Zaccutt, I've had my insurance canceled 3 times for mods to my vehicle. Yes cops will inform your insurance company of any mods that you have done and your insurance company will order random vehicle inspections if they suspect anything.
If your vehicle is 15 years or older you can go with the Silver Wheels plan for your custom ride. Runs you about $400-$600 a year but you must be apraised.
BelAir Direct will also cover newer custom vehicles. You can insure the value of the vehicle or parts like wheels, etc. But its not cheap. Like regular insurance on steroids.
I wouldn't recomend fucking around or else some dick might run a red and you get blammed for your "altered suspension" and then get a cheque for $250 for your Mazda that you've put $10 grand into.
Also watch out for the MTO and the Emmisions police. They're yanking plates like crazy, and yes they also inform your insurance company. Look out for easy shit like rub marks in the wheel wells, scrapes on the gas tank, vaccum lines, clear lights, etc.
Have fun and welcome to owning a custom vehicle in Ontario.
