All Canadian passports are issued by the Passport Program of Immigration, Refugees and Citizenship Canada (IRCC). Prior to 1 July 2013, Canadian passports were issued by Passport Canada, an independent operating agency of Foreign Affairs and International Trade Canada. They are normally valid for five or ten years for persons 16 years of age and older, and five years for children under 16. In 2015, 67 per cent of Canadians had passports, and 22.88 million Canadian travel documents were in circulation as of 31 March 2015.
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.
