The 1907 Dominion Championship was a Canadian football game that was played on November 30, 1907 at McGill University in Montreal, Quebec that determined the Senior Rugby Football champion of Canada for the 1907 season.[1][2] This was the first championship game to feature the newly created Interprovincial Rugby Football Union (IRFU) champion, which was the Montreal Football Club. Montreal defeated the Ontario Rugby Football Union (ORFU) champion Peterborough Club in a 71–10 blowout victory to win their second Canadian Championship.[1][3][4] This was the eighth appearance in the title game for Montreal and the first and only appearance for Peterborough.[2][1] Notably, referee Russell Britton admitted after the game that there was a scoring error when a touch-in-goal (one point) was given to Montreal when it should have counted as a try (five points).[3] While the score should have been 75–10, it was officially recorded as 71–10.[1][3][5] This was the highest scoring Dominion championship/Grey Cup in Canadian football history.[1][2]
