Generally in order to hire a foreign national worker in Canada, employers require government approval before the hiring can take place. That approval is called Labour Market Impact Assessment (LMIA). In order to receive LMIA, the employers must show that have a positive or neutral effect on Canadian Labour Market. Also it would require showing that no qualified Canadian workers were passed up in favour of the foreign worker. All Canadian employers must provide evidence that they have attempted to find qualified Canadian citizens or permanent residents to fill job positions before turning to foreign workers. In addition, employers may be inspected for compliance with government regulations after their employee has begun working in Canada.
Below are some key points to hire employees on the basis of following categories:-

i. Advertising Requirements
ii. LMIA Advertising Exemptions
iii. Global Talent Stream
iv. Owners & Operators
v. Quebec Acceptance Certificate (QAC)
