1958 CFL season

The 1958 CFL season was the inaugural season of the Canadian Football League, although the season structure was essentially unchanged from the one established three years earlier when the league's founding unions (the Interprovincial Rugby Football Union and the Western Interprovincial Football Union) had effectively barred amateur teams from competing for the Grey Cup.

The Hamilton Tiger-Cats and Winnipeg Blue Bombers met again for Canadian football supremacy. The Blue Bombers turned the tables on the Tiger-Cats this time, winning their first Grey Cup since 1941.
