Not sure if it is the same on both sides of the border or even from one insurance company to the other but here's my story. I got a quote from TD General Insurance that was by far the cheapest and at one point I asked a question about my son who was 14 at the time. As soon as they heard that I had a son that was over 12 but too young to have a driver's license they wouldn't even insure me until he got the Ontario Snow Vehicle Opertor's Permit. I asked if I could insure it just for me and they said 'No, as long as there is a child that is old enough to ride they won't give the adult insurance unless the child is certified'. I don't think it affected the price at all, they just wanted to cover all bases. Then when my second son turned 12 he had to take the course too. So if you have a son or daughter who will never drive, do not even mention it or they could force you to get them certified. If they will drive, make sure the insurance company knows and do what you gotta do.
