Re: US TCH in Canada
For that length of stay, yes an Ontario license is necessary. I believe if the driver has 2 yrs of driving experience from previous jurisdiction, no testing is required, just a simple application.
As for the car, I think the main requirement to meet Canadian standards is lighting, most commonly that Daytime Running Lights cannot be turned off. However, I'm not sure you actually need to or would really want to transfer the registration. Transferring a US car to Canadian registration means paying import duties and sales taxes. If the car is registered in your name, as long as the vehicle registration is kept current and your son is properly insured to drive the car in Canada, I'm not sure there is anything illegal about him "borrowing your car" while at school. It might be different if the car was in his own name. Just my opinion though...
