The validity of a Labour Market Impact Assessment (LMIA) in Canada depends on the specific details outlined in the LMIA approval. That is the type of job offer and the duration of the work permit.
In general, an LMIA is valid for six months from the date of issue. LMIA validity is generally linked to the specific job offer and the conditions specified in the approval.
However, the duration of the work permit can vary depending on the type of work permit and the job offer. For example, if you are applying for a work permit under the Temporary Foreign Worker Program (TFWP), the duration of your work permit will depend on the duration of your job offer.
If your job offer is for a period of two years, your work permit will be valid for two years. If your job offer is for a period of six months, your work permit will be valid for six months.
