Cheapest flight from Vancouver to Niagara Falls?

[TLPL]

Hello everyone,
I am planning a Disney Cruise for next year which depart from L.A. and end in Vancouver, BC. Anyone has any advice on flight from Vancouver area back home to Niagara Falls, ON? Would it be Toronto, Hamilton or Buffalo that cost the least?
What about flying out of Seattle? Would that be an option?
I have no idea what to do, and I need your help.
Thanks in advance.

There will be lots of flights from Vancouver to Pearson. The problem will be cost. You would be better off price wise getting to Seattle and flying to Buffalo-Niagara. One of the appealing aspects of the 2012 Alaska cruises is that they are out of Seattle which is a lot cheaper to get to than Vancouver. We live in Toronto and now that the kids are older fly out of Buffalo-Niagara. The price difference can result in savings of 50% quite easily compared to Pearson.

We're doing the Vancouver-LA this September.
Booked my air "Multi" from Toronto on AirCanada October 2011.

Best rate I could find for a direct flight. If you don't mind stops I'd try Buffalo.

That sounds cool. But how do you get from Vancouver to Seattle? We probably going to stay a day or two in Vancouver sightsee. Can we renting a van one way since Vancouver and Seattle are in different country? Will that cost lot?
