Quarries and Facilities

Few quarry operators or distributors can match the variety of architectural aggregates produced by Upper Canada. From over a dozen quarries we produce products as diverse as slate, marble, granite and feldspar in a rainbow of colours including white, black, green, buff, pink, red and chocolate. We also run a processing facility where feed from many of these quarries are crushed, screened and packaged for terrazzo, precast concrete, stucco and other industries.

We invite you to learn more about our operations by clicking on a quarry of interest. Each page contains a quarry description, technical information on the rock and photographs.
