The 65 year-old “Christie’s” factory on the Lake Shore beside the Gardiner Expressway is about to close. The international group controlled by Kraft food said today the place is just too inefficient to renovate . Some 550 employees have been given notice of up to ten months. Their jobs are not likely to be transferred. The plant, originally built by the Canadian firm Christie, Brown is located at Lake Shore Boulevard and Park Lawn Road. It has seen the company change hands and its products, mostly cookies, were the subject of one of the most enduring promotional catch lines ever created — Mr. Christie, You Make Good Cookies. City Councillors say there is plan to build condominiums on the property.
