The Canada-U.S.-Mexico Agreement could collapse within the next month if the United States decides to walk away from the trade pact [1].
A breakdown of the trilateral agreement would disrupt the established trade corridor between the three nations and create significant economic uncertainty for North American markets.
Brian Lilley, a political columnist for the Toronto Sun, said the agreement faces a critical risk of "blowing up" [1]. According to Lilley, the United States may choose to exit the deal because it views Canada as being unserious during trade negotiations [1].
The timeframe for a possible collapse is approximately one month [2]. This puts a critical deadline on the current negotiations for July 1, 2026 [2].
Lilley said the risk stems from the perception of Canadian engagement in the review process. If the U.S. determines that the negotiations are not progressing in a manner that meets its interests, the columnist said the U.S. could simply walk away [1].
Such a move would leave the three countries without the overarching legal framework that governs their mutual trade. The review negotiations are intended to determine the future of the pact, but the current tension suggests a precarious path toward that goal [1].
The potential for a sudden exit by the U.S. creates a high-pressure environment for Canadian negotiators as they approach the July 1 deadline [2].

The potential collapse of CUSMA represents a systemic risk to North American supply chains. Because the agreement provides the legal certainty required for cross-border investment, a U.S. withdrawal would likely trigger immediate volatility in currency markets and trade disruptions for sectors heavily reliant on integrated manufacturing, such as the automotive industry.
