As of January 1, 2009, "Minimum National Advertising Standards" were adopted by Human Resources and Skills Development Canada ("HRSDC") and Service Canada ("SC").

On May 2010, HRSDC and SC published a further notification indicating that all occupations based on the National Occupational Classification ("NOC") system, skill levels 0, A, B, C and D, are subject to the Minimum National Advertising Standards. Failure to comply with the requirements will result in the application for a Labour Market Opinion being denied.

Employers seeking to hire Temporary Foreign Workers must be prepared to demonstrate that they have met the minimum advertising requirements by providing proof of advertisement and the results of their efforts to recruit Canadians or permanent residents. This proof includes copies of advertisements, the number of Canadian applicants, and why they were rejected. Records of the recruitment efforts must be kept for a minimum of two years, in the event that the government authorities contact the employer to verify their advertising efforts. Under certain provincial and federal legislation, records must be kept for a minimum of six years, such as under the Income Tax Act.

Employers have been encouraged to conduct ongoing recruitment efforts, including efforts among under-represented groups that face barriers to employment such as Aboriginal peoples, older workers, immigrants/newcomers, persons with disabilities, and youth. The advertisements may be on recognized internet job sites, in local and regional newspapers, at community resource centres and in local regional employment centres.

The advertisement criteria does vary slightly in the Province of Quebec.

Minimum National Advertising Standards

For NOC 0 and A occupations, the minimum advertising efforts required were set as the need to advertise on the National Job Bank (or the equivalent in Saskatchewan, Quebec or the Northwest Territories) for a minimum of 14 calendar days, during the three months prior to applying for a Labour Market Opinion; or conduct similar recruitment activities consistent with the practice within the occupation (e.g. internet job sites, journals, newsletters, national newspapers or by consulting unions or professional associations).

For NOC B occupations, the minimum advertising efforts required were set as the need to advertise on the National Job Bank (or the equivalent in Newfoundland and Labrador, Saskatchewan or the Northwest Territories) for a minimum of 14 calendar days during the three months prior to applying for a Labour Market Opinion. The advertisement must include the company operating name; job duties for each position, if advertising for more than one vacancy; wage range (i.e. an accurate range of wages being offered to Canadians and permanent residents), the wage range must always include the prevailing wage for the position; the location of work (business address – local area, city, or town); and the nature of the position (i.e. project based, or permanent position). In Quebec, the employer is expected to advertise on Emploi-Quebec for a minimum of 14 calendar days, or conduct similar recruitment activities consistent with the practice within the occupation during the three months prior to applying for a Labour Market Opinion.

For NOC C and D occupations (including live-in caregivers and seasonal agricultural workers), the minimum advertising efforts required were set as the need to advertise for a minimum of 14 days on the National Job Bank (or the equivalent in Saskatchewan, Quebec or the Northwest Territories) during the three months prior to applying for a Labour Market Opinion; and conduct recruitment activities consistent with the practice in the occupation during the three months prior to applying for a Labour Market Opinion. The employer is expected to advertise for the equivalent of 14 days, choosing one or more of the following options: advertise in newspapers (e.g. a weekly ad during two to three weeks in journals, newsletters, national/regional newspapers, ethnic newspapers/newsletter or free local newspapers; advertise in the community (e.g. posting ads for two to three weeks in local stores, community resources centres, churches or local regional employment centres; advertise on internet sites (e.g. posting during 14 days/two weeks on recognized internet job sites – union, community resource centres or ethnic sites).

HRSDC/SC have reserved the right to require alternative or additional recruitment efforts either beyond the stipulated duration or broader advertisement basis if HRSDC/SC believes that additional effort would yield qualified Canadian citizens or permanent residents who are available to work in the occupation and region.
