    Canada and the Development of the Polio Vaccine

    During the first half of the 20th century, poliomyelitis, a.k.a. polio or “The Crippler,” hit Canada harder than anywhere else. Successive polio epidemics peaked in a national crisis in 1953. By that time, however, scientists at Connaught Medical Research Laboratories of the University of Toronto had made key discoveries that enabled American medical researcher and virologist Jonas Salk to prepare the first polio vaccine. Connaught Labs also solved the problem of producing the vaccine on a large scale. Canada went on to play an important role in the development of the oral polio vaccine and international efforts to eradicate the disease.Click here for definitions of key terms used in this article.

    Canada and the Manhattan Project

    Canada helped develop the world’s first nuclear reactors and nuclear arms. During the Second World War, Canada participated in British research to create an atomic weapon. In 1943, the British nuclear weapons program merged with its American equivalent, the Manhattan Project. Canada’s main contribution was the Montreal Laboratory, which later became the Chalk River Laboratory. (See Nuclear Research Establishments). This Allied war effort produced the atomic bombs dropped on the Japanese cities of Hiroshima and Nagasaki in 1945. It also led to the development of Canada’s nuclear energy industry.

    Canada’s First Medical X-ray

    On Christmas Day 1895, a young man was shot in the leg during an altercation in Montreal. His surgeon was unable to locate the bullet by exploring its entry site. When the wound began to cause trouble, the surgeon wondered if a remarkable new discovery, X-ray imaging, might be able to locate the projectile. He turned to physicist John Cox for assistance, leading to the performance of Canada’s first medical X-ray examination on 7 February 1896. This event marked the introduction and subsequent dissemination of a new tool to diagnose and treat patients in Canada.

    Canadarm2

    Canadarm2 is a remote-controlled Canadian robotic arm used on the International Space Station (ISS). Canadarm2 was designed as a successor to the robotic Canadarm, which was the mechanical arm used during NASA’s Space Shuttle Program from 1981 to 2011. The design of Canadarm2 is a foundation for creating new generations of robotic arms, including the future Canadarm3. Canadarm2 has reinforced Canada’s global leadership in space robotic systems.
