A Labour Market Impact Assessment (LMIA) is a document employers need to apply for with the Employment and Social Development Canada (ESDC) to show the need to hire a temporary foreign worker because no Canadian citizen or permanent resident is available for this position. Once a positive LMIA is received by the employer, they can provide you with a copy of the LMIA confirmation letter and the LMIA number. For certain types of LMIAs, you can apply for an LMIA-based work permit from the IRCC along with your employment contract, job offer and other supporting documents. There are mainly 6 types of LMIAs:  High and low-wage LMIA: these are processed to help apply for a work permit. Employers need to apply for the high-wage stream if the wage offered to the temporary foreign worker is above the provincial median wage; if the proposed wage is lower than the provincial median wage, then the employer should follow instructions for the low-wage stream.  LMIA for primary agriculture positions: these are for employers who hire foreign temporary workers only in occupations and activities related to primary agriculture including seasonal agricultural worker program, agricultural stream, high-wage positions stream and low-wage positions stream.  Global Talent Stream: as part of the Temporary Foreign Worker program, this type of LMIA is intended for Canadian firms to access unique and specialized highly-skilled foreign talents or to fill an in-demand highly-skilled position on the Global Talent Occupation List. Employers applying through this stream must develop Labour Market Benefits Plans and undergo annual Progress Reviews of the aforesaid plans.  LMIA applications to support Permanent Residency: these are for employers who wish to hire highly-skilled foreign workers and support their permanent residence applications. Employers applying through this stream need to make a job offer under Express Entry that meets the criteria for one of the three Express Entry programs (CEC, FSW or FST).  LMIA for academic positions: these are for degree-granting postsecondary educational institutions in Canada to employ foreign academics to meet their teaching and staffing needs while attracting new expertise and knowledge.  LMIA for caregiver positions: these are for employers who wish to hire foreign caregivers in a private residence to provide care for children under 18 years of age or for people with high medical needs, such as seniors over 65 years of age, people with disabilities, chronic or terminal illness.
