Ottawa sits at the heart of Canada's response to a fresh wave of trade uncertainty, after the United States Ambassador to Canada delivered a pointed message this week: Canada needs to make the case for why the Canada-United States-Mexico Agreement (CUSMA) still matters — and make it convincingly.
Trump Questions the Future of CUSMA
President Donald Trump has once again raised questions about the longevity of the landmark trade deal, which governs the bulk of commerce between the three North American partners. The remarks, which came as part of a broader pattern of skepticism from the White House toward multilateral trade commitments, sent ripples through Ottawa's political and business communities.
The US Ambassador's message was blunt: Canada should be actively selling the value of the agreement rather than assuming its survival. The phrasing — "put on a sales hat" — underscored just how much the diplomatic ground has shifted since CUSMA's predecessors were first negotiated.
What's at Stake for Canada
Canada sends roughly 75 per cent of its exports to the United States. Any disruption to CUSMA would have sweeping consequences — from the auto manufacturing sector in Ontario, to agriculture on the Prairies, to the tech corridors of Kanata. The deal has underpinned decades of integrated supply chains that would be enormously costly to untangle.
For Ottawa specifically, the uncertainty lands close to home. The federal public service, which employs hundreds of thousands of Canadians in the National Capital Region, includes the very trade negotiators, economists, and diplomats who built and continue to defend CUSMA. Ministers and senior officials at Global Affairs Canada and the Department of Finance have been closely monitoring the US posture.
Canada's Diplomatic Response
So far, Canadian officials have struck a measured tone — reaffirming the mutual economic benefits of the agreement while leaving room for negotiation. The government has reportedly been engaging US lawmakers, business groups, and state governors in a quiet but systematic effort to build support for CUSMA's continuation south of the border.
That approach aligns with the Ambassador's "sales" framing: rather than waiting for formal renegotiation talks, Canada is making the economic case directly to American stakeholders who benefit from open trade with their northern neighbour.
A Familiar Playbook
This isn't the first time Canada has faced this kind of pressure. The original NAFTA renegotiation under Trump's first term was a bruising, years-long process that tested Ottawa's diplomatic bandwidth. Canadian negotiators ultimately secured a deal widely viewed as a reasonable outcome, but only after significant concessions and months of uncertainty that rattled businesses on both sides of the border.
Many Ottawa trade watchers are drawing on those lessons now, noting that Canada's best leverage has always been the mutual dependence embedded in cross-border trade — and that making that case clearly and loudly is exactly what the Ambassador is advising.
What Comes Next
USMCA/CUSMA is formally up for review in 2026, giving both sides an opportunity to renegotiate terms. Whether that review becomes a flashpoint or a manageable process will depend in large part on the tone set in Washington — and on how effectively Canada can build and sustain its case.
For now, Ottawa's diplomatic and trade machinery is on high alert, ready to engage whatever comes next.
