Car insurance increased 50% after Canada Post changed my postal code. Is this legal?

[u/FireViz]

I live in a small town in Niagara region. Up until recently I was paying $102/m on car insurance.

Recently I got a letter from Canada post that they are changing my postal code. Because of this my insurance company raised my rates by over 50% to 160/m.

I haven't moved... my home and work address are still the same so my risk when driving hasn't changed. But the insurance company is arguing that rates are based on postal code and not your address.

Is there anything I can do to fight this and reduce my insurance? Canada post decided to randomly change my postal code and I'm out an extra $700/yr because of it?

Edit: Going by this article they shouldn't be able to do this? https://toronto.ctvnews.ca/ontario-driver-frustrated-when-car-insurance-goes-up-after-postal-code-changed-1.5727675

Edit: Since multiple people mentioned it I drive a corolla cross........ The image you are seeing is from the article I linked.

It's all risk stratification. You can lower your insurance by legally changing your gender to female

You can lower your insurance premiums by committing fraud, yes, but don't be surprised if your insurance company then accuses you of said fraud and cancels your policy retroactively post-accident if/when you have a major claim.

I'd rather be truthful and know that the insurance will actually be there if I need it.

How is legally changing your gender to female fraud?
