MONTREAL—  Transcontinental is scrapping Publisac the flyer bundles that is distributed to 2.5 million households in Quebec as part of a shift to a thin leaflet delivered by Canada Post. Weekly newspapers across Quebec depended on the door-to-door Publisac service to bring local news to Quebecers’ doorsteps, packaged in a plastic bag alongside grocery store flyers.For over 45 years Transcontinental’s Publisac , a plastic bag stuffed with flyers, coupons and sometimes a local newspaper delivered to 3½ million householders in Quebec. Montreal's City has put in place new rules that ban the delivery of advertising flyers to homes unless the homeowners signal they want to receive them. The move reverses the current system, where flyers are delivered to every household except those who opt out by slapping a special “No flyers”. Transcontinental  Canada's largest printer started in the flyer business.
