Quarries
In 1856, the Nottawasaga Stone Quarry began operations. It was often called the Nicholson Stone Quarry, after owner and stone mason George Nicholson. Located at Hockley Valley Road and Hurontario Street in Mono Township, the quarry operated until 1925.
In 1879, the Shelburne Stone Quarry began its operations just east of Shelburne. It was commonly known as the Hall Stone Quarry, after the original property owner, William Hall. The quarry ceased operations in 1930.
Did you know? Stone from Hall's Quarry was used locally in the construction of the Orangeville Post Office (see right) and Orangeville Hotel.
Much of the highly-prized limestone was taken out of the county by train. It was used in the construction of Toronto's Old City Hall, the Parliament buildings at Queen's Park, buildings at Exhibition Park, and the Oxford County municipal building.
In recent years, the opening of new quarries has been met with opposition in favour of natural preservation and conservation.
