My son’s car broke down, and we’re currently using his grandfather’s car until he finds a new one. I have a question about insurance: should we keep the insurance on my son’s old car until he gets a new one, or does he need insurance now that he’s driving a car that’s already covered by his grandfather’s insurance? This is in Ontario, Canada.
Son’s car died, using Grandfathers car till he finds a new one. Insurance Question

In Ontario, Canada, it’s important to understand that every vehicle must have its own insurance policy, regardless of who owns it. If your son is using his grandfather’s car, it should be covered under his grandfather’s insurance policy. However, your son will still need to be listed as an occasional driver on that policy to ensure he is fully covered while driving the vehicle.
As for the insurance on your son’s car that has died, he should keep that policy active if it’s not yet canceled or transferred to a new vehicle. This is especially important if there are any remaining issues with the old car that could lead to liability, or if you want to avoid any gaps in coverage when he eventually gets a new car.
Before making changes, it’s a good idea to contact the respective insurance providers for specific advice, as they can provide you with the best guidance for your unique situation.
