Game isn't till sunday because of a Coldplay concert at Rogers. Seriously don't get the mutual antagonism between Vancouver and Toronto fans though.
It's not really Toronto vs Vancouver so much as all of Canada outside of Vancouver vs Vancouver, and all of Canada outside of the GTA vs Toronto. If it ever came down to Vancouver vs Toronto, the rest of Canada would implode, unsure of who to root for (Not really, I think they probably hate Toronto more)
A large part of it is seperate from the world of hockey; there's a lot of hatred for the two cities just in general.
All of Canada sees Toronto as having an inflated sense of ego, trying to be New York and pretending we're superior to the rest of the country.
And they see Vancouver in exactly the same way, but replace "New York" with "LA"
When it comes to hockey in particular, you've got that, plus the fact that Vancouver also has rather unsporting fans, and an even more inflated sense of ego (Ask them why the rest of Canada hates Vancouver's team and they'll tell you it's jealousy, because they are the "Prom King"), and it's also a team captained by a Swede that plays a much more European style of hockey complete with many a dive.
Meanwhile they hate Toronto because on top of the already prevalent hatred for the city, Toronto is given preferential treatment by the media, literally declares itself "Canada's team" (There's that over inflated sense of ego again), hasn't won in 45 years and still acts like it's a champion. It's also got an overabundance of Americans, and an American GM, which makes it's "Canada's team" boast seem all the more unfitting.
