Ottawa Wizards were a Canadian soccer club which operated in the Canadian Professional Soccer League (CPSL), from 2001 to 2003. The team's home stadium was the OZ Optics Stadium. Though the team had a relatively short tenure with the CPSL, the club dominated the league by winning three consecutive regular season championships, two Open Canada Cups, and the CPSL Championship. Despite the club's success the franchise was revoked by the league in 2003 after several legal disputes with the CPSL administration.

The Canadian Soccer League is a semi-professional league for Canadian soccer clubs primarily located in the province of Ontario, and claims the history of the Canadian National Soccer League (CNSL). It is a non-FIFA league previously sanctioned by the Canadian Soccer Association (CSA), but now affiliated with the Soccer Federation of Canada (SFC). As of 2023, it consists of seven teams, all located in Ontario. The season usually runs from May to October, with most games played on the weekend followed by a playoff format to determine the overall champion.
