Black Diamond Cheese
Black Diamond Cheese Limited is a cheese manufacturing company in Canada. Black Diamond employs approximately 470 people at its factory in Belleville, Ontario, and its products can be found at most major retailers in Canada. The company has been owned by Parmalat Canada since 1998. In the United States, the brand is licensed to DCI Cheese in Wisconsin.
Black Diamond was established in 1933 by Robert F. Hart. Founded under the name "Belleville Cheddar Cheese Limited", its original purpose was to export aged Canadian cheddar to the British market. Black Diamond was purchased by Brooke Bond in 1968. In 1984, Brooke Bond became part of Unilever, which divested Black Diamond to Canada Packers in 1987. Canada Packers then sold the plant to major dairy Ault Foods in 1991, which after several divestments was sold to Parmalat Canada in 1997.
