Yeah as a fellow Canadian I am all too familiar with the ordeals of ordering from the States. But since there is little to no selection in Canada, our hands are basically tied.
I find most sites ship boards for about $50-$80.
DogFunk is quick for shipping to Canada, but suprisingly Backcountry or Department of Goods (which are the exact same store as Dogfunk) both will ship the same product for cheaper... figure that one out.
Sierra Snowboard actually will ship to Canada for free if you buy $500 or more of product. However, they won't be carrying 2011 Never Summer boards (I already checked... bummer, I know)
It's a long hard road ahead, when buying gear from the States, but in the end it pays off with the money saved. I would love to support local shops more, but it's hard to afford spending DOUBLE when you are barely scraping by on a ski-bum's income.
