Canada is a signatory to numerous multilateral and bilateral agreements with partner countries that include sections on the movement of labour between countries. Most popularly, Canada is a signatory to the United States, Mexico, Canada Agreement (USMCA). As the successor to the North American Free Trade Agreement (NAFTA), the sections governing work permits and skilled labour remain largely the same. Free trade agreements facilitate the movement of workers who are intra-company transfers, professionals, and various business visitors such as those providing after-sales service. As an employer, you may be exempt from completing a Labour Market Impact Assessment (LMIA) for certain categories of workers and jobs. There are more than 60 occupations, mostly in skilled work and workers may apply for admission upon arriving in Canada if they meet the requirements.
