History and company information


Windsor Salt was founded in 1893 as The Windsor Salt Company by three employees of the Canadian Pacific Railway. It was also known as The Canadian Salt Company, Limited (French: La Société Canadienne de Sel Limitée) for a time. Since 1954, it has been owned by Morton Salt, which in turn used to be owned by German chemical company K+S, and the company is Canada's largest salt manufacturer.

The company is headquartered in Pointe-Claire, Quebec.[3] It employs over 800 people in its three regional sales offices, three evaporated salt plants, three rock salt mines, and throughout a network of warehouses and salt storage facilities.[4]

In 2020, Windsor Salt's parent, K+S, sold Windsor Salt and Morton Salt to Kissner Group, which is controlled by Stone Canyon Industries Holdings (SCIH) and Mark Demetree.[5]



Windsor Salt recovers, processes, imports, and distributes over 200 evaporated and rock salt products under multiple brand names, including Windsor, Safe-T-Salt and Fino. The company's evaporated salt products are used in household and food products, as well as for agricultural, water softening and industrial purposes. Windsor Salt sells table salt, household salt, Kosher salt, pickling salt, water softening pellets, seasoning, himalayan pink salt, and sea salt.[6]
