What is the practical difference between an LMIA-based and an LMIA-exempt work permit?

Both LMIA-based and LMIA-exempt work permits allow a foreign national to work legally in Canada, but the process to obtain each is different and the implications for employer and worker differ.

An LMIA-based permit requires the employer to first obtain a positive LMIA from Service Canada — a process that involves advertising, documentation, and usually several months. The permit is tied to one employer and one position. The employer bears most of the administrative burden.

An LMIA-exempt permit skips the Service Canada step. The exemption must be grounded in a specific legal basis (such as a trade agreement, intra-company transfer provision, or significant benefit category). The employer still usually provides a support letter to IRCC, but there is no Service Canada advertising requirement and the process is generally faster.

For workers, both types are typically employer-specific unless the exemption category also qualifies them for an open permit. LMIA-exempt permits often have different documentation requirements — you cite the applicable exemption code in the work permit application.

From a planning perspective, employers whose positions are LMIA-exempt can usually hire foreign workers faster and with less administrative burden. However, not every position or worker category qualifies.
