Canadian Prime Minister Mark Carney is seeking to expand trade ties with Britain as a deepening tariff dispute with the United States pushes Ottawa toward new allies.
Sources familiar with the situation told The Mail on Sunday that the government in Ottawa is warming to a proposed CANZUK alliance alongside Australia, New Zealand, and the United Kingdom. The shift follows an abrupt collapse in trade negotiations with Washington last week that sparked a new round of tit-for-tat tariffs across the North American border.
"I think if you asked anyone in the government, they would all say they are very supportive of this CANZUK idea," one source said. The source added that London and Ottawa now share a "historic opportunity" to bolster bilateral trade, noting that both countries have become "estranged" from their traditional economic partners, the United States and the European Union respectively.

Canadian diplomatic sources acknowledged that a recent change of Prime Minister and a cabinet reshuffle in London had rendered initial trade discussions "difficult". However, Canadian officials expressed optimism about establishing a fresh working relationship with the new administration in Westminster.
"Burnham's government is relatively new and finding its feet, but in preliminary discussions we're sensing a real openness and desire to move on that," a Canadian diplomatic source said.
Collapse of North American trade talks
Britain currently stands as Canada's third-largest trading partner, but efforts to deepen bilateral cooperation have taken on fresh urgency following new protectionist measures from Washington. Last week, US President Donald Trump announced that the United States would slap tariffs on Canadian vehicles and automotive parts starting at the beginning of next year, accusing Canada of "ripping off" America.
Ottawa replied swiftly to the American tariffs by announcing retaliatory levies on £15billion worth of US imports, marking a sharp escalation in trade friction between the two neighboring economies.
The cross-border automotive industry represents one of the most tightly integrated manufacturing sectors in North America, with vehicles and components routinely crossing the United States and Canadian border multiple times during assembly. New trade barriers threaten to disrupt supply chains that have underpinned North American industrial production for decades.
The vision for a CANZUK alliance
The CANZUK proposal advocates for formal trade, diplomatic, and security cooperation among four Commonwealth nations: Canada, Australia, New Zealand, and the United Kingdom. Proponents view the alliance as a means to create a powerful trading bloc capable of acting as an economic counterweight to the market dominance of the United States, China, and the European Union.
Prime Minister Mark Carney brings extensive international finance experience to the trade talks. Before assuming political leadership in Ottawa, Carney served as Governor of the Bank of Canada from 2008 to 2013 and subsequently as Governor of the Bank of England from 2013 to 2020, giving him deep familiarity with both the British and Canadian financial systems.
For Britain, expanding trade with Canada aligns with post-Brexit economic strategy. Since departing the European Union, the single market bloc of European nations, the United Kingdom has actively sought to negotiate new bilateral commerce agreements and deepen trade ties with non-EU allies across the globe.
Political backing and future prospects
The recent trade dispute between Ottawa and Washington has bolstered political momentum for the CANZUK initiative across party lines in both countries. In March, UK Conservative Party leader Kemi Badenoch and Canadian Conservative Party leader Pierre Poilievre both publicly endorsed the proposal to create closer economic bonds between the nations.
With trade talks between Canada and the United States stalled, preliminary discussions between Canadian and British representatives are expected to continue as both governments assess formal steps toward expanding bilateral commerce.
