Foreign nationals require authorization to work in Canada with some exceptions. You might be eligible for an open/closed work permit depending on your situation and what work you are going to perform in Canada. Some factors that define the nature and type of your work permit are:

• You are the spouse of a skilled worker or a student
• You have completed studies in Canada
• You have applied for permanent residency and are awaiting a decision
• Your office in a foreign nation deputes you to its Canadian branch/subsidiary/affiliate office
• Your work is religious or charitable in nature
• An employer in Canada has offered you a job under the LMIA or LMIAE category
• You have applied for any other immigration program such as an entrepreneur/start-up visa that allows you to work in Canada before your permanent resident application is approved.
