Natrel has begun a new campaign for its fine-filtered and lactose-free milk. The campaign, developed by JWT Montreal, consists of three 15-second television commercials airing in Ontario and Quebec on major networks. The new executions are an extention of the brand's "Make My Day" campaign from last fall. The creative features people drinking glasses of milk displaying icons including a heart, a party hat and a thumbs-up. Media work for the campaign was handled by Bos.
