During your stay
Prior to your departure, you may want to consider registering for the Canadians Abroad Service.
Registering allows the service to contact and assist you if there is an emergency while you are abroad.
Visit the Foreign Affairs and International Trade Canada website for more information about this service and how to register.
If you have purchased travel insurance, your policy will likely include a 24/7 emergency assistance service to help you locate care and coordinate payment. Be sure to have their phone number with you at all times.
Make sure that your passport is valid for the duration of your stay.
Many countries require that your passport be valid at least six months after the due date of your return.
