Simcoe County


Walker operates two limestone quarries and seven sand and gravel pits in the Simcoe area. These locations produce high quality stone and manufactured sands to serve the surrounding areas and the GTA. Materials from our Simcoe sites are ideal for construction, the asphalt and concrete markets, erosion control and landscaping. Our Duntroon Quarry is the exclusive producer of superior-quality limestone bunker sand for Ontario’s high performance golf courses.
