People transferred within a company

The intra-company category allows international companies to temporarily transfer qualified employees to Canada with the aim of improving management efficiency, increasing Canadian exports and increasing competitiveness in foreign markets.

The Immigration and Refugee Protection Regulations and the general provisions of this section govern the entry of persons transferred within a company. It is supplemented by the provisions of international trade agreements for citizens of signatory countries.

Qualified intra-company transferees require a work permit and are exempt from the Labor Market Impact Assessment (LMIA) under R205(a) (exemption code C12) because they bring significant economic benefits to Canada through the transfer of their expertise to Canadian companies. This applies to foreign nationals from all countries, including the General Agreement on Trade in Services (GATS).

Paragraph R204(a) provides the LMIA TMI exemption code for intra-corporate transferees who are citizens of a country that has signed a free trade agreement (FTA) with Canada , namely NAFTA (and similar FTAs), and supplements General Provisions of the Refugee Protection Act.

Inter-company transferees may apply for a work permit under the general provision if they:

are currently employed by a multinational company and seeking entry to work for a parent company, subsidiary, branch or subsidiary of that company;

are transferred to a company that has a qualified relationship with the company in which they are currently employed and who will hold employment in a legitimate and continuing establishment of that company (18 to 24 months may serve as a reasonable minimum guideline);

are transferred to a position in a specialized knowledge capacity as a senior manager, as a senior manager;

have been continuously employed (through payroll or by contract, directly with the company) by the company which plans to transfer them outside of Canada in a similar full-time position (not accumulated part-time) for at least one year over the previous three years. Period of the year immediately preceding the date of the initial request. Extensions may be granted up to the maximum terms of five and seven years mentioned in the Breaks, work permit recovery period and work permit limit section below and in the section on work categories with periods of validity not to be exceeded. Documented time spent outside of Canada during the term of the work permit may be “taken back” to allow the recipient of the intra-company transfer a full five to seven years of physical presence in Canada;

are only coming to Canada for a temporary period;
