Ottawa SuperEX was an eleven-day annual exhibition that took place every August at Lansdowne Park in Ottawa, Ontario. The exhibition provided exhibits, entertainment and amusements indoors in the buildings on site and outdoors on the grounds. The Central Canada Exhibition Association operated a fair annually from 1888 until 2010, except during World War II. The fair was on hiatus due to plans to redevelop Lansdowne Park and the Association continued to work towards finding opportunities to bring back SuperEX. It was announced in December 2015 that the Ottawa SuperEX board had disbanded a year earlier and the Ex would not be returning.

The Western Fair is a fair held annually in London, Ontario, Canada in early September.
