James Cooper House 1881
Designed in the Second Empire style, this landmark building features a mansard roof with dormers and rich detailing in stone and wood. From its completion until 1894, it was the private residence of James Cooper, a partner in the prominent footwear manufacturing firm, Cooper and Smith. In 1910, the home was acquired by the Toronto Council of the Knights of Columbus, a Roman Catholic fraternal and mutual aid organization that remained here for the next 95 years. The house was then moved forward and incorporated by Tridel Group into a residential tower, completed in 2010.
