Duncor Enterprises Inc. has a full line of crushing and screening equipment that gives us the capability to crush and size granite, limestone, and bank gravel, and screen various sands and topsoil.

Easy mobility allows our experienced crews to relocate as required, and make a variety of customized products to suit our customer’s needs.


From our Seguin Quarry in Humphrey ON. In the District of Parry Sound, Duncor supplies a variety of granite products, such as screenings to Gabion for the local contractor, various classes of aggregate for our surface treatment operations, screenings for our micro-surfacing and slurry seal, plus material suitable for Asphalt Mix Designs.

 The Topsoil Store, located in Barrie ON, provides an unlimited supply of screened and unscreened topsoil.

Both locations offer the option of customer pick up or delivery.

 Quality Control

Duncor’s in house certified Type C Laboratory allows us to constantly monitor products to ensure quality is maintained and material remains within provincial specifications during the entire crushing/screening process.
