Prime Minister Mark Carney’s relatively new government is facing a steady queue of corporate supplicants—many allegedly tied directly to his own investment history. Since he took office, nine companies in which he once held disclosed stakes have registered lobbying contacts with his office.
The Conflict of Interest Commissioner released a list Friday of 567 entities that Prime Minister Mark Carney had previously disclosed stakes in, all parked in a third-party–managed account he could not influence. An additional 103 companies are now fenced off under an ethics “screen,” barring Carney from any involvement in decisions that might advantage their interests.
Yet the distance is proving porous. Ethics scholar Ian Stedman calls the blind trust defence thin.
“Carney has no idea if he continues to hold those funds or not,” he told reporters. That ignorance, he added, “doesn’t erase the optics.”
The Brookfield nexus
Three of the busiest lobbyists—NorthRiver Midstream, Inter Pipeline, and nuclear-equipment maker Westinghouse Electric—share a common owner: Brookfield Asset Management, where Carney served as vice-chair until last year. NorthRiver and Inter Pipeline co-signed an April 30 open letter urging the prime minister to “speed up resource development.”
Days later, both fell under a 103-company “screen” that bars Carney from dealings likely to confer “undue benefit.”
Westinghouse, Inter Pipeline, & NorthRiver are now in his "screen."

So they acted quick to get their face time before the screen went into effect.

The Cameco wrinkle
Screen or not, influence could often find a side door. Cameco, which owns 49% of Westinghouse, logged three direct meetings with Carney between March 19 and June 27 and another pair with PMO advisers in May. Cameco spokesperson Veronica Baker insists the contacts focused on CEO Tim Gitzel’s seat on the Canada–US Relations Council, not Westinghouse strategy.
Opposition Leader Pierre Poilievre is unconvinced. In a statement Monday he warned that Carney’s climate-and-energy platform “lines up with major Brookfield investments.” Even if the prime minister recuses himself from case-by-case files, Poilievre argued, “broader policy initiatives that advance these sectors will directly benefit his future earnings.”
Defence, tech, streaming
The lobby surge is not confined to energy. Ford Motor Company sought relief from US steel tariffs in April; Lockheed Martin pressed PMO staff over defence procurement reforms in June, one month after Carney unveiled a $9-billion military rebuild and ordered a review of the $19-billion F-35 contract; and Spotify pleaded for a lighter hand under the new Online Streaming Act while testifying at CRTC hearings.
Each firm appeared among the 567 undisclosed third-party holdings yet escaped the screen’s stricter glare. The arrangement illustrates what Thurlow calls “the blunt edge of ethical architecture.”
Guardrails with gaps
Under the Conflict of Interest Act, senior officials must divest “controlled assets” within 120 days or bury them in a blind trust. Carney chose the latter. A formal screen now tasks his chief of staff and the clerk of the Privy Council with keeping him clear of Brookfield, Stripe, and selected subsidiaries.
If a file breaches the firewall, Carney must step out of the room.
Political law specialist W. Scott Thurlow calls the arrangement “responsible” yet imperfect. Carney may still vote on any measure “of general application.” That carve out covers everything from sweeping tax changes to a multibillion-dollar infrastructure bill—policies that can lift portfolio companies without ever naming them.
