DOJ Halts Antitrust Cooperation With Canada Amid Trade War Escalation
A technical agency suddenly pausing work with an ally signals how broken the relationship has become.
Mark
So the DOJ just stopped talking to Canada's antitrust people entirely? That seems like a pretty big deal.
Mimi
That's what the emails suggest. Lynda Marshall sent a directive to halt all cooperation on cases and policy work with Canadian authorities. No reason given.
Luke
But the DOJ denied it happened. They said they only delayed one meeting. So we have conflicting accounts from the same institution.
Mimi
Right. The Wall Street Journal has the emails, which is pretty concrete. But the DOJ's statement is also on the record. It's possible both things are true in some way—maybe the order was given but characterized differently internally.
Mark
Why would they do this now, though? What's the connection to the trade war?
Mimi
The timing is the thing. This happens as Trump's tariffs on Canadian goods are in effect, and Canada is about to hit back with retaliatory tariffs. The antitrust division doesn't usually get caught up in trade disputes.
Luke
That's the real story, isn't it? Not whether the order was given, but what it means that a technical, apolitical agency is suddenly pausing work with an ally. That's how you know the relationship is broken.
Mark
Do we know if this freeze is permanent or just until things cool down?
Mimi
The source material doesn't say. The DOJ framed it as temporary—a delay on one meeting. But if the emails are accurate, it sounds broader than that.
Luke
And that's where we have to be honest with readers: we don't know the actual scope. We know there's a dispute about what happened, and we know the context is a serious trade conflict.
Mark
So what happens next?
Mimi
Canada starts its retaliatory tariffs on September 8. Whether that changes anything about the antitrust freeze, we'll have to see.

- Emails obtained by the Wall Street Journal show a senior DOJ official ordered staff to halt all antitrust work with Canada — with no explanation given.
- The DOJ fired back, insisting no such sweeping directive was issued and framing the situation as a routine meeting postponement, leaving the true scope of the freeze in dispute.
- The suspension lands inside a broader collapse of U.S.-Canada relations, marked by a 50% tariff on $20 billion in Canadian goods and Trump's executive order renaming Lake Ontario to 'Lake America.'
- Canada is not standing still — Prime Minister Mark Carney has announced dollar-for-dollar retaliatory tariffs on $20 billion in American goods, set to begin September 8.
- The deeper question now is whether this freeze on antitrust cooperation is a tactical escalation, a bureaucratic hedge, or the first sign of a more permanent fracture in how two longtime partners govern together.
What was once a quiet corridor of legal cooperation between two neighboring nations has become another casualty of an escalating trade conflict. The U.S. Justice Department's antitrust division was directed this week to suspend all coordination with Canadian authorities, a move that — whatever its precise scope — reveals how deeply political tensions can reach into the technical machinery of governance. As tariffs mount and symbolic gestures like renaming Lake Ontario harden the atmosphere, the United States and Canada find themselves renegotiating not just trade terms, but the very texture of their institutional trust.
The Justice Department's antitrust division was ordered this week to suspend all cooperation with Canada, according to emails obtained by The Wall Street Journal. Lynda Marshall, head of the division's international section, directed staff on Wednesday to halt work on both cases and policy matters with Canadian authorities — offering no explanation. By Friday, section chiefs were asked to inventory every area of bilateral collaboration, with results due by end of day.
The DOJ disputed the characterization. A department statement denied that any such sweeping directive had been issued, describing the situation instead as a decision to postpone a single scheduled meeting so staff could prepare more thoroughly. The gap between what the emails showed and what the department claimed left the actual reach of the freeze unresolved.
The antitrust pause does not exist in isolation. Since President Trump returned to office in January 2025, the U.S.-Canada relationship has deteriorated sharply. His administration imposed a 50 percent tariff on roughly $20 billion in Canadian goods last month, and Trump signed an executive order renaming Lake Ontario to 'Lake America' within federal usage — a symbolic gesture that, while non-binding on Canada or U.S. states, sharpened the tone between the two neighbors.
Canada's response has been deliberate. Prime Minister Mark Carney announced retaliatory tariffs matching U.S. duties dollar for dollar on $20 billion in American goods, effective September 8, with the stated goal of shielding Canadian workers, farmers, and businesses from the economic fallout.
Whether the antitrust freeze represents a calculated escalation or a cautious bureaucratic pause remains unclear. What is evident is that a form of cooperation that once operated quietly beyond the reach of political dispute has now been drawn into the conflict — raising the question of whether it will resume once tensions ease, or whether something more lasting has been broken.
The Justice Department's antitrust division received orders this week to stop all work with Canada. According to emails obtained by The Wall Street Journal, Lynda Marshall, who leads the division's international section, directed staff on Wednesday to suspend cooperation on cases and policy matters with Canadian authorities. No explanation was provided in the directive. By Friday, section chiefs were asked to compile lists of all areas where the two countries were working together, with the inventory due by end of day.
The DOJ pushed back against the reporting. A department statement said the "alleged direction was never given to anyone" and characterized the situation differently: officials had simply been asked to postpone a scheduled meeting on a specific investigation while the antitrust team prepared more thoroughly. The discrepancy between what the emails showed and what the department claimed left the actual scope of the freeze unclear.
The pause in antitrust cooperation sits within a much larger breakdown between the United States and Canada. The two countries have been close partners for decades, but that relationship has fractured since President Trump returned to office in January 2025. His administration has pursued an aggressive trade strategy against Canada, imposing a 50 percent tariff on roughly $20 billion in Canadian goods last month. The tensions have extended into symbolic territory: Trump signed an executive order to rename Lake Ontario to "Lake America" within U.S. federal government usage. While Canada, other nations, and American states are not bound by the rebranding, the gesture underscored the deteriorating tone between neighbors.
Canada's response has been measured but firm. Prime Minister Mark Carney announced that his government would impose retaliatory tariffs beginning September 8, matching the U.S. duties dollar for dollar on $20 billion worth of American goods. The stated aim was to protect Canadian workers, farmers, families, and businesses from the economic impact of Trump's tariffs. The cross-border trade affected by these duties runs into the tens of billions of dollars.
What remains unclear is whether the antitrust division's pause represents a deliberate escalation of the trade conflict or a bureaucratic precaution. The DOJ's denial suggests the order may have been narrower than the emails indicated, or that the department wanted to avoid the appearance of weaponizing law enforcement against a trading partner. Either way, the suspension of antitrust cooperation—a form of technical and legal coordination that typically operates outside the realm of political dispute—signals how thoroughly the trade war has penetrated institutional relationships. As Canada prepares its retaliatory tariffs and both nations dig in, the question is whether this freeze on antitrust work will thaw once the immediate trade tensions ease, or whether it marks a more fundamental rupture in how the two governments interact.
