For centuries, mustard has been appreciated for its medicinal, nutritive and savoury attributes. G.S. Dunn knows the valuable role mustard has played throughout culinary history, as we have been supplying quality dry mustard products to the most notable names in the global food market since 1867.

Mr. Dunn of Croydon England capitalized on the rich soil of the Canadian Prairies and one of the best deep water ports in Canada when he established his milling operation in Hamilton, Ontario over a century ago. In 2019 G.S. Dunn established a seed procurement and cleaning facility, strategically located in the Canadian Prairies in Bow Island, Alberta.

Today, we are the world’s largest dry mustard miller, distributing to over 110 countries across 6 continents.
