There are currently (2008) 3 pits in existence. One active and two being used for storage and processing. There was a fourth pit (Brow Pit) that was closed sometime in the 1920's(?) It was subsequently used as a garbage dump and is now landscaped. There have been several owners of the pits, the most recent being LaFarge Ltd. This was preceded by Steetly Industries (1951 - ?) which operated two pits fronting on Hwy 5, which was in turn was preceded by Canada Crushed Stone (1912 - 1951).
All quarries and their names reflect a continuous operation with the name changes tracking the historical progression of ownership and the several pits which were consecutively and concurrently worked. The pit currently being worked is LafargeDundas North Quarry (from the sign at the entrance 2008).
