Aggregates, also known as mineral aggregates, are a valuable non-renewable resource essential to Waterloo Region's growth and economic prosperity. Aggregate resources include naturally occurring sand and gravel deposits. These resources are needed in the building industry, and are used to produce a wide range of manufactured items, including blocks, bricks and pre-cast concrete products and asphalt.

Waterloo Region is one of the largest aggregate producers in southwestern Ontario, providing several million tonnes of aggregates annually to local and provincial markets. As the region's population continues to grow, so does the demand for aggregate products to support building and construction needs.

The Region of Waterloo has developed policies to help reduce or minimize the potential impacts of aggregate removal practices on the environment, especially our surface water and groundwater resources, and the surrounding rural and urban communities.

More in-depth information about the Region's polices related to aggregates can be found in Chapter 9 of the Regional Official Plan.
