If you're male and under 25 in Ontario, you're going to get dinged hard. It sucks, but it's the way the system's setup. Other than complaining to your MPP about enacting change, you're mostly out of luck. If you're in a large urban area like Toronto, it's also going to hurt since you're paying for other people's accidents. Here's a map from Kanetix to give you an idea of insurance rate differences across Ontario.
All factors of geography that affect car insurance prices conspire against Brampton. The best policy rate available for a 35-year-old man who drives an 8-year-old sedan and has no marks on his driving record $1,845 annually. Compare this to the same drive, but change the location to Guelph, 70 km to the west. The Guelph driver saves over $800, almost half the premium for the same insurance.
Keep in mind that the minimum car insurance coverage required is determined by the Government of Ontario and may vary in comparison to Alberta, New Brunswick, Newfoundland/Labrador, Nova Scotia, Prince Edward Island, and Quebec. In addition, premiums can vary depending on the area in which you reside, typically being higher in major urban centres, such as Toronto.
