A positive LMO will show that there is a need for a foreign worker to fill the job and that no Canadian worker can do the job. A positive LMO is sometimes called a Confirmation letter.
Your proposed employer must contact Human Resources and Skills Development Canada , now called Employment and Social Development Canada (ESDC). HRSDC will provide details on the LMO application process.
In some cases, you may not need a LMO to apply for a work permit.
