Let's see, my top 3:
Michel and Pierre (Wide array of skills, keeping their heads cool)
Mickey and Pete (They're more of a wild card. No way of knowing where they end up)
Cormac and Nicole (Hey, both the previous Canadian winners and the most recent US winners were a parent-child team)
I don't have a lot of faith in either gay couple or in the brother-sister team, but I could also see the hockey players, the co-workers or Alain and Audrey claim the prize.
