The 2006 Canadian Soccer League season was the 9th season for the Canadian Soccer League. The season began on May 19, 2006, and concluded on October 15, 2006, with Italia Shooters defeating Serbian White Eagles, 1–0, at Esther Shiner Stadium to win their first CSL Championship. In the regular season Serbia clinched the International Division, and Oakville Blue Devils secured their first National Division title. The league was re-branded as the Canadian Soccer League, and renamed their two existing conferences into the International and National division. The changes brought about an increase in sponsorship, media coverage, and a 50% increase in attendance. The CSL also received greater autonomy from the Ontario Soccer Association. The league struck an agreement with the Toronto Community News which provided coverage for the league and its member clubs through their nine community newspapers.

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.
