My insurance license does not extend to BC, but I am reasonably certain that you will never be able to "find out who is cheapest" by taking a survey of riders. Each rider's particular driving history, location, number of other vehicles, home ownership, use of the vehicle and more enter into the rating process. So, while it is probably a good idea to get a short list of insurance companies that people in your area like, it will be up to each rider to contact an agent and get quotes. Hopefully, there are agents there that can quote multiple companies which helps you in the shopping process.
