Do I have to find a new Insurance policy by law?

hen I purchased my home, one of my bank's mortgage conditions was that I have to buy home insurance to protect my home from any unforeseen damage. Recently however, the company with whom I've had an arrangement with for those purposes has decided to terminate my policy. I was wondering if I had to go find a new insurance policy, or if I could just stay insurance-less. Would I get in trouble with the bank if I just chose to have no insurance policy with my bank? If it helps, I'm in Canada.
