In the late 19th century, Canadian football began to take shape, with the formation of the Interprovincial Football Association (IFA) in 1907. The IFA, which consisted of teams from Ontario and Quebec, established the first set of rules for Canadian football, which were based on the British game of rugby.

    In the 1990s, the CFL faced significant challenges, including declining attendance and financial difficulties. However, the league has since rebounded, with the introduction of new teams, such as the Ottawa Rough Riders (now defunct) and the Toronto Argonauts' move to their current stadium, BMO Field.

    The 1970s and 1980s saw the emergence of legendary Canadian football players, such as Wally Buono, a two-time Grey Cup champion and the all-time leading rusher in CFL history. Other notable players from this era include quarterback Don Matthews, who won four Grey Cups, and defensive back, Norm Fieldgate, who played for 14 seasons and won three Grey Cups.
