are located.’_
