Looks like flatrate is maybe $20? I can help too if Foxhack can't do it, but he's a pro at shipping, I'm sure.
I think I have a lot more free time to go to the post office than you do. Since, you know. I'm unemployed. :p
A Flat Rate Envelope costs $23.95 to ship to Canada. The good news is, I have a few leftover padded flat rate envelopes, and I can fit several games in there, up to four pounds worth of stuff. If you'd like me to help you out, lemme know via PM and I'll give you my shipping info.
