Shifting leverage in U.S.-Canada relations challenges long-held assumptions ahead of USMCA review.
Tensions in the U.S.-Canada economic relationship have intensified in recent weeks, with U.S. officials adopting increasingly assertive public language toward their northern neighbour. Yet emerging analysis from trade economists and policy experts suggests that the underlying balance of leverage may be undergoing a quiet but significant transformation, one that could complicate Washington’s negotiating position as the scheduled review of the Canada–United States–Mexico Agreement (USMCA) draws nearer.
For decades the conventional view in Washington has been that the United States holds decisive economic superiority over Canada. The sheer size of the U.S. market, its role as the destination for roughly three-quarters of Canadian exports, and Canada’s geographic dependence on American infrastructure have underpinned that assumption. Recent U.S. statements — including repeated assertions that America “does not need Canada” and pointed criticisms of Canadian trade practices — appear to rest on that long-standing premise.
However, a growing body of assessment indicates that Canada has steadily built counter-leverage that may blunt the effectiveness of traditional pressure tactics. Under the leadership of Prime Minister Mark Carney, Ottawa has accelerated efforts to diversify trade relationships, expand critical-minerals partnerships beyond North America, and strengthen energy-export infrastructure aimed at European and Asian markets. These moves have reduced Canada’s relative vulnerability to any single trading partner while simultaneously raising the potential cost to the United States of prolonged tariff escalation.
Energy remains a central pillar of this shifting dynamic. Canada supplies approximately 60 percent of U.S. crude-oil imports and a substantial share of natural gas consumed in the Midwest and Northeast. The integrated pipeline and refining infrastructure that connects the two countries makes rapid substitution difficult and expensive in the short term. Recent Canadian investments in liquefied natural gas export terminals on the West Coast and expanded rail capacity have created credible alternative outlets, giving Ottawa greater flexibility in responding to U.S. demands or retaliatory measures.
Critical minerals constitute another area of emerging leverage. Canada is a major producer of nickel, cobalt, lithium and rare-earth elements essential to electric-vehicle batteries, renewable-energy technologies and defence applications. By forging new processing partnerships with European and Indo-Pacific allies, Canada has begun to position itself as a more independent player in global supply chains. This diversification reduces the risk that U.S. tariffs or export restrictions could cripple Canadian producers while simultaneously increasing costs for American manufacturers seeking secure, non-Chinese sources of these materials.
Trade-policy experts note that Carney’s background as a former central banker has informed a sophisticated approach to economic statecraft. Rather than engaging in direct confrontation, his government has focused on quietly expanding options — deepening ties with the European Union through enhanced regulatory alignment, pursuing new critical-minerals agreements in Asia, and reinforcing Canada’s role in stable energy supply to Europe amid ongoing global uncertainty. These steps have not severed the U.S. relationship — which remains Canada’s largest trading partner — but they have narrowed the asymmetry that once defined it.
Global economic conditions have further complicated the picture. Rising energy prices linked to Middle East developments have heightened the strategic value of reliable North American supply. At the same time, U.S. industries already grappling with higher input costs from earlier tariff rounds are voicing growing concern about additional disruptions. Business groups representing automotive, steel and chemical manufacturers have begun quietly lobbying Congress for de-escalation, warning that prolonged uncertainty could accelerate offshoring or erode competitiveness.
The approaching USMCA review, mandated six years after the agreement’s entry into force, provides a formal venue for renegotiation. U.S. negotiators have signalled interest in tightening rules of origin, addressing perceived dairy and poultry market access issues, and incorporating stronger labour and environmental provisions. Canadian officials have indicated willingness to discuss updates but have made clear that any concessions will be weighed against the broader costs of escalation. The review process, originally intended as a routine modernisation exercise, now carries the potential to become a high-stakes test of the new leverage realities.
Diplomatic sources in both capitals describe the current atmosphere as one of “managed friction.” Private discussions continue even as public rhetoric sharpens. Canadian representatives have emphasised that Ottawa remains committed to the long-term health of the bilateral relationship and that diversification efforts are defensive rather than hostile. U.S. officials continue to stress the need for reciprocal fairness while acknowledging the deep integration of continental supply chains.
Market participants have registered the shifting tone through modest movements in currency and commodity prices. The Canadian dollar has shown resilience, and spreads between Canadian and U.S. energy benchmarks have remained relatively stable, suggesting investors do not yet anticipate a full breakdown in commercial ties.
The broader lesson emerging from the current standoff is that economic interdependence, once viewed primarily as a source of U.S. leverage, can also constrain unilateral action. When two economies are as tightly linked as those of the United States and Canada, the costs of disruption tend to be mutual and difficult to contain. Carney’s strategy appears to rest on the recognition that a more balanced interdependence may ultimately produce more stable and predictable outcomes than repeated cycles of threat and retaliation.
As formal USMCA review talks begin in earnest, both sides will face the challenge of reconciling domestic political pressures with the practical realities of continental commerce. The outcome will help determine whether North American economic integration evolves toward greater resilience or risks further fragmentation in an already uncertain global environment.
For now, the assumption of overwhelming U.S. dominance appears less certain than in previous decades. Canada’s quiet accumulation of alternative options has altered the negotiating math, forcing Washington to confront a more complex leverage landscape than many had anticipated.
Nearly 150,000 California Mail Ballots Rejected In Primary
California election officials are examining why nearly 150,000 mail-in ballots were rejected during the state’s June primary, with late-arriving ballots accounting for most of the increase.
The higher rejection rate comes despite years of election law changes designed to make voting more accessible and ensure more ballots are ultimately counted.
According to data compiled by the California Secretary of State’s office, 148,241 mail-in ballots were rejected during the June primary, representing 1.73% of all mail ballots returned.
That marks an increase from the 2024 primary, when 108,982 ballots were rejected, or 1.56% of all mail ballots cast.
The largest reason for rejection was ballots arriving too late to qualify under California law.
State data shows that 93,479 ballots were rejected because they failed to meet the state’s deadline requirements.
California allows mail ballots to arrive up to seven days after Election Day, provided they are postmarked on or before Election Day.
Voting experts believe many of the rejected ballots received postmarks dated after Election Day, making them ineligible to be counted even if they arrived within the seven-day grace period.
Kim Alexander, president of the nonpartisan California Voter Foundation, said the timing of postal processing appears to be a significant concern.
“Ballots rejected due to lateness are caused primarily to being postmarked too late to count, not because they arrived too late to count,” Alexander said.
Election experts have questioned whether recent operational changes within the U.S. Postal Service may be contributing to delayed postmarks.
Earlier this year, a group of mostly Democratic U.S. senators wrote to the Postal Service expressing concern that mail-processing changes could affect ballot handling during federal elections.
Updated Postal Service procedures mean postmarks may reflect when mail is processed at regional facilities rather than when it first enters the mail system.
Because processing centers have been consolidated in some areas, election officials have warned that postmark timing could be affected.
Before the June primary, California election officials encouraged voters to mail ballots as early as possible because of potential postal delays.
The June election also featured a highly competitive race for governor, which some experts believe encouraged many voters to wait until the final days before casting ballots.
In addition to late-arriving ballots, approximately 44,000 ballots were rejected because election officials determined the voter’s signature did not match the signature on file.
Another 8,300 ballots were rejected because the return envelope did not contain a signature.
State records also show that 743 ballots were rejected because those voters had already cast another ballot.
Other rejected ballots involved missing ballots inside return envelopes or multiple ballots submitted in a single envelope.
The highest rejection rate in the state occurred in Tulare County, where 3.52% of returned mail ballots were rejected.
Alpine County and Merced County followed closely, each recording rejection rates of 3.36%.
California has frequently faced criticism for taking weeks to complete vote counting after major elections, largely because state law permits ballots meeting certain requirements to continue arriving after Election Day.
Following the June primary, President Donald Trump again criticized California’s election system, while the Department of Justice opened an investigation into election administration in Los Angeles County.
Election experts emphasize that the increase in rejected ballots should not be interpreted as evidence of widespread voter fraud.
A 2025 report by the Brookings Institution found documented cases of mail ballot fraud remained extremely rare, estimating roughly four cases for every 10 million mail ballots cast, The Associated Press reported.
State officials have not identified evidence of widespread fraud connected to the June primary, but the increase in rejected ballots is expected to receive additional scrutiny as election administrators evaluate whether changes in postal operations, voter behavior or election procedures contributed to the higher rejection rate.
