Ontario’s aggregate industry is a lynchpin of both the provincial and national economy, supplying the essential materials needed to build roads, highways, transit, housing, hospitals and critical infrastructure. As economic uncertainty persists amid ongoing U.S. tariff pressures and trade disruptions, a strong domestic aggregate supply is more important than ever. Through the sustainable extraction and transportation of stone, sand and gravel, OSSGA members help keep construction projects moving, support thousands of well-paying jobs and strengthen Canada’s economic resilience. Ensuring access to aggregate resources and efficient approvals will be critical to maintaining competitiveness, supporting investment and building the infrastructure needed for long-term growth.
