A Labour Market Impact Assessment (LMIA) is a document that an employer in Canada may need to get before hiring a foreign worker.
A positive LMIA will show that there is a need for a foreign worker to fill the job. It will also show that no Canadian worker or permanent resident is available to do the job. A positive LMIA is sometimes called a confirmation letter.
