The National Soccer League was a soccer league in Canada that existed from 1926 to 1997. Teams were primarily based in the provinces of Ontario and Quebec. The league was renamed to Canadian National Soccer League in 1993 following the folding of the Canadian Soccer League, and the accepting of the Winnipeg Fury, making the league more national. In the 1960s, the Canadian National Soccer League was one of four major leagues in Canadian soccer alongside the Pacific Coast League, the Eastern Canada Professional Soccer League and the Western Canada Soccer League. It was replaced by the Canadian Professional Soccer League in 1998, after an agreement between the CNSL and the Ontario Soccer Association.

NSL/CNSL clubs

Clubs are listed by name and year that a club by that name participated. Whether clubs by the same name were indeed the same club or not has not been made clear by the source used for compiling this list. Note as well that the same source does not include information for the Eastern Division of the league from the 1930s through to the 1950s, nor any information at all for the following seasons: 1968, 1969, from 1983 through 1992, and 1994. Moreover, the source provides only an incomplete list of teams for 1947 through 1949, and, for a few other seasons, not all team names in full.
