The McMaster Marauders remained in top spot in the last Canadian Interuniversity Sport football rankings of the 2012 regular season.

The reigning Vanier Cup champions were ranked No. 1 in each of the 10 weekly polls this fall. The 8-0 Marauders were the only team in the country to keep an unblemished record in conference play.

McMaster received all 30 first-place votes to remain ahead of the No. 2 Laval Rouge et Or (8-1).

The rest of the top five remained the same. The Calgary Dinos (7-1) were No. 3, followed by the Montreal Carabins (8-1) and Guelph Gryphons (7-1).

On Saturday, playoffs begin. The Marauders play the Western Mustangs. The winner goes to the Yates Cup.

The two teams last played on September 29. The Marauders won 33-27 on Western's homecoming weekend. Western is ranked No. 6 in Canada.
