[Ontario] Auto Insurance Renewal Before June 1st

I just received my auto insurance renewal from TD Meloche Monnex for $1,533 annually.

As any good consumer should do, I shopped around and Belairdirect quoted $ 1,113 for identical coverage and deductibles. Is there any reason I should be hesitant of switching? Does anyone have experience with Belairdirect?

The first step I'm going to take, is to call TD and ask if they'll match/beat the offer. Is this something auto insurance providers will do?

Lastly, I've seen that regulations are changing as of June 1st and premiums are expected to drop but will not take effect until the next renewal. My renewal date is May 30th.... Is there anything I can do to see these benefits without waiting another year? Do you think it will be worth it?
