Ontario's aggregate resources are the sand, gravel, clay, earth and bedrock that underlie our natural landscape.


Aggregates play a significant role in the everyday life of all Ontario residents. They are an integral part of our roads, sidewalks, sewers, subway tunnels and airports, as well as our homes, offices, hospitals, schools and shopping centres. Aggregates are critical ingredients in a number of manufactured products such as glass, coated paper, paint and pharmaceuticals. Aggregates are also used in several manufacturing processes, including the making of steel, aluminium and plastic.


Did you know that aggregates are also found in fertilizer, floor coverings and even toothpaste?


Most of the aggregate resources produced in Ontario are used for construction. Construction aggregate generally includes any combination of sand, gravel and stone in their natural or processed states. 
 

Aggregate Resource Conservation

The Ministry of Natural Resources (MNR) encourages the reduction, reuse, and recycling of aggregate materials.
