    Canada and Antisubmarine Warfare during the Cold War

    During the Cold War, the Canadian Navy played a crucial role in antisubmarine warfare (ASW), working closely with its allies to patrol and monitor the North Atlantic and Pacific Oceans for Soviet submarine activity. Canada invested in new technology and continually modernized its fleet of ships and aircraft to better detect and counter Soviet submarines. It also operated strategic warning systems with its allies, particularly the United States. By the end of the Cold War, Canada had developed a very high reputation in the field.

    Canada and Antisubmarine Warfare in the First World War

    When the First World War began in August 1914, the Royal Canadian Navy (RCN) was unprepared to fight a war at sea. Founded only in 1910, it consisted of two obsolete cruisers, HMCS Niobe and HMCS Rainbow, and about 350 regular sailors, augmented by 250 reservists. During the war, it was assigned a growing number of tasks, which it was ill-equipped to perform. This included protecting Canadian coastal waters against German U-boats. The RCN scrambled to find ships and sailors but was ill-equipped to fight enemy submarines, which sank several vessels in Canadian waters in 1918.

    Canada and SOSUS

    The Sound Surveillance System (SOSUS) was a network of passive sonar stations established by the United States Navy (USN) in the early 1950s to “listen” for Soviet submarines. SOSUS was a core element of antisubmarine warfare (ASW) during the Cold War. It developed out of intense postwar oceanographic research into how sound is propagated under water. Given Canada’s shared responsibility for the defence of North America, the Royal Canadian Navy (RCN) was actively engaged in this research and mission and helped operate SOSUS. The mission was highly classified throughout the Cold War and only declassified in 1991. SOSUS became part of the Integrated Undersea Surveillance System (IUSS), a broader network of fixed and towed sensors that remains operational.

    Defence Policy

    Before 1870, the defence of Canada was a costly burden for France and then for Great Britain, invariably against enemies to the south, be they Iroquois, English or the American invaders of 1775-76 (see AMERICAN REVOLUTION) or of 1812-14.

    Exercise Tocsin B

    Exercise Tocsin B was a nationwide nuclear preparedness drill that lasted 24 hours between 13 and 14 November 1961. It was the last of three national survival exercises named Tocsin in 1960–61. It was also the largest and most widely publicized civil defence drill ever held in Canada. This Cold War exercise run by the Canadian Army simulated the impact of thermonuclear warfare in Canada. Its goals were to show how the state would warn Canadians of such an attack and how government would continue during the crisis. By raising popular awareness of the potential for a devastating nuclear attack, Tocsin B showed Canadians what was at stake in the Cold War.
