All visitors to Canada should have a passport valid for longer than the intended period of stay. Travelers from the UK, US, EU, and all British Commonwealth countries do not require a special visa to visit Canada. Tourists are issued with a visitor’s visa on arrival if they satisfy immigration officials that they have a valid return ticket, and that they have sufficient funds for the duration of their stay.
Visitors can stay up to six months, but to extend their stay they must apply to Citizenship and Immigration Canada in Ottawa before expiration of their authorized visit. As visa regulations are subject to change, it is wise to check with the nearest Canadian Consulate, Embassy, or High Commission before leaving home or buying tickets.
Anyone under the age of 18 who is traveling unaccompanied by an adult needs a letter of consent from a parent or guardian giving them permission to travel alone.
