The Ontario Club was a private club in Toronto, Ontario that existed from 1909 to 2010. The club was founded as a gentlemen's club, but in 1978 became mixed-sex. The Ontario was organised as a home for members of the Liberal Party of Canada, and as such, was the counterpart to the Albany Club, which was for members of the Conservative Party of Canada. From 1912 to 1969, the Ontario Club had a clubhouse on Wellington Street. After it sold the property to the Canadian Imperial Bank of Commerce, from 1972 to 2007, it occupied the top floor of Commerce Court South. In 2011, the Ontario Club merged into the National Club.
