Canada’s Greatest Inventions and Innovations

From the jetliner and the snowmobile to the pacemaker and the Black Berry, Canadians have long been at the forefront of innovation and invention. Canadians are behind a variety of cutting-edge products, life-saving medicines, innovative machines, and fascinating ideas. Although our inventions have typically been created with little fanfare, financing, or expectation of return, they have often gone on to play important roles in day-to-day life. Our "greatest invention" is probably insulin, which millions of people depend on for life and health. But the light bulb, the Canadarm, and the Black Berry certainly vie for that honour as well. Some of our inventions are small: the paint roller, the Robertson screwdriver, and the crash position indicator – the forerunner of the black box on planes. Others are larger: the jetliner, the snow-blower, and the snowmobile. Some, such as Standard Time, are really just complex ideas while others, such as the pacemaker, are triumphs of complex technology. Put simply, Canadians are supremely innovative!
