Canada

In 2000, Canada produced the second-most Mg mineral in the world, and by 2011 it produced none. This may have been the result of the toxic sulfur emission SF6 problem, regulated by the Kyoto accord. Many resources exist in south-eastern British Columbia.

Mines

Baymag produces from magnesite ore in Mount Brussiloff, near Radium Hot Springs, British Columbia, and calcinates the ore into refined MgO in Exshaw AB.
Rossland BC - Gryphon Enterprises purchased an open-pit mining property in November 2017 for $750 million.

Smelters and refineries

Noranda Inc produced Mg from its tailings ponds in Asbestos, Quebec from 2000 for about a decade.
The magnesium smelter in Bécancour, Quebec used to be operated by Norsk Hydro, and was shuttered by 2011.
The Dominion Magnesium Limited smelter in Haley Station, Ontario was the site for the first industrial implementation of the Pidgeon process. It began operation around 1942 and ceased operation before 2010.
