I don't know if you've used the US version of eBay, and searched for camera gear there, but it's not uncommon for more than half the results of any given search on specific equipment to be from Japanese sellers. And their sticker prices tend to be lower than what the US sellers are charging: they have to be, if they weren't, they'd be locking themselves out of that market.
For example, I just searched eBay for "Olympus Pen F" and sorted by price. Out of the first 20 results, 14 are Japanese, 6 are US sellers.
For Canada to be a bigger import market than US for Japanese cameras, due to the population difference, the Canadian interest in these products would have to be 8 or 9 times the US interest per capita... nothing about that adds up to me as realistic. Frankly, I find people from Canada and the US to be very similar in their interests.
