The battles for two of the most tradition-steeped trophies in Canadian sports are heating up. On Saturday, the matchup for the 110th Grey Cup game will be decided while the chase for the 58th Vanier Cup gets cut to four teams.

Here's what to know for a big day of Canadian football playoffs:

CFL division finals: Are we headed for a Grey Cup rematch?

According to the betting markets, probably. Reigning league champion Toronto is favoured by 11 points over Montreal in the East final (3 p.m. ET), while Winnipeg is a five-point favourite to defeat B.C. in the West final (6:30 p.m. ET) and reach its fourth consecutive championship game.

Toronto looks especially tough to beat right now. Since upsetting Winnipeg in last year's Grey Cup, the Argonauts have morphed into a juggernaut, matching the CFL single-season wins record by going 16-2 as quarterback Chad Kelly blossomed into a star.

After coming off the bench in last year's Grey Cup, the 29-year-old nephew of Buffalo Bills great Jim Kelly capitalized (literally) on his first shot at a full-time starting job in the pros. He threw 25 touchdown passes and rushed for eight more to earn the East nomination for the CFL's Most Outstanding Player award and become the league's highest-paid player. 

The Argos, who enjoyed a first-round bye last week, won all three of their regular-season matchups with Montreal. But the Alouettes (11-7 this season) can harbour some hope of slowing down Toronto after surrendering the second-fewest points in the league and then keeping Hamilton out of the endzone during last week's 27-12 playoff win.
