Championships
The Vanier Cup was played between the champions of the Mitchell Bowl and the Uteck Bowl, the national semi-final games. In 2003, the Uteck Bowl replaced the long-standing Churchill Bowl, which had been competed for since 1989 as a national semi-final game. Along with the Mitchell Bowl, the semi-final games now worked on a fully rotating basis, with the winners of the Canada West conference Hardy Trophy visiting the winners of the Atlantic conference Loney Bowl championship for the Uteck Bowl. The Ontario conference's Yates Cup championship team hosted the Dunsmore Cup Quebec champion for the Uteck Bowl.
