A Labour Market Impact Assessment (LMIA) is a document that a Canadian employer generally must obtain from Employment and Social Development Canada (ESDC) before hiring a foreign worker for most employer-specific positions. Its purpose is to confirm there is a genuine need for a foreign worker and that no Canadian citizen or permanent resident is available and qualified to fill the role.
What the process typically involves
An employer must usually demonstrate genuine recruitment efforts within Canada — advertising the position for a minimum period through specified channels — before applying for an LMIA. The application itself requires details about the job, wages, working conditions, and the employer's business, and is assessed against the impact hiring a foreign worker would have on the Canadian labour market in that occupation and region.
A positive vs. negative LMIA
A positive LMIA confirms the employer can proceed with hiring a foreign worker for that specific position, and the worker then uses it to support their own work permit application. A negative LMIA means the employer has not demonstrated the need, and the position generally cannot be used to support a foreign worker's application as filed.
When an LMIA isn't required
Not every employer-specific work permit needs an LMIA. A range of LMIA-exempt categories exist under international agreements, intra-company transfers, significant benefit provisions, and certain reciprocal employment arrangements, among others. Determining whether a specific role qualifies for an exemption requires matching the job and the worker's circumstances against the specific exemption category — this is often where employers unfamiliar with the system either miss an available shortcut or, conversely, wrongly assume an exemption applies.
What employers should plan for
LMIA processing involves government fees, defined recruitment timelines, and processing time that varies by stream and region. Employers hiring foreign workers regularly should build LMIA lead time into their hiring plans, and should keep thorough records of recruitment efforts, since these are exactly what's scrutinized if an application is questioned.
