The National Hockey League's Canadian Division was formed after expansion in 1926.
Despite its name, the division contained at least one team based in the United States throughout its existence.
Under the cross-over playoff format then in use, Canadian Division teams contested just one intra-divisional Finals, compared to three such series played by American Division teams.
Notably however, Canadian teams won all twelve division titles and were the only teams from the division to reach the Finals during this time, also, each of the four Canadian teams then in existence won the Cup at least once.
The league collapsed into one single table, reverting to the format of the 1925–26 season, after the Montreal Maroons suspended operations in 1938.
