I have replaced the passport under which my Letter of Introduction was issued (because it was damaged/ lost/ stolen/ I got married) and am about to travel to Canada. May I still use the Letter of Introduction to obtain my work permit?
Yes, so long as the validity period of the Letter of Introduction has not expired. When entering Canada, you must notify the officer of this change so that your work permit may be issued in accordance with your current passport information. It is recommended that you bring a photocopy of your previous passport along with your current valid passport for presentation at the port of entry. If you changed your passport because you got married, please also bring a copy of your marriage certificate.
