Canadian Football News in 1906 included the following changes.
Specifications were first made for the size of football, where the ball had to be 11 inches long, 23 inches in circumference and 13 3/4 ounces in weight.
Goals from the Field and Free Kicks were increased to four points in the ORFU. Games were four 15-minute quarters in length. CIRFU lowered Goals from the Field to four points and Free Kicks to three points. Calgary City Rugby Football Club was formed March 14 at Calgary City Hall.
The Manitoba Rugby Football Union saw the four teams play an unbalanced schedule. Each team could earn a maximum of 30 points on the season. The value for a win was determined by the formula (30 divided by number of games scheduled). The Winnipeg Football Club was awarded 5 points per win; the Winnipeg Rowing Club and the St.John's Rugby Football Club were awarded 6 points per win and the Brandon Football Club was awarded 7.5 points per win.
The Winnipeg Football Club had difficulty getting a full team to show up to games and they folded midway through the season. The Winnipeg Football Club defaulted one game to each of the other teams. The final game of the season between the Rowing Club and the St.John's was not played as the Winnipeg Rowing Club had already been crowned as champions.
