Activities in outer space, like traditional activities in the domains of land, sea and air, can affect the peace and security of the international community on Earth.
Outer space remains the last domain in which humans have not placed weapons. Canada's goal is to ensure secure and sustainable access to, and use of, space, and freedom from space-based threats.
We are unlikely to achieve this goal in one giant leap. Our aim is to progress through small, practical, achievable steps that create preconditions for a climate in which nations and others consider space weapons to be marginally useful. Non-proliferation, arms control and disarmament in outer space have evolved partly through international treaties (multilateral agreements) negotiated by the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS).
