Field conditions were poor, as a steady downpour left sheets of water over the artificial turf at Empire Stadium.
Calgary opened the scoring with Herm Harrison making an incredible one-handed grab of a Jerry Keeling pass in the end zone for a touchdown.
Toronto countered with a big play, a 55-yard pass reception by fan favourite tight end Mel Profit, but would come away from this drive deep into Stampeder territory with only a field goal from Ivan McMillan.
Late in the fourth quarter Dick Thornton, a great two-way player who had already made a fantastic reception, intercepted a Calgary pass and returned it to the Stampeder 11-yard line.
As McQuay cut left, he promptly slipped on the soggy turf and fumbled the ball, which was recovered by Stampeder Reggie Holmes.
Dick Suderman, the first recipient of the newly created Most Valuable Canadian award for the game, died the following year and the trophy was renamed in his honour.
