Ad Standards, which was created in 1957, is a national not-for-profit organization that has been administering the Canadian Code of Advertising Standards since 1963. Across the economy and society, they are the stewards of acceptable advertising in Canada. As a not-for-profit they are visible in terms of who they are. For example, the Government of British Columbia, in their oversight mechanism, is also using Ad Standards for their third party review.
Since 2016 they have reviewed just under 7,000 creative pieces for the Government of Canada in 120 campaigns on all manner of topics, from recruitment to health issues, economic action and so on.
