Partner got a dui - should he just cancel his insurance?

We live in Ontario and my partner just got a DUI a few nights ago. He did not hit any other vehicles or people but did damage city property. His vehicle completely flipped over and all air bags went off so it should be a total write off. His car is impounded for 7 days and his license is obviously suspended. His insurance isn’t going to pay for anything with the car, so should he just cancel his insurance all together? They’re going to drop him anyways but he’s trying to save the $600 for his insurance payment that comes out on the 26th.
