Two major fast-food chains in Canada plan to begin serving all-day breakfast at most of their outlets next month. Canadians craving a dinner-time Egg McMuffin will be able to buy one starting February 21st, when McDonald’s Canada extends its breakfast hours until close at about 11-hundred of its 14-hundred-and-50 restaurants. And A*W Food Services will launch its program the next week at most of its 879 Canadian stores. Both companies say customer demand drove the decision to offer limited breakfast menus all day long and market tests have been positive.
