The Interprovincial Rugby Football Union (also referred to as the Big Four) grew out of an amalgamation between the Hamilton Tigers and the Toronto Argonauts of the ORFU and the Ottawa Rough Riders and the Montreal Foot Ball Club of the QRFU on September 13. As a result of Ottawa and Montreal leaving, the QRFU withdrew from senior competition. The Ottawa entry was the result of the amalgamation of the Ottawa St. Pats and Rough Riders.

Montreal won the Big Four's first game, 17–8 over Toronto and later became the league's first championship team.

Calgary City Rugby Foot-ball Club played its first game on October 31 and defeated the Strathcona Rugby Foot-ball Club 15–0 at Calgary.

Teams had to gain 10 yards in three downs; a Try was five points; a Goal from a Try was one point; a Goal from the Field was four points; a Free Kick was three points and a Penalty Kick was worth two points.
