As a general rule, work permits apply to a specific employer. If an individual changes employers he or she must apply for a new work permit. Only workers admitted to Canada on an open work permit can change employer without reapplying. Open work permits are the exception and may be available to the spouses/common law partners of certain work permit holders, the spouses/common law partners of foreign students in Canada, asylum seekers, in-land sponsored family members, and destitute students in Canada.
