How long can a federal government be in power until the are called to an election?

In Canada, a federal government can serve a maximum of four years between elections, as mandated by the Canada Elections Act. However, elections can be called earlier under certain circumstances, such as a vote of no confidence or if the Prime Minister requests the Governor General to dissolve Parliament. In practice, elections have been held more frequently than every four years, often due to political strategy or shifting public sentiment.
