Established in 1958

Owen Sound Ledgerock Limited was founded in 1958 by brothers Harold and Ralph Stobbe as a way to provide material for their home building business. As time went on, demand for stone increased to the point that Ledgerock became the sole business focus for the brothers.

Today, Owen Sound Ledgerock is seeing the third generation involved in the family run business. The company has evolved from making basic flagstone and split faced products to custom-cut carvings and everything in between. Using modern CNC technology and the latest in software and cutting-edge sawing systems, Owen Sound Ledgerock can make the stonework of your dreams a reality.
