Company History

Mainland Sand & Gravel was founded by Laurie Carlson and his brother Mel Carlson and commenced operations in 1970. At that time, the extent of our operations was a dredged river sand site in Surrey at what is today the Timberland Rd. depot as well as a river sand site on Annacis Island. Realizing there was a demand for sand, gravel and crushed stone products, MSG expanded, opening a number of alluvial sand & gravel pits in the Fraser Valley. These pits were relatively small in size and had a limited lifespan so the company embarked on a mission to locate a larger source of raw material, specifically with access to water for barge loading capability.

The search for a suitable site took over 2 years, resulting in the purchase of the approximately 400-acre site comprising the original Cox Station Lands. Cox Station, originally referred to as Cox Landing, dates back to the early 1900's when it was a landing for paddle wheelers. In the 40's and 50's CN Rail operated a mine on the site, extracting aggregate for railway construction. Even today, Cox Station continues to ship material out on rail cars using the two spur lines located in the quarry.

Once the purchase of Cox Station was complete and the permits acquired, a barge loading facility was constructed on the site. The first barge was loaded in January of 1986. Originally the aggregate shipped from Cox Station was produced from an alluvial deposit of natural sand and gravel. The alluvial deposit was quickly exhausted and in early 1987 Mainland embarked on a new era for Cox Station and the company, commencing drilling and blasting of solid granite.

In 1998 Cox Station hit a milestone, shipping one million tonnes of aggregate into the market place. Since then, it has consistently been one of the top aggregate producing operations in Canada, as reported by "Aggregate & Roadbuilding Magazine". The current permitted reserves put the lifespan of Cox Quarry in the 50+ year range, making it one of the largest permitted reserves for aggregate in the Lower Mainland.

Cox Station has relied heavily on the MSG depots to be the outlet for material shipped into the market place. Over 95% of the material produced at Cox Station is shipped out by barge with the vast majority of that being sent to the MSG distribution depots located along the Fraser River. Timberland Rd. depot (MSG's original sand pit) remains the main distribution point for Cox Station aggregates. The No 6 Rd. depot in Richmond was the second distribution point acquired by MSG in the mid 80's (as a reload site for Cox Station product only). Since then Mainland has expanded it's distribution yards with the additions of the No 5 Rd. depot in Richmond and the Port Kells depot in Langley. Both of these two latest additions also inventory and sell dredged Fraser River sand.

Jamieson Quarry in Abbotsford was added in 2002. Jamieson is a land-based quarry, which ships all of its 100 percent fractured product out by truck, primarily into the Abbotsford, Langley and Surrey markets.

Mainland Sand & Gravel was acquired by Summit Materials on September 4th, 2014 and is now embarking on the next phase of the company's development.

Mainland has enjoyed many years of success and we attribute much of that success to a hard working leadership attitude and the dedication of our employees, many of whom have been with the company long term. MSG extends a sincere thank you to our many customers who support us from those who were around during our humble beginnings to those who are just getting to know us now. We look forward to working with you in the future and are committed to continuing to be "Suppliers Of Quality Crushed Stone Products".
