The Ontario Tire Dealers Association (OTDA) is an industry trade association representing approximately 500+ Ontario tire retailers that sell in excess of 60% of the passenger, light truck, medium truck and agricultural tires sold in the province annually. Our members manage an equivalent amount of scrap or used tires as collected from consumers when they purchase new tires. Our mandate is to promote, educate, and represent members in all areas that impact the growth and prosperity of the tire industry.
