Canada and Weapons of Mass Destruction - Disarmament

Disarmament

Canada is a member of every international disarmament organization and is committed to pushing for an end to nuclear weapons testing, reduction in nuclear arsenals, a ban on all chemical and biological weapons, bans on weapons in outer space, and blocks on nuclear proliferation. However, in recent years it has become less vocal on the issue of disarmament; the need for increased border defense, particularly in the Territories, has recently overshadowed other issues in military circles.

Canada maintains a division of its Foreign Affairs department devoted to pursuing these ends. It also dedicates significant resources in trying to verify that current treaties are being obeyed, passing much information on to the United Nations. In the 1970s, Canada discussed building a reconnaissance satellite to monitor adherence to such treaties, but these plans were shelved. A public furor arose in 1983, when the Canadian government approved a plan to test cruise missiles in Alberta.

Canada continues to promote peaceful nuclear technology exemplified by the CANDU reactor. Unlike most designs, the CANDU does not require enriched fuel, and in theory is therefore much less likely to lead to the development of weaponized missile fuel. However, like all power reactor designs, CANDU reactors produce and use plutonium in their fuel rods during normal operation (roughly 50% of the energy generated in a CANDU reactor comes from the in situ fission of plutonium created in the uranium fuel), and this plutonium could be used in a nuclear explosive if separated and converted to metallic form (albeit only as reactor-grade plutonium, and therefore of limited military usefulness). Accordingly, CANDU reactors, like most power reactors in the world, are subject to safeguards under the United Nations which prevent possible diversion of plutonium. CANDU reactors are designed to be refuelled while running, which makes the details of such safeguards significantly different from other reactor designs. The end result, however, is a consistent and internationally accepted level of proliferation risk.

A common accusation is that India used Canadian reactors to produce plutonium for weapons. India owns two licensed CANDU reactors and began nuclear weapons tests shortly after they became operational in 1972. However, international observers have concluded that no plutonium was diverted from the safeguarded CANDU reactors (see ). The plutonium for the initial bombs came from the older CIRUS reactor built by Canada (see Nuclear Weapons above), but the material for India's most recent nuclear test, Operation Shakti, is thought to come from the locally-designed Dhruva reactor. India has also built a number of reactors, not under IAEA safeguards, that were derived from the CANDU design and are used for power generation. These may also be used for plutonium production.

Canada has volunteered to help destroy some of the leftover chemical weapons of the USSR. There is also talk of taking Soviet nuclear fuel and using it as fuel in CANDU reactors, but this is controversial
