Prime Minister Mark Carney’s appointment of Maia Johnson as the first chief operating officer of the Prime Minister’s Office has produced two competing interpretations.
The first is that Carney has promoted an experienced political operator who already understands his working style, American institutions, and the Canada-US relationship into a role designed to improve coordination inside the PMO.
The second is considerably darker. Critics portray Johnson as an unelected American political strategist who has been placed in control of the prime minister’s office after failing to comply with federal ethics requirements.

Why a COO?
Johnson’s promotion is part of a wider restructuring of Carney’s senior political operation. The Canadian Press reported on July 13 that Johnson would become the PMO’s chief operating officer while remaining a senior adviser on Canada-US relations. Scott Gilmore, previously Carney’s senior adviser on foreign, defence, and security policy, is also moving into the principal secretary position.
She had worked with Carney on climate-finance policy years before joining the Prime Minister’s Office. In a March 2022 lecture on climate and macroeconomic policy, Carney thanked Johnson and several colleagues for helping prepare the address. At the time, Carney was serving as the United Nations special envoy on climate action and finance.
The moves suggest Carney is formalizing a more corporate management structure inside the PMO.
Unlike a government department, the PMO is the prime minister’s political office. It supports the prime minister with communications, policy advice, political strategy, stakeholder relations, scheduling, and coordination with ministers, departments, and the governing party. The PMO does not independently exercise the statutory authority of cabinet ministers or the professional responsibilities of the federal public service. It can nevertheless exert enormous practical influence because it controls access to the prime minister and helps determine which priorities receive political attention.

A chief operating officer would ordinarily manage the internal machinery needed to turn leadership decisions into coordinated action. Depending on how Carney defines the position, that could include staffing, workflow, project management, information sharing, scheduling, implementation, and coordination between senior advisers.
At first glance, the title may appear redundant. As Canada’s head of government, the prime minister already directs the government’s political agenda and oversees the work of cabinet. The newly created chief operating officer role does not transfer those constitutional responsibilities. Instead, it appears to import a corporate management structure into the Prime Minister’s Office itself, focusing on the coordination of staff, internal operations, and execution of priorities rather than the exercise of governmental authority.
The creation of a chief operating officer also raises an obvious question about whether Johnson’s position duplicates work normally performed by Carney’s chief of staff, Marc-André Blanchard. Parliamentary guidance describes the chief of staff as the head of the PMO, responsible for overseeing its personnel, advising the prime minister, controlling access, and coordinating with the Privy Council Office. A COO would ordinarily focus more narrowly on internal systems, workflow, staffing, and the execution of decisions, leaving the chief of staff to concentrate on political strategy and senior advice.
However, because the PMO has not published Johnson’s job description or explained how authority will be divided between her and Blanchard, it remains unclear whether the new role creates a genuine operational separation or merely adds another senior official to responsibilities already associated with the chief of staff.
The information gap is one reason the appointment has generated more controversy than an ordinary personnel change.
Who Is Maia Johnson?
Federal records identify Johnson as senior adviser for US stakeholder strategy in the Prime Minister’s Office. She entered the position on February 17, 2026. The government directory similarly lists her as the PMO’s senior adviser responsible for US stakeholder strategy.
Her title indicates a focus on relationships with American political, business, and institutional actors rather than formal diplomatic negotiations. Foreign policy remains the responsibility of the prime minister, cabinet, the foreign affairs minister, and Canada’s diplomatic service.
Public lobbying records show that Johnson has already participated in meetings involving major Canadian institutions and companies.
A May 26 communication involving Imperial Oil listed Johnson as a designated public office holder and described the subjects as industry and national security. Other federal lobbying records show her participating in discussions involving research, development, and government policy.
Her earlier political work is also relevant. Records from Hillary Clinton’s 2016 presidential campaign show a Maia Johnson using a hillaryclinton.com email address and participating in campaign communications, disclosed in WikiLeaks.
Johnson’s strongest apparent qualification is the combination of three forms of experience: she has worked inside American politics, has an existing professional relationship with Carney dating to his international climate work, and has already been managing US stakeholder relations from inside his office.
For a prime minister navigating trade, defence, tariffs, industrial policy, and an unpredictable relationship with Washington, familiarity with American political networks can be an asset rather than a disqualification.
The counterargument is that the same background could create divided-loyalty concerns or at least the appearance of them. That concern becomes sharper when the adviser reportedly holds American citizenship and remains responsible for Canada-US relations.
What’s wrong?
With the move, conservative commentator Mario Zelaya claimed that an American with Democratic political experience had been placed in charge of the PMO after being fined by the ethics commissioner.
Several elements are factual. On June 25, months into the PMO adviser position, the Office of the Conflict of Interest and Ethics Commissioner disclosed that Johnson had been assessed a $200 administrative monetary penalty after failing to provide all information required for her confidential compliance report within 60 days of becoming a reporting public office holder. According to the commissioner, the penalty related to a breach of the Conflict of Interest Act, and the public registry indicates the fine has since been paid.
The office lists her initial compliance process as ongoing.
However, the ethics finding does not prove that Johnson hid a conflict of interest, failed to disclose a specific asset, benefited financially from government decisions, or acted improperly on behalf of an American organization.
The commissioner’s notice identifies a failure to provide required information within the prescribed period. It does not publicly identify the missing information or make a finding of corruption. The penalty was administrative, not criminal.
Critics also describe her appointment as the first time in Canadian history that a prime minister has installed a COO. While the position is new to the current PMO structure, it does not conclusively establish that no comparable operational role has ever existed under a different title in any previous prime minister’s office.
There is no legal barrier preventing a prime minister from creating a chief operating officer position within the PMO. The office is organized at the prime minister’s discretion, making the controversy one of governance and political accountability rather than constitutional authority.
Historically, Canadian prime ministers have relied on a Chief of Staff to manage both political strategy and much of the PMO’s internal operations. By introducing a separate COO, Carney appears to be borrowing a corporate management model that distinguishes operational management from political leadership.
The political risk
However, that move could also be a source of Carney’s immediate problem on optics. He has presented himself as the leader best equipped to protect Canada’s economy and sovereignty in dealings with the US. Promoting a reported US citizen with Democratic campaign experience to a central PMO position allows opponents to argue that his government’s internal structure contradicts its public message of Canadian autonomy.
The criticism is politically potent because it combines several sensitive themes: an unelected adviser, American nationality, partisan connections, an ethics penalty, and a newly created title with undefined authority.
For Canada, the more important institutional question is whether access to the prime minister and responsibility for Canada-US strategy are being concentrated without sufficient public accountability.
Set aside Johnson’s nationality, but the more salient issue is asking Canadians to trust a new power structure inside the PMO before the government has adequately explained how that structure works.
