In late August of 1914, Canada entered the First World War following the unanimous vote of a special session of Parliament. This event occurred amid great exuberance and unanimity, and was marked by parades, decorations, cheering crowds and patriotic speeches. Canada was situated far from the European front lines, and its distant, vast land mass and cold climate also contributed to a feeling of insulation from attack or invasion. However, despite a general feeling of distance from the war's unfolding events, there was a rapidly growing realization that German sympathizers and enemy agents might pose a more immediate threat.
