The Ontario Trucking Association is the leading voice of the for-hire trucking industry in Ontario and also plays a pivotal role in the national group, the Canadian Trucking Alliance. Founded in 1926, OTA provides services and public policy advocacy for thousands of companies which together represent over two-thirds of all commercial tractor-trailers on Ontario roadways and employ over 70,000 men and women. OTA members consist of trucking companies from every Canadian province, as well as the United States and it is the only trucking association that represents all segments of the industry, including for-hire carriers, private carriers, intermodal, and suppliers. Fleet sizes of member carriers range considerably. In fact, most OTA carriers are small-medium, family owned-businesses with half of membership consisting of fleets with less than 25 power units.
