Black Diamond Cheese Limited is an established Canadian cheese company that has been satisfying cheese cravings since 1933

Founded by Robert F. Hart, it began as Belleville Cheddar Cheese Limited with the purpose of exporting aged Canadian cheddar to a cheese-loving British market.
Though still located in Belleville, Ontario, the name changed to Black Diamond. The significance of the name stems from the cheese-making process. Historically, cheese was dipped in hot wax to prevent mold growth on the rind and reduce shrinkage during aging. Upon contact with the rind, the wax would immediately turn black. A diamond among cheese for flavor and black on the outside – the name Black Diamond was born. Black Diamond was the first brand name for Canadian cheddar.
