Some car rental companies allow their vehicles to be driven in other countries, most US companies allow you to drive your vehicle into Canada with prior authorization.
Does this authorization mean that the rental company will provide liability coverage that's mandated by Canadian/US law?
(Assumptions, the renter declines the Supplemental Liability policy offered by rental car companies, the renter doesn't have automobile insurance in their home country, the renter doesn't have a non-owner policy in their name)
My question is specific to rentals between USA and Canada, I'd also be curious to know about how this is handled in other countries where this is sufficiently common like within the EU.
This is similar to another question that I've asked here.
