History Unit 3: The Modern Era Gouzenko

Igor Gouzenko was a cipher clerk at the Soviet embassy in Ottawa who defected to Canada in 1945.

Gouzenko disclosed classified information about Soviet cyphers, atomic research, and other sensitive matters.

Gouzenko's defection raised concerns about Soviet espionage and the potential compromise of valuable information.

Based on Gouzenko's information, Canada arrested and convicted individuals involved in espionage activities.

Canada used the War Measures Act to arrest suspected Soviet agents, demonstrating its response to the security threat.

The Gouzenko Affair led to investigations and counter-espionage actions in the United States and the United Kingdom.

Canada played a significant role in the Korean War, contributing troops to the United Nations forces supporting South Korea.

The United Nations Charter established the Security Council, General Assembly, Social and Economic Council, and International Court to promote global peace.

The DEW line (Distant Early Warning) was a network of radar stations designed to detect incoming aircraft from the Soviet Union.

Indigenous people were relocated to the high Arctic to improve their hunting opportunities.

Both Canada and the United States funded the creation of the DEW line, demonstrating their joint effort in protecting the Arctic.

Canada's support for South Korea against communist forces, particularly from North Korea and China, reflects an early instance of its Cold War involvement.

The UN Charter created four key organizations: the Security Council, General Assembly, Social and Economic Council, and International Court.

The Cold War fear of a Soviet attack from the Arctic prompted the creation of the DEW line.

Canada actively contributed troops to the United Nations forces during the Korean War, supporting South Korea against communist aggression.
