Welcome to the Ontario Stone, Sand & Gravel Association

OSSGA is a not-for-profit industry association representing over 280 sand, gravel, and crushed stone producers and suppliers of valuable industry products and services. Collectively, our members supply the substantial majority of the approximately 164 million tonnes of aggregate consumed annually in the province to build and maintain Ontario’s infrastructure needs. OSSGA works in partnership with government and the public to promote a safe and competitive aggregate industry contributing to the creation of strong communities in the province.  Find out more about OSSGA by exploring this site as well as GravelFacts.ca.
