MONTREAL—  Transcontinental that prints and distributes local weeklies to households throughout Quebec is suing the City of Montreal over its decision to ban unsolicited leaflets and flyers arriving at Montrealers' doorsteps. Transcontinental says the new bylaw infringes on the company's freedom of expression and citizens' right to information. In a lawsuit filed on June 15 at the Montreal courthouse, the company accused the city of acting in a "discriminatory" and "abusive" manner, and said the bylaw is inconsistent with the provisions of the Environment Quality Act. In April, the city announced that as of next spring, weekly flyer-stuffed plastic bags containing circulars, coupons and local newspapers — dubbed Publisac in Quebec — will be prohibited by default, except for residents who have requested them by means of a sticker on their door or mailbox. How the city of Montreal can dictate what is delivered by Canada Post raises a question for the printing industry a a whole .
