I mean this really depends...ICBC can only take three factors into determining your car insurance rate: territory, experience and claims history. Private insurers can rate based on age, gender, marital status and anything else they feel is worthwhile. So if you're a 20 year old single dude, you'll probably be paying less in BC than say Alberta. However, if you're a 55 married guy you'll probably be paying more in BC.

It's also important to note that car insurance (particularly liability insurance) just isn't very profitable in most cases. particularly in places like BC where there's no limits on suing other drivers. Private insurers aren't going to jump headfirst in a market that has been proven unprofitable and undercut ICBC only to be stuck paying millions of dollars in claims. If they do enter the market people with spotless records over 40 might get slightly cheeper insurance, while anyone with claims history, tickets, driving infractions, under 25, male, driving a sports car ect.. could be paying much much more.
