Canadian employers wishing to employ a foreign worker in Canada must first obtain authorization from Employment and Social Development Canada (ESDC), otherwise known as a Labour Market Impact Assessment (LMIA). Canadian employers must demonstrate that employing a foreign worker will not have a negative impact on the Canadian labour market in most cases, and that there is currently no Canadian citizen or permanent resident available to fill the position. This is typically accomplished by advertising the position on several venues, thus demonstrating there was no suitable Canadian for the job. A LMIA is a very rigorous and comprehensive process that is subject to a high level of scrutiny from the government, and thus must be completed without errors.
