Check out our frequently asked questions for insights into our operations, environmental practices, and community involvement.
A: The Lafarge Dundas Quarry annually produces 3.5 to 5 million tonnes of high-quality crushed stone products. These materials are primarily used in construction projects within a one-hour drive from the quarry, supporting infrastructure such as homes, hospitals, schools, highways, and more. Additionally, the Hamilton steel industry uses over half a million tonnes annually for flux production, contributing to the local economy. We also supply steel, glass manufacturing, automotive, and agriculture industries.
A: The Lafarge Dundas Quarry operates year-round, 24/7. Production takes place for nine months, with the remaining three months allocated for maintenance. Shipping occurs year-round from the south side of Highway #5, typically from 6 am to 5 pm, Monday to Friday, during the high season.

A: The Lafarge Dundas Quarry is situated within the Guelph and Lockport Formations, dating back to the Silurian Period. The extracted rock is bituminous dolomitic limestone, with the upper bench being metallurgical grade limestone from the Guelph Formation, highly valued by the steel industry. The lower bench consists mainly of dolostone from the Eramosa Formation. While fossils are relatively scarce, the quarry is rich in minerals, primarily located in contact areas between limestone and dolostone. Some of the minerals found include Calcite, Celestite, Fluorite, Gypsum, Sphalerite, Galena, Pyrite, Marcasite, Quartz, Selenite, Strontianite, Dolomite, Chalcopyrite, Pyrrhotite, Aragonite, and Melanterite. Specimens from this quarry have been displayed at institutions like the Royal Ontario Museum (ROM) and the Earth Science Museum at the University of Waterloo.
