Canada has formally proposed a 16-year renewal of the North American Free Trade Agreement, a move designed to insulate the continent’s economic architecture from political cycles. The request, presented during ongoing trilateral talks in Washington, signals Ottawa’s intent to secure long-term market access amid rising protectionist sentiment in the United States and Mexico’s shifting trade posture.
UK trade negotiators, who have maintained observer status since Brexit, are closely monitoring the developments. British officials see the NAFTA renegotiation as a bellwether for global trade governance. A prolonged renewal would reduce instability in Canada’s economy, a key G7 partner with which the UK is pursuing a bilateral trade agreement.
The proposal, confirmed by Canadian sources, would extend the current agreement through 2040, conditional on modernised provisions for digital trade, labour standards and environmental commitments. Canada’s chief negotiator described the timeline as “ambitious but necessary for business certainty.” The US trade representative has yet to respond formally, but internal documents suggest reluctance to commit to a 16-year period without significant concessions on dairy market access and automotive rules of origin.
Mexico’s delegation is pressing for a shorter review cycle, citing the need to adapt to evolving supply chains and potential US policy shifts after the 2028 presidential election. Analysts note that Mexican negotiators are wary of locking in terms that could disadvantage the country if US trade policy becomes more restrictive.
The UK’s interest is not merely academic. Officials in London view a stable North American trading bloc as essential for mitigating supply chain disruptions that could affect UK-based multinationals. A senior Treasury source, speaking on condition of anonymity, confirmed that the UK’s trade team is “paying close attention to the rules of origin negotiations, as they will set precedents for future UK deals with each country.”
Negotiations are expected to intensify before the current NAFTA agreement expires in July next year. If a 16-year renewal is granted, it would be the longest fixed-term trade agreement in recent history, surpassing the 12-year pact signed between the EU and Japan in 2019. Critics argue that such a long horizon risks embedding outdated provisions, but supporters counter that it would curb the volatility inflicted by unilateral tariff actions in recent years.
For the UK, the outcome will shape its own trade strategy. A successful Canadian push for longevity would reinforce London’s approach of seeking durable agreements with like-minded economies, rather than pursuing rapid but shallow trade pacts. The UK trade secretary is expected to visit Ottawa in the coming weeks to discuss bilateral progress and to gauge the Canadian position on a UK-Canada trade deal that could run parallel to NAFTA.
The Canadian proposal has not been made public, but sources familiar with the talks confirm that Ottawa is willing to compromise on dispute resolution mechanisms and digital services taxes in exchange for the extended timeline. The US appetite for such a deal remains uncertain, particularly given the political capital required to secure congressional approval for a 16-year commitment.
As the negotiations continue, the UK’s role as a silent stakeholder will persist. Whitehall sources indicate that the UK is preparing contingency plans should the talks collapse, including accelerated bilateral talks with Canada and Mexico. However, officials stress that a stable NAFTA remains the preferred outcome.
The next round of official talks is scheduled for early May, with a ministerial-level meeting expected in June. The clock is ticking on one of the world’s largest trade blocs, and the Canadian proposal has introduced a new element of strategic ambition into the process.
