Insurance rates are always changing. Take car insurance, for example. In many provinces, rates change every three months. Car insurance companies typically apply to their respective regulating board to have their rates either increased or decreased. This means that even if you were getting the best rate two years ago, you might not be getting the best rate today. It's just the nature of the car insurance industry, which is why these same regulating boards recommend drivers shop around and compare rates from at least three different car insurance companies before purchasing a policy.
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.
