One Bloor, previously One Bloor East and Number One Bloor, is a mixed-use skyscraper under construction at the intersection of Bloor Street and Yonge Street in downtown Toronto, Ontario, Canada. The project was initially launched by developer Bazis International Inc. in 2007, before being cancelled and re-developed under developer Great Gulf Homes. The two-storey buildings located on the site were demolished in December 2008. The 76-storey tower topped out in late 2015.
