The Association of Canadian Advertisers Incorporated (ACA) is a national, not-for-profit association exclusively dedicated to serving the interests of companies that market and advertise their products and services in Canada. Founded in 1914 and incorporated in 1917, membership in the ACA is restricted to advertisers only. Unlike most industry associations, the ACA does not represent just one industry. It cuts across all products and service sectors, and speaks on behalf of over 200 companies and divisions who collectively account for estimated annual sales of $350 billion.

The ACA’s primary goal is to help members maximize the value of their marketing communications investments. Members realize tangible value through a wide array of specialized courses, seminars, publications and communications. Confidential one-on-one advisory services are also available for the asking.

As the voice of the Canadian advertiser, ACA safeguards advertisers' right to commercial free speech and demands an advertising marketplace that is accountable for the value provided to the advertiser. As such, ACA represents the views and concerns of advertisers before government and industry bodies and negotiates with talent unions on behalf of Canadian advertisers. By acting on a wide assortment of concerns and issues, the ACA protects and promotes advertisers' ability to advertise responsibly and cost-effectively.
