Canada Weighs Involvement in US Defense System Despite Campaign Promise to Deter Washington’s Influence

Canadian officials are weighing the advantages and costs of participating in a missile defense system with the United States, despite the Canadian Prime Minister's election campaign promise to reduce Washington's influence. Mark Carney, the Prime Minister, explained that Canada will only co-operate with the US when it is in Canada's best interest, adding that the country must be proactive in defense against incoming missiles with a 30-second warning time before impact. Ottawa currently faces missile threats from Russia and China, including hypersonic missiles that can change course in flight. The joint Canada-US North American Aerospace Defence Command (NORAD) is upgrading its radar system to detect incoming threats. However, critics warn that participation in the new Golden Dome defense system could jeopardize the NORAD alliance if Canada doesn't agree to purchase F-35 fighter jets from the US. The country has committed over $38-billion to upgrade NORAD's ability to detect missile threats.
