Alliances don’t usually break overnight; they thin out over time. In 2026, the U.S.-Canada relationship looks less steady than it used to. Under Prime Minister Mark Carney, Canada has taken several steps that have unsettled Washington. For example, Carney publicly criticized U.S. military strikes on Iran, and he moved ahead with a quiet trade reset with China even after direct warnings from former President Donald Trump.
At the same time, Canada’s defense problems remain hard to ignore. The country depends heavily on U.S. support for North American security. Add reports that former Iranian regime officials have found shelter in Canada, and the trust gap grows wider. The result is a simple concern in U.S. policy circles: Canada still talks like an ally, but its choices don’t always line up that way.
This analysis reviews the main points driving the U.S.-Canada strain in 2026, using public statements, reported policy decisions, and reactions from political figures. With tensions rising worldwide, these disputes could shape North American security for years.
Carney’s Rebuke: Calling the U.S. Out on Iran Strikes
Carney has spoken bluntly about U.S. actions in the Middle East. In early March 2026, at a press conference in Sydney, Australia, he said the U.S.-Israeli strikes on Iran were “inconsistent with international law.” He also said the situation showed a “failure of the international order.” At the same time, he repeated that Canada supports stopping Iran from getting nuclear weapons.
That message shifted quickly from his earlier stance. Only days before, Carney had backed the U.S. operation “with regret,” while describing Iran as the “principal source of instability and terror throughout the Middle East.”
Carney also stressed what Canada did not get from the U.S. He said Canada was “not informed in advance” and “not asked to participate.” Reports tied the strikes to the killing of Iran’s Supreme Leader Ayatollah Ali Khamenei and to attacks on nuclear sites. Even so, Carney urged the U.S. and Israel to “respect the rules of international engagement” and pushed for “rapid de-escalation.”
In a joint statement with Foreign Affairs Minister Anita Anand, Carney kept Canada’s bottom line clear: “Iran must never be allowed to obtain or develop nuclear weapons.” However, he framed decades of failed diplomacy as part of the problem.
Some U.S. observers read this as more than a policy disagreement. They see it as a public scolding at a moment when Washington expected support. Carney’s language also matched themes from his speech to Australia’s Parliament, where he warned that the “U.S.-led global order is shifting.” Critics say that posture makes Canada look less dependable when conflict rises.
- Key Carney quotes on the Iran strikes:
- “We were not informed in advance, we were not asked to participate.”
- “The current conflict is another example of the failure of the international order.”
- “Canada supports the United States acting to prevent Iran from obtaining a nuclear weapon.”
- “We implore all parties… to respect the rules of international engagement.”
To many in Washington, the message landed poorly. One U.S. analyst summed it up this way: Canada under Carney looks more willing to lecture the U.S. than stand beside it.
Harboring Enemies: Former Iranian Officials Staying in Canada After the IRGC Listing
Tensions grew sharper because of Canada’s record on Iranian regime-linked figures. Even after Canada listed the Islamic Revolutionary Guard Corps (IRGC) as a terrorist organization in 2024, reports from 2024 and 2025 said hundreds of people tied to the IRGC still lived in Canada. Deportations have appeared limited, even with investigations underway.
Canada’s Immigration and Refugee Protection Act bars senior Iranian officials who served since 2003. It also blocks IRGC members. Still, critics say enforcement has moved slowly. In 2024, five regime figures reportedly faced deportation proceedings. Conservative MP Melissa Lantsman criticized the government for allowing what she called “sanctuary for terrorists.” While Carney’s government has pointed to added steps meant to hold the regime accountable, public results have looked thin. Only one confirmed public removal has been reported alongside dozens of probes.
For U.S. policymakers, this undercuts efforts to isolate Iran, especially after the strikes. If Canada wants to present a united front, critics ask why it continues to host people linked to a regime the U.S. treats as a top threat. Some analysts connect the issue to domestic politics, including claims that Liberal leaders worry about backlash from voters sympathetic to Iran.
- Timeline of the IRGC designation and fallout:
- June 2024: Canada lists the IRGC as a terrorist entity.
- November 2022: Canada expands bans on senior officials.
- 2025: Reports describe about 700 IRGC-linked residents, along with calls for broad deportations.
- December 2025: Iran responds by labeling Canada’s navy “terrorist.”
Even without a major policy break, the optics matter. The ongoing presence of Iranian officials in Canada feeds U.S. doubts and may also encourage Iranian proxies.
Quiet Deals With Beijing: Carney’s China Shift Despite Trump’s Warnings
In January 2026, Carney visited China and came back with a preliminary trade agreement. Reports said the deal reduced tariffs on Canadian canola and opened the door for up to 49,000 Chinese electric vehicles (EVs) to enter Canada at a 6.1% rate. The arrangement was described as a “strategic partnership” built around energy, agri-food, and trade. Carney called it a “reset” and said it could unlock $3 billion in exports.
That move came with a clear political cost. President Donald Trump warned Canada not to proceed. In January 2026, Trump threatened 100% tariffs on Canadian goods if the agreement went forward. He also said Canada could become a “drop-off port” for Chinese products trying to dodge U.S. duties. His warning went further: “China will eat Canada alive, completely devour it.” On Truth Social, Trump repeatedly referred to Carney as “Governor,” tied to earlier annexation talk.
Carney still moved ahead and presented the deal as a practical diversification. He also framed it against a broader shift in the “U.S.-led global order.” Yet that approach clashes with U.S. policy, since Washington has kept heavy pressure on Beijing through tariffs and other restrictions. In addition, the reported openness to Chinese investment in EV manufacturing raised security concerns among critics.
- Reported details of the Canada-China deal:
- China will lower canola tariffs to 15% by March 2026.
- China exempts Canadian canola meal, lobsters, crabs, and peas from anti-discrimination tariffs through the end of 2026.
- Canada allows 49,000 Chinese EVs at a 6.1% tariff, with a possible increase to 70,000.
- The agreement lists five pillars: trade and investment, multilateral cooperation, finance, public safety, and people-to-people ties.
To U.S. critics, the timing was the point. Canada chose economic upside with Beijing, while friction with Washington was already high.
Weak Without U.S. Support: Canada’s Military Readiness Problems
Canada’s military struggles make this diplomatic drift riskier. In 2026, internal reporting described a force with limited readiness for a NATO crisis. One assessment said only 58% of forces were ready, and nearly half ofthe equipment was “unavailable and unserviceable.”
In the air, the Royal Canadian Air Force continues to rely on older CF-18 Hornets. F-35 replacements have been delayed. First deliveries were expected in 2026, while full capability was projected for 2028 to 2032. Meanwhile, some aircraft were described as grounded or outdated.
The Navy faces a similar strain. Victoria-class submarines have a long record of issues and are nearing retirement. Canada has looked at German or South Korean firms for replacements. On top of that, ships have spent long stretches in refit, and staffing has remained a challenge.
On land, Canada fields tanks and armored vehicles, but readiness still draws complaints. Numbers on paper do not always translate into usable capacity.
Carney’s government has promised upgrades, including 88 F-35s, MQ-9B drones by 2028, and new multi-role aircraft. Still, spending remains below NATO’s 2% of GDP target. At the same time, tariff threats and political tension with the U.S. could complicate defense cooperation.
- Canada’s military inventory highlights (2026):
- Air: 351 aircraft, 66 fighters (mostly older), 145 helicopters.
- Navy: 73 vessels, including 12 submarines, described as in poor condition.
- Army: 74 tanks, more than 21,700 armored vehicles, with ongoing readiness issues.
- Personnel: about 68,000 active-duty members.
- Plans: F-35s (2026 and beyond), RPAS drones (2028), Victoria modernization (mid-2030s).
Because NORAD depends on tight coordination, Canada’s weaknesses affect the U.S. too. That makes political distancing feel even more reckless to American observers.
Liberal Politics at Home: Claims of Playing to the Muslim Vote
Critics also point to domestic politics, especially Canada’s Muslim electorate. Some argue the Liberal Party’s approach to Iran reflects a desire to avoid alienating Muslim voters. In 2026 polling referenced by critics, Muslim Canadians showed higher opposition to U.S. strikes, and about three in ten reportedly believed the war improved life for Iranians.
The political tension has shown inside the party. Liberal MP Will Greaves broke ranks and criticized Carney’s support for the strikes, saying it backed “unilateral and illegal use of military force.” Other former ministers have voiced similar concerns.
Opponents say the same vote math explains slow enforcement against IRGC-linked residents. In that view, the government delays action to limit community backlash. Supporters of Carney’s approach call it “principled pragmatism.” Critics hear election strategy.
- Claims cited as signs of pandering:
- Liberal MPs are engaging with anti-strike posts online.
- Slow movement on IRGC-linked cases amid community pushback.
- Carney’s careful, regret-based language on the strikes was aimed at balancing alliance ties and domestic pressure.
Whether those accusations are fair or not, they shape perception in Washington. U.S. officials care less about Canadian politics and more about results.
Carney’s decisions, from public criticism over Iran to trade outreach to China, have built a picture of a Canada less tied to U.S. priorities. With tariff threats hovering and Canada’s defense dependence still high, American leaders may rethink what they expect from their northern partner. Carney keeps saying the global order is shifting, and the U.S. now has to decide how much risk it can accept from an ally shifting with it.
