It has been a while since I have done this but the answer is definately Yes.
Keep your receiots and when you come back into the states stop at customs
and present your receipts to them. I'm not sure that they refund both GST
and PST but they will refund one of the two (or both can't remember). Like
Ian said this applies to good not Alcohol, Food, or services.

Again some of my points could be a bit off because it has been a long time
since I have been to Canada. Which is crazy considering my home town has the
International Blue Water Bridge and Sarnia is just across the bridge.
