As a driver, you can't control these particular changes, but you can control maintaining a clean driving record. Next to comparing rates, this is the best way to keep your auto insurance rates down. However, note that your rates can also increase or decrease if you move, change your commuting time, get a new vehicle, add another driver to your policy, and so on.
To begin with, you (and all drivers you wish to include in the policy) must have a valid driver's license and be a resident of Canada. Next, insurance companies will look at your prior driving record to determine eligibility and rates. However, rates will vary depending on whether you are looking for a new insurance policy altogether or if you wish to renew an existing one. Other eligibility restrictions may arise from past convictions. This too, will vary depending on when your last conviction occurred and the nature of the conviction.
