Gillis Quarries Limited (GQL) was incorporated in 1922. Founded in 1910 by August Gillis, this fourth generation company is built on industry-leading customer service, product quality and need satisfaction.
GQL began on a small scale and has grown over the last 100 years into one of Canada’s largest dimensional stone quarries, specializing in the fabrication of Tyndall Stone®, a wonderfully unique, mottled, fossilized, natural stone. This rare dolomitic limestone deposit discovered in Garson, MB in 1894 has given birth to some of the most beautiful buildings in modern history.
Canada is the only source in the world for this stone, geologically referred to as the Upper Mottled Limestone of the Red River Formation of the Ordovician System of the Paleozoic Era.
Gillis Quarries Limited is a people oriented company. Our long term, multi- generational, experienced team is committed to providing the very best in natural stone solutions.
