To commemorate the 50th anniversary of the opening of the St. Lawrence Seaway, Canadian Geographic, in partnership with the St. Lawrence Seaway Management Corporation, has produced a poster map of the Great Lakes St. Lawrence River system. A complementary thematic module at The Canadian Atlas Online, illustrating the waterway’s history, current operation and future prospects, will be launched in the fall. In addition, the Canadian Council for Geographic Education is developing 13 bilingual lesson plans for middle-school students — one specific to each province and territory. Students will learn, among other topics, how the locks and channels operate to ship goods, how Great Lakes freighters are designed and how seaway traffic bypasses the Niagara River and Niagara Falls. The lesson plans will be available at The Canadian Atlas Online in November 2009.
