Shipping to Canada. Question for you folks up north

So I see often the debate on shipping to Canada. I personally don't just because I pay the shipping on items I sell. The USPS does do flat rate postage, which is generally around $30.00 more. It's not that I don't want to sell parts to you, just the shipping price. The paperwork is a snap and takes seconds to fill out. Maybe this post can help us out down here about your thoughts on the high (to me) shipping costs.
What are your opinions about this?
