The United States is expected to decline an extension of the United States-Mexico-Canada Agreement (USMCA), triggering a decade-long countdown toward the trade pact’s potential expiration, according to reports from Reuters. This decision effectively initiates a review process and a sunset clause that will determine the long-term viability of the free-trade framework governing North American commerce.
The USMCA contains a “sunset clause” requiring the three member nations to confirm their commitment to the deal. Because the U.S. is not expected to seek an extension, the agreement will move toward a scheduled review phase unless the parties agree otherwise.
This development follows a period of shifting rhetoric from the U.S. administration. Politico reports that Donald Trump has since expressed dissatisfaction with the deal. This shift creates a complex political environment for Canada and Mexico, who rely heavily on the pact’s stability for automotive and agricultural exports.
Why is the USMCA facing a countdown to expiration?
The USMCA is subject to a specific legal mechanism known as the joint review. According to the terms of the USMCA agreement, the three countries must meet to review the pact. If the members do not agree to extend the agreement’s life during this review, the pact remains in force for an additional 10 years before it expires completely.

By not seeking an immediate extension to the agreement’s lifespan, the U.S. effectively starts a clock. According to Reuters, this means the agreement will now operate under a defined timeline, creating a decade-long window of uncertainty for businesses and governments across North America.
Industry analysts suggest this move provides the U.S. with significant leverage. By allowing the countdown to proceed, the U.S. can pressure Canada and Mexico to make concessions on specific issues—such as dairy market access or automotive rules of origin—before the final expiration date arrives.
How will this impact Canada and Mexico?
For Canada and Mexico, the lack of a permanent extension introduces “regime uncertainty,” a term used by economists to describe the risk businesses face when trade rules are subject to change. The CBC reports that for Canada, the July 1 anniversary of the CUSMA (Canada’s name for the deal) highlights the fragility of these trade relations, particularly regarding disputes over energy and dairy.

Mexico faces similar pressures. The U.S. has previously raised concerns regarding Mexico’s energy policies and its trade relationship with China. According to the South China Morning Post, the U.S. may use the looming expiration of the trade pact as a tool to force Mexico to limit Chinese investment in its manufacturing sector, particularly in the automotive industry.
The automotive sector is the most vulnerable. The USMCA mandates that a high percentage of a vehicle’s components must be made in North America to qualify for zero tariffs. If the pact expires or is fundamentally altered, the cost of producing and shipping cars across the three borders would increase significantly, potentially disrupting global supply chains.
What happens if the U.S. exits or the pact expires?
If the USMCA expires without a renewal, the region would lose the comprehensive tariff-free framework. While the U.S. could theoretically negotiate separate bilateral deals with Canada and Mexico, the loss of a trilateral agreement would complicate the “rules of origin” that allow parts to move seamlessly between all three countries.
The BBC notes that the looming deadline creates a high-stakes environment for the review. If the U.S. maintains its current stance, the meeting will not be a formality but a negotiation for the survival of the pact. Failure to reach an agreement would lead to a gradual wind-down of the treaty’s benefits over the subsequent decade.
The current tension reflects a broader U.S. shift toward protectionism and a desire to “nearshore” production to reduce reliance on Asian markets.
Timeline of the USMCA Sunset Clause
| Key Date/Event | Action/Status | Impact |
|---|---|---|
| – | USMCA Entry into Force | Established new labor and digital trade rules. |
| – | Joint Review | Members must decide whether to extend the pact’s life. |
| Post-Review | 10-Year Countdown | If not extended, the pact enters its final decade of validity. |
| – | Potential Expiration | The agreement ceases to exist unless a new deal is signed. |
What is next for North American trade?
The immediate focus now shifts to the joint review. Market participants and government officials in Ottawa and Mexico City are expected to spend the intervening period attempting to resolve outstanding disputes to ensure the U.S. is inclined to extend the agreement during that window.

The U.S. Trade Representative (USTR) will be the primary office managing these tensions. Any official announcement regarding a change in the U.S. position or a formal request for renegotiation will likely emerge from the USTR or the White House.
The next confirmed checkpoint is the formal review process, where the three nations will officially meet to determine the future of the agreement. Until then, the trade pact remains in effect, but with a defined expiration date that may influence investment and manufacturing decisions across the continent.
