On November 16, 2022, IRCC is switching to the 2021 version of the National Occupational Classification (NOC).
If the province or territory will get your application on or after November 16, 2022, you must use the 2021 version of NOC.
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.
Once an employer gets the LMIA, the worker can apply for a work permit.
