Why were Canadians scared of communism?

Canadians were scared of communism during the Cold War due to fears of ideological infiltration and the potential for a communist revolution similar to those seen in Russia and other countries. The rise of the Soviet Union heightened anxieties about espionage, subversion, and the spread of communist influence in North America. Additionally, the government responded with measures like the Red Scare, which fueled public paranoia and suspicion towards leftist political movements and individuals perceived as sympathetic to communism. This fear was exacerbated by events such as the Korean War and the possibility of nuclear conflict.
