    Woodward and Evans Light Bulb

    In 1874, Canadians Henry Woodward and Mathew Evans patented a design for an incandescent light bulb. Their invention preceded that of American Thomas Edison by several years. In fact, the second patent (issued in 1876 in the United States) was among those that Edison bought as he refined the technology to create a longer-lasting bulb. Woodward and Evans’s early work on the light bulb in Toronto has gone largely unrecognized. It was nevertheless an important development in the invention of electric lighting.

    Ice Resurfacers (Including Zamboni Machines)

    Zamboni ice resurfacers are used in arenas across Canada and around the world. Although Zamboni is a registered trademark, many Canadians use the term to refer to all ice resurfacers, including those produced by other companies. American Frank J. Zamboni invented the original Zamboni ice resurfacer in 1949. His namesake company is based in Paramount, California, but also has a large manufacturing facility in Brantford, Ontario. The Zamboni Company’s major competitor, Resurfice Corporation (based in Elmira, Ontario), produces the Olympia line of ice resurfacers that are used in arenas across Canada and around the world. In 2016, ICETECH Machines began producing the Okay Elektra, an electronic ice resurfacer, in Terrebonne, Québec.

    Zooarchaeology

     In Canada most zooarchaeologists study teeth, bone and marine shells, because these materials are commonly preserved on archaeological sites. Preservation of specimens depends on what happened to them before burial, the rate at which they were buried, and the burial environment.
