The document discusses Ontario's aggregate resources such as sand, gravel, and stone. It notes that aggregate is a non-renewable resource that is essential for infrastructure development and the economy. Ontario uses over 150 million tonnes of aggregate annually, with 60% used for roads and 50% used by the public sector. Aggregate extraction supports thousands of jobs and billions in economic activity. The document calls for balancing aggregate extraction with environmental and social concerns through resource management strategies like land use planning, regulation, and resource conservation efforts.
