Canadian consignors:
I've gone to Patricia at
http://www.constylement.com, and she's terrific to work with (as a consignor). She's absolutely lovely and knowledgeable (and a member here on TPF)! She doesn't have a storefront, but does most of her business online.
Just stopped by
http://www.hauteclassics.com, and Stella and Gina seem very nice as well. They're half a block from where I live, so I'm contemplating doing some work with them to try them out. Both are very friendly and seem to know their stuff. Their physical store is at Yonge & Belmont. They had the most gorgeous lavender Prada croc clutch ever. Too bad I got there too late - it was already sold.
Labels or Love is also another local Toronto consignment shop. I don't know if they sell online, but they carry very high end items. They're up at Lawrence and Avenue, for you Torontonians. They've carried Chanel and Hermes.
Another high end consignment shop is Second Time Around in Yorkville. Karen and Danny are nice to work with, but the last time I asked, they didn't have any interest on running a business online. Lots of Dior and Chanel and Vuitton.
Chanel Touch isn't local to Toronto - I think it's based just outside of TO, but Cyndee is a member here, and she has the loveliest Chanel and Vuitton collections for sale! She sells on

Hope this helps out my fellow Torontonians (and Canadians)!
