US President Donald Trump has escalated criticism of Canada over its reported opposition to his proposed ‘Golden Dome’ missile defence system, warning that Beijing’s growing influence could threaten Canadian security. The remarks came after Trump’s address at the World Economic Forum in Davos, where he outlined plans for a large-scale missile shield stretching from the United States to Greenland.
In a post on his social media platform Truth Social, Trump claimed Canada had opposed the Golden Dome proposal despite its potential defensive benefits. He alleged that Ottawa was instead prioritising business ties with China, a move he warned could have serious strategic consequences. Trump stated that China could dominate Canada economically and politically within a short span if current policies continue.
The Golden Dome, as described by Trump, is an advanced missile defence system designed to intercept incoming threats, including missiles launched from space. According to the former US President, the system would significantly enhance North American security by providing early detection and interception capabilities across a wide geographic area. Greenland’s strategic location in the Arctic makes it a key component of the proposed defence network.
Trump argued that while the system would primarily safeguard US territory, it would also offer protection to neighbouring countries, including Canada. He expressed frustration that Canada was not fully aligned with the initiative, suggesting that collective security should outweigh political or economic disagreements.
Canada, however, has not publicly confirmed voting against the proposal in any formal international forum. Canadian officials have historically taken a cautious approach to missile defence participation, balancing national security interests with diplomatic considerations and public opinion. Ottawa has also maintained that engagement with China is driven by trade and economic priorities, even as concerns over Beijing’s geopolitical ambitions continue to grow.
The comments have renewed debate over Canada’s role in continental defence and its evolving relationship with both Washington and Beijing. Analysts note that US concerns about China’s expanding influence are increasingly shaping its foreign and defence policies, particularly in strategically sensitive regions such as the Arctic.
China has steadily increased its presence in Arctic research, trade routes, and infrastructure investments, prompting scrutiny from Western nations. While Canada has acknowledged the need to monitor these developments, it has also stressed the importance of maintaining stable economic ties.
Trump’s remarks reflect broader tensions within the global security landscape, where defence initiatives are often intertwined with trade, diplomacy, and geopolitical rivalry. The proposed Golden Dome system has not yet moved beyond the conceptual stage, and its technical feasibility, cost, and international participation remain open questions.
As discussions continue, experts believe any missile defence arrangement involving multiple countries would require extensive consultation and formal agreements. For now, Trump’s statements have drawn attention to differing approaches within North America on defence cooperation and how best to respond to China’s growing global footprint.
