Canada: CertainTeed Canada has received environmental assessment approval from the Nova Scotia Department of Environment and Climate Change for its Antrim Gypsum Project in Halifax County, Nova Scotia. It can now move to the project’s permitting phase and toward construction beginning in 2026.
The subsidiary of France-based Saint-Gobain intends to establish operations in Nova Scotia, where eastern North America’s only known major source of gypsum is located. The company will then strengthen its ability to supply its wallboard plants in eastern Canada and the US with locally mined gypsum.
CertainTeed Canada also recently completed construction on its Kootenay West Mine in British Columbia, which is now operational at full capacity with plans to develop a new railway to connect better to other units in western Canada. The company is also reopening its Amaranth Mine in Manitoba to serve central Canada. These efforts are in addition to a partnership with New West Gypsum to recycle and reuse wallboard in production in Alberta, British Columbia, Manitoba, Ontario and Quebec, which has led to over 1Mt of wallboard being recycled and reused at the Vancouver plant alone.
