Thanks and I did call one of the dealer and he told me I can buy the tow hitch but they cannot guarantee that it fits.The Canadian accessory tow hitch from Toyota will absolutely fit the US spec RAV4. There is no physical difference in the body or frame structure of any RAV4's built for the N. American market. The bumpers are also identical.
I don't know if the accessory tow hitch is available yet at Canadian dealers. i didn't ask, as I have no interest in spending over $1200 for a wired hitch that will only carry a bike rack. All you need to do is phone any Canadian Toyota dealer's parts dep't and ask for a price on the hitch uninstalled, in a box.
Without installation, it cost $725 + tax but I need to have someone to go buy it and mail to US as they cannot accept order from US.
