That might not be a particularly good idea. Nikon Canada will not recognize the warranty on that lens, so if it does need any warranty work (and post-warranty work), you will have to ship it to Nikon USA. If you want a Canadian supplier; check with Aden Camera in Toronto. I've bought most of my lenses there and they seem to have the best prices in Canada.
