Note: If you have an open work permit (e.g. post-graduation work permit, International Experience Canada, et cetera) your spouse must attach a copy of your work permit to their application for an open work permit, along with a:
- letter from your current employer that confirms you work there in a NOC 0, A or B occupation, or a copy of your employment offer or contract, and
- copy of your recent pay slips.
