Cusma and the next trade test as summer talks approach

Cusma is entering a more fragile phase as Ottawa and Washington move toward a scheduled review that could stretch well beyond the summer. Prime Minister Mark Carney is drawing a clear line against the idea that the United States is setting the terms, while U. S. officials are signaling that trade irritants remain central to what happens next.

What happens when both sides arrive with lists?

The current moment matters because the two governments are no longer speaking in broad generalities. Carney has said the United States does not dictate the terms, and his government says it has already made counter-proposals. At the same time, U. S. officials are pointing to a set of problems that they want addressed before talks fully advance.

Those issues include dairy, provincial bans on American liquor, the Online Streaming Act, the Online News Act, and procurement rules in Ontario, Quebec and British Columbia that effectively exclude bids from U. S. firms. The U. S. side has also flagged Canada’s plastic-waste agenda and dairy policy as sticking points.

The schedule itself adds pressure. The agreement is headed for a review that includes a decision on whether to extend it beyond 2036, while Ottawa is still trying to address tariffs on steel, aluminum and autos. That means the next phase is not just about one file, but about whether the broader trading framework can keep absorbing political strain.

What if the talks begin only after preconditions are met?

The clearest signal from the U. S. side is that it wants concessions before real negotiations begin. One source familiar with the discussions described the approach as a demand for upfront changes, rather than a normal opening position. Another source said Washington appears content to keep collecting tariff revenue while seeing what else it can extract from Canada.

Carney has resisted that framing. He says Canada has counter-proposals and is prepared to work through the issues in a broader negotiation. His public message is that this is a negotiation, not a one-sided dictate.

Howard Lutnick, the U. S. Commerce Secretary, has sharpened the tone. He called Canada’s refusal to put U. S. spirits on shelves “insulting and disrespectful to America, ” and said Canada benefits from what he called the best tariff deal in the world. He also framed the dispute as a question of domestic production, arguing that companies should make products at home if they want to avoid tariffs.

What happens when the political tone hardens?

The tone matters because it shapes how much room negotiators have. Carney has faced repeated pressure not to offer more concessions, and the U. S. side has paired criticism with a broader list of policy complaints. That combination makes it harder for either government to claim flexibility without appearing weak at home.

Canada has also already made moves in earlier disputes, including lifting the digital sales tax in 2025 and imposing tariffs on Chinese electric vehicles in 2024 at the request of the previous U. S. administration. The fact that those concessions are now part of the backdrop strengthens Ottawa’s argument that it has already given ground.

Janice Charette, Canada’s chief trade negotiator to the United States, has warned that the road ahead will be bumpy and that talks may extend beyond the scheduled July 1 review date. That is a useful signal for readers: the real risk is not a single breakdown, but a long period of uncertainty.

Who gains, and who is exposed, if Cusma stays under pressure?

The biggest winners in the short term are negotiators on both sides who can frame themselves as defending national interests. Carney gains political space by rejecting the idea of unilateral concessions. U. S. officials gain leverage by keeping the list of irritants in play.

The biggest losers are industries and businesses that need clarity. Canadian exporters facing U. S. tariffs on steel, aluminum and autos remain exposed. Firms that depend on cross-border procurement also face uncertainty if the current dispute spills into contract decisions. For consumers, the risk is not only higher costs, but also a slower-moving trade environment that leaves investment decisions in limbo.

For now, the safest reading is cautious: Cusma is not collapsing, but it is being tested by a harder bargaining style, a longer timetable, and a political atmosphere that rewards toughness over compromise. The key is to watch whether the two sides move from public signaling to practical concessions, or whether the review period becomes a holding pattern that lasts well past July 1 ET. In that sense, cusma is less a settled trade framework than a live stress test of what both governments are willing to trade away, and what they are not.
