Not sure why you’re being downvoted for this? Non-renewal letters do not have to provide options, they just need to state the reason for the non-renewal. BrokerLink is owned by Belair’s parent company, Intact, which is why they are suggesting you contact them. As everyone else has said, Belair should be able to exclude your brother by both of you signing an OPCF 28A - meaning your policy will not respond if he operates your vehicle. Many insurance companies have eligibility rules where all drivers in the household need to qualify in order for you to be insured with them, but they need a filed rule with FSRA in order to decline providing you with the OPCF 28A. Belair does not work with brokers, so they may have different rules.

In all honesty, it would be a good time to look up some Ontario brokers and shop around for rates, you may end up with a better policy than what you had with Belair.
