About this work
What is an LMIA actually deciding?
Whether hiring a foreign national will have a neutral or positive effect on the Canadian labour market. It is a labour market question, not an immigration one, and it is decided by Service Canada on behalf of Employment and Social Development Canada rather than by Immigration, Refugees and Citizenship Canada.
That split matters because it means two separate applications with two separate decision makers. A positive assessment does not grant a work permit. It gives the worker something to apply with, and the permit application can still be refused on grounds the assessment never looked at.
The employer pays $1,000 for each position requested and cannot pass that cost to the worker. Any arrangement that has the worker paying for their own assessment is a compliance problem for the employer before it is anything else.
