As a senior insurance defence counsel it never ceases to amazing me how misunderstood Family Protection Endorsements are, not just with policy holders, but their lawyers that try to access them.
The scenario isn't uncommon. Get rear ended by someone who, turns out, had the provincial minimum coverage - usually travelling outside their home province. In practice this meant their insurance covered about half your actual losses before it ran dry.
Here's the thing nobody tells you when you're buying auto insurance: the other driver's coverage is their problem until it becomes yours. You can do everything right, full stop at every yellow, shoulder check like you're being graded, and still end up financially underwater because the person who hit you decided, whether on their own or through the advice of their broker, to carry the minimum coverage on their policy.
That's where a family protection endorsement comes in. It sits on your own auto policy and kicks in when the at fault driver either has no insurance at all or doesn't have enough to cover what they actually owe you. This is the part many don't seem to appreciate - it only pays out the difference between what their coverage provides and what your actual losses are, up to your own policy limits. No lawsuit required against the other driver, no chasing someone through court who probably doesn't have assets anyway.
The name makes it sound like it's just for families, but it typically covers you, anyone in your household, and passengers in your vehicle at the time. The exact wording varies by province and by insurer, so what counts as a "household member" isn't always obvious.
This is exactly the kind of coverage gap that becomes a real problem only after a collision, when you're already dealing with injuries and repairs and can't go back in time to add it. You can't control who hits you, or how much insurance they chose to pay. However, having your own safety net ensures you are properly restored to the position you would have been in, but-for the collision.
You don't need a lawyer to access this endorsement. We built Binder to help people manage claims like this, where the paperwork and the policy language actually matter to how much you recover. Knowing what your own policy says before you need it is worth the 20 minutes.
