I've sent small items from here in Anchorage to my best friend, who moved to London, ON. She had to pay taxes on some of those items, even if they were marked as gifts.

My hunch is that you will end up paying some kind of fees, beyond just shipping, that would end up making the price of your items meet (or even exceed) the Canadian retail prices.

I live in the Fraser Valley and am, in the next few months, after extensive research using this forum and other venues, going to be buying appliances for a new build. Now that the dollar is almost at par(I got $98 US for $100 CDN at the bank), shopping across the line sure is attractive, since our appliance prices have not dropped to keep in line with US prices...I'm hoping that will change shortly(that may be wistful thinking).
Last August my husband and I went to a Mariners game and stopped at a Seattle appliance store by the field(Direct Buying Service). At the time I was fired up to buy a Blue Star. The manager told me that one in four of them needed tweaking right out of the box, and that the problem with customers that had bought things from his store to bring across the line was that it was difficult for the servicemen to receive financial compensation for work done from Blue Star, as it was work done in another country.
Now, I'm not sure if that would be the case with Wolf or Asko(a dishwasher I'm quite interested in as well), but I would be worried about hassles with warranty service work that might need to be done.
That and as Braytonak pointed out, you should check with customs and see how much duty you will end up having to pay on everything and see if the price differential is worth the hassle.
