American competitions At various times, Canadian clubs have competed in the top-tier of American soccer, either in place of or alongside a Canadian top-tier league. Currently, three Canadian clubs compete in Major League Soccer.
United Soccer Association (1967) National Professional Soccer League (1967) • Oakland also won the NPSL Commissioner's Cup nine days after winning the NPSL Finals.
North American Soccer League (1968–1984) • – The 1969 season featured no playoffs; the league title was awarded to the team with the most points in the season. • – The
New York Cosmos dropped "New York" from name for the 1977 and 1978 seasons, then returned to the full name in 1979 season.
Major League Soccer (1996–present) U.S. Open Cup (1914–present) Historical era Modern era • – Championship awarded to Paterson when Scullin were unable to field a team for the replay, due to injuries and players under baseball contracts beginning the baseball season • – Before the
Spring 1931 season,
Fall River F.C. moved to New York City and merged with
New York Soccer Club to become the
New York Yankees. However, they began the 1931 tournament under the name Fall River, and as such were required to play as Fall River for the remainder of it, and won the Cup. Before the
Fall 1931 season, the Yankees moved again, this time back north to
New Bedford, Massachusetts. They merged with
Fall River F.C. to become the
New Bedford Whalers, and again won the Cup in 1932. The
USSF officially credits "Fall River F.C." with four championships in total, and "New Bedford Whalers" with one. • –
St. Louis Soccer League team names were determined by the club's respective corporate sponsor. The team known as
Hellrungs from 1929 to 1931 was also known as "Stix, Baer and Fuller F.C." from 1931 to 1934, "St. Louis Central Breweries F.C." from 1934 to 1935, and "St. Louis Shamrocks" from 1935 to 1938. As the change was only cosmetic and no relocations or mergers with clubs resulting in new rosters were made, the club's title history continues with the name changes. • – Aggregate drawn 2–2, Championship shared when details for a third game could not be agreed upon. • –
Brooklyn Dodgers S.C. returned to their original name of "Brooklyn Italians" before the 1990s (the club states the change was in 1974, though later U.S. Open Cup tournaments have them registered under the Dodgers name).

Overall totals Defunct franchises: . • – If the full histories of the domestic cups were included, the table would be some 150 teams long and include dozens of defunct, historical, and strictly amateur (North American Division 4 or 5) squads. As North American Soccer League teams did not compete for the domestic cups, and for the sake of practicality, only the modern eras of the two domestic cup trophies (since 1995 for the U.S. Open Cup and since the inception of the Canadian Championship in 2008) are included in this particular chart. For full domestic cup histories and totals, see below. • – The current incarnation of the franchise is a namesake
