The snack was invented after the Second World War by James Marker of Dayton, Ohio and W. T. Hawkins.[2] The pair were living in Chicago when they discovered a method, by trial and error, of extruding cornmeal, casting it into fingerling shapes, then deep frying it in vegetable shortening and sprinkling it with cheddar cheese. Production was moved to Tweed, Ontario in 1949 where the recipe was perfected and the W. T. Hawkins Ltd. plant established.[3]
Production was moved to a factory in Belleville, Ontario in 1956 after fire destroyed the original plant in Tweed.[4] They concentrated exclusively on Cheezies after dropping other snack foods from their portfolio. The snack has been produced in the same facility ever since and continues to be sold across Canada. Marker's original machine is still used to manufacture Cheezies at the company's plant, as of 2012.[3] Marker remained vice president of the W. T. Hawkins Company until his death in 2012.[3]
On September 19 2016, a storage warehouse for W. T. Hawkins in Belleville also was destroyed by fire.[5]
