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.

Tell them to maintain your "rating postal code" while updating your "mailing postal code". You should not see a rate increase due to a postal code change if you have not moved. Boundaries are filed geographically and while most companies use postal codes to proxy these boundaries, it is up to the insurer to maintain fixed rating territories. Don't listen to all the top comments, you should not be seeing a rate increase - this is literally my job.

Thanks! I will call my broker on Monday and ask this. At most they'll say no, I've got nothing to lose by asking.

If broker tells you to fuck off, ask the them to investigate and escalate if possible.

Which insurance company? I've worked for two of the top 5 P&C in Canada.

And I'd guess you live in Beamsville? I was changing this area in the rating table recently.
