    Canada and the Movement to Ban Land Mines

    In the mid-1990s, Canada became a global leader in the effort to eradicate land mines, which are explosive and deadly weapons. In December 1997, representatives from 122 countries assembled in Ottawa to sign the Mine Ban Treaty (or Ottawa Treaty), which came into force on 1 March 1999. With over 80 per cent of the countries in the world having signed the treaty, it is one of the most widely accepted. The Canadian government continues to support demining efforts globally by assisting in related United Nations operations, supporting organizations like the International Campaign to Ban Landmines, and providing training, education and funding for mine clearing.

    Prestonian-class Frigates

    The Prestonians were a group of 21 Second World War frigates reactivated by the Royal Canadian Navy (RCN) in the 1950s for antisubmarine warfare (ASW). This was a stopgap measure to meet Canada’s North Atlantic Treaty Organization (NATO) force goals until the purpose-built St Laurent-class destroyer escorts came into service. Although originally built as Anti-Submarine Warfare (ASW) vessels, the Prestonians had to be extensively modified to meet the more complex demands of Cold War ASW, which they performed until withdrawn in the mid-1960s.

    Radar

    Radio waves are part of the electromagnetic spectrum, as is visible light. H.R. Hertz provided practical demonstration of Maxwell's theory and, in 1888, actually performed radio-wave-reflection experiments.

    Ross Rifle

    In the early 20th Century, the Ross rifle, a Canadian-made infantry rifle, was produced as an alternative to the British-made Lee-Enfield rifle. The Ross rifle was used during the First World War, where it gained a reputation as an unreliable weapon among Canadian soldiers. By 1916, the Ross had been mostly replaced by the Lee-Enfield.

    Ships of the War of 1812

    The war on the water was an essential, if not the most important, aspect of the WAR OF 1812. Great Britain was obviously at a disadvantage geographically when trying to defend its colony Canada in a conflict with the United States.

    St Laurent-class Destroyer Escorts

    The St Laurents were developed in the early Cold War as a high-speed, long-range antisubmarine frigate to counter the growing Soviet conventional submarine threat. They were the first major warship class designed and built in Canada and incorporated many ground-breaking features, earning them the nickname, the “Cadillacs.” Seven St. Laurents were built. The success of the design inspired a succession of follow-on classes: the Restigouche, Mackenzie and Annapolis classes. A total of 20 ships — all named after Canadian rivers — were built around the same hull configuration and propulsion plant. These iconic ships were the mainstay of the Canadian fleet from 1955 to 1995, including most of the Cold War.

    UFOs in Canada

    For 45 years, the Canadian government investigated unidentified flying objects (UFOs). Several of its departments and agencies collected sighting reports of UFOs in Canadian airspace from 1950 to 1995. These investigations started during the Cold War, spurred by fears of Soviet incursions. What began as a military question eventually became a scientific one. From the start, however, the government was reluctant to study this topic. It devoted few resources to it, believing UFOs to be natural phenomena or the products of “delusional” minds. By contrast, many Canadian citizens were eager for information about UFOs. Citizens started their own investigations and petitioned the government for action. In 1995, due to budget cuts, the government stopped collecting reports altogether. For their part, citizen enthusiasts have continued to investigate UFOs.
