A border services officer at the port of entry in Canada will determine how long you can stay in Canada. Most visitors are allowed a six-month stay from the day they entered Canada. If the officer authorizes a stay of less than six months, they will indicate in your passport the date by which you must leave Canada. If you want to stay longer than your authorized stay, you should apply for an extension at least 30 days before the authorized end of your stay.
