A Labour Market Impact Assessment (LMIA) is a document issued by Employment and Social Development Canada (ESDC) that an employer must obtain a positive LMIA before they can hire a foreign worker for the purpose of filling the labour shortage where no Canadians or Permanent Residents can perform the job for that occupation. An employer, except for occupations that do not require a LMIA, must send an application to ESDC for consideration. A foreign worker may apply for a work permit with the confirmation letter (positive LMIA) that will allow a foreign worker to enter Canada, as long as a foreign worker is inadmissible to Canada. Service Canada assesses LMIA applications and makes decision whether they accept or refuse after assessment of each particular case. There are several factors that Service Canada takes into consideration before issuing a confirmation letter. The process of LMIA is complicated and has been amended to make it difficult for employers to hire foreign workers from overseas unless all requirements as set out by ESDC meet the criteria. It is strongly recommended to hire a LMIA expert who can provide you guidance and advice with respect to LMIA application.
