Ault Foods Limited was a Toronto-based dairy processor and Canada's largest dairy company acquiring other dairy companies across Canada. The company was established around 1926.[1] Ault sold off parts of their business in the mid-1990s; milk division (Sealtest Dairy and Silverwood Dairy) was sold to Agropur. Ault itself was acquired by Parmalat in 1997 and the name ceased to exist.
