Have you tried www.theknot.com? I used that a lot since we were planning from a different state than where we got married. They also have message boards - I think Canadians use the Michigan one for a local board.
There is another one that people have mentioned, but I completely forget the name. I'll have to think about it.
Wedding Bells has a Canadian version website. If you are looking for vendors, you can use Bridal Fair . Just go to the "local stores" page and choose regions you need.
The Knot and Wedding Channel are tailored to brides in US. But you will get some good ideas from the message board.
