On Wednesday, a last-minute motion led the Toronto City Council to ban plastic shopping bags in this city of 2.5 million. On January 1, 2013, Toronto will become the first major city in Canada to pass a law prohibiting retailers from giving out single-use plastic bags to consumers. The move angered Canada’s leading plastics trade group and caused squabbling within Toronto’s city council, but it was of course cheered by local environmentalists.
