shall stamp the person's passport or travel document. In the case of a temporary resident visa holder, the stamp should be placed, wherever possible, on the page opposite the visa.
69. As a matter of current practice, passports of
Canadians and permanent residents are not stamped. However, if requested, border services officers may stamp passports of Canadians and permanent residents.
Passport Stamping ExceptionsU.S. citizens
70. While it is not a requirement, border services officers are
encouraged to stamp the passports of U.S. citizens. Stamping of passports and travel documents is a best practice and should be done whenever possible.
Cruise ship passengers
71. In situations where foreign nationals exempt from the requirement for a temporary resident visa are disembarking for a port of call visit and they have been authorized to enter Canada and are immediately returning to the same cruise ship, local management will
determine whether border services officers will or will not stamp passports.
72. Passports or travel documents of foreign nationals who require a temporary resident visa must be examined
and stamped at the first port of entry where entry is authorized. Visa-exempt foreign nationals other than U.S. citizens who are disembarking the cruise ship, are not returning to the vessel and have been authorized to enter Canada
must have their passport or travel document stamped.
