Even after the end of U.S. expansion, American investors continued to be involved with the CFL for many years at the ownership level, notably in Calgary and Ottawa. By the end of the first decade of the 21st century, all extant franchises except Montreal had come under Canadian ownership, leaving the Alouettes' Wetenhall as the league's only American owner. Wetenhall sold his franchise back to the league prior to the start of the 2019 season, thus putting the CFL under exclusively Canadian-based ownership for the first time in decades.
