May not ship to Canada..all over ebay now

I have had good experience selling to Canadians, but a couple deals recently the topic was brought up about the poor exchange rate, and cost of shipping, so could I lower my price. I sympathized, but my price was no higher then if someone walked up to my door. I would like to help, but both those problems are not within my control.
What can a guy do? The biggest hassle I have seen is if the item is sheet metal, Then the problem is big.
