CANADA AND THE WAR AT SEA

1914-1918

The small Royal Canadian Navy patrolled the east coast against the threat posed by German submarines.

At the outbreak of war, the Royal Canadian Navy consisted of only 350 men and the two cruisers obtained in 1910. Britain assumed direct responsibility for defending the sea approaches to Canada. German submarines (U-boats) besieged Britain’s Atlantic lines of communication in an attempt to deny Britain the vital supplies it needed to continue the war.

By 1918, the U-boats also lurked off Canada’s east coast. In response, the navy had grown to more than 5000 men and some 100 small warships, many built in Canada, engaged in important anti-submarine, coastal patrol, and minesweeping operations. Another 3000 Canadians served with Britain’s Royal Navy. Over 150 Canadian sailors lost their lives during the war.
