Things have changed a bit though.  Back in 1980 Pierre Trudeau didn't win a so much as a single one of the 63 seats in SK, AB and BC, but won 74 of the 75 seats in Quebec.  That was just over half of the seats the Liberals won for the country as a whole.

Today though there are 88 seats in SK, AB and BC combined vs. only 78 seats in Quebec.  The Atlantic Provinces, meanwhile, still have the same 32 seats that they had in 1980.

Ontario is still the big battleground, with 121 seats in the house.  The real question here is who is going to take the 60 or so suburban seats in Ontario.  Downtown Toronto will vote Liberal or NDP and rural Ontario will vote Conservatives, but there are a lot of seats up for grabs in between those two.
