Not in Ontario. Every insurance company that sells auto insurance in Ontario is required to get approval from the provincial regulator, FSRA, whenever they want to change their rates. They can do this at a maximum of 4 times a year. Some things that could change your rates overnight include accidents, tickets or inaccurate information on your policy like your birthdate.
