Insurance in Ontario is pretty expensive... even more so if you live in the Greater Toronto Area.
I have a perfect 6-star no claims rating, have a multi-car discount as well as a discount for having my two residential properties with the same company. I only carry $1 million liability and have $400 deductible Collision and $200 deductible Comprehensive coverage.
My current Cadillac CTS costs $2,016 / year. I shop this around every couple of years and have been unable to do any better.
My broker had a bit of trouble looking up the Tesla Model S, but after much discussion and periods of waiting on hold, he came back with an estimate of $2,305 for the exact same coverage. He asked what the car costs and I told him they ranged from $64,500 to north of $100,000 minus the $8,500 EV rebate. I think this estimate is based on the lower end of the price range. He cautioned that this is only an estimate and that he would need the VIN number to work up a quote.
I guess about $300 more a year for a new (more expensive) Model S vs. a 3 year old Cadillac is really not too bad...
