Employers of some types of temporary workers need to get a Labour Market Impact Assessment (LMIA) before the worker applies for a work permit. An LMIA is a document from Employment and Social Development Canada that gives the employer permission to hire a temporary worker.
If you are an employer, find out if you need an LMIA.
If you are a worker, you can answer a few questions to find out:
the kind of work permit you can apply for, and
the steps your employer needs to take before you submit your work permit application.
