I can certainly relate to being treated differently, as, here in Ecuador, we don't even have a Canon store or any kind of loyalty program, plus, Optical Elements are taxed with 20% and then 12% VAT, so you can imagine, prices sky rocket for this type of equipment.
What we do is:
- Buy from Amazon (or any other online store) and then either
a. Have someone bring over the item (most of us are certain to find a friend that is making the trip) or
b. Import them individually through customs, which, as luck will have it, if the package is under $400 or 4Kgms., is not taxed.
I don't know if any of this procedures would be considered illegal in Canada, here it certainly isn't, our customs are always involved in the process and we don't have any problems. The only minor caveat would be the warranty, but, since here no one can honor any type of Canon warranty, we don't make any issue of it, perhaps for you its a bit different. Could you register for warranty (in Canada) a camera bought in the US?
If that's the case you could have the Loyalty Program applied in the US and then brought to Canada?
Just thinking of the options as we always have to find ways here in Ecuador (legal always, of course, no black-market stuff)
