How do I change employers if I'm on a closed (employer-specific) work permit?

A closed permit only allows work for the employer named on it, so changing jobs generally means applying for a new work permit — usually with a new LMIA or an LMIA-exempt job offer. In most cases you cannot start with the new employer until the new permit is approved, though IRCC has a process to request authorization to start sooner in some situations. Never work for the new employer before you are authorized. Our Work Permit & Job Support team can explain the steps.
