Canadian Prime Minister Mark Carney has warned of the risks associated with heavy reliance on a limited number of U.S.-based artificial intelligence providers following recent export restrictions on advanced AI models. His comments come in response to measures taken by the Trump administration that have forced Anthropic, a San Francisco-based AI company, to disable access to its latest models, Fable 5 and Mythos 5, for foreign nationals.

Anthropic announced on Friday that it had withdrawn these models to comply with new U.S. government restrictions, marking the most significant effort yet by Washington to control the dissemination of cutting-edge AI technologies. The export controls aim to limit the use of advanced AI capabilities abroad, with Anthropic citing concerns about the sophisticated security risks posed by its Mythos model, which reportedly surpasses human experts in identifying and exploiting cybersecurity vulnerabilities. While Fable 5 was released more broadly last week as a limited version of Mythos, access to the latter remains tightly controlled.

Speaking from Westport, Ireland, ahead of the Group of Seven summit in Evian-les-Bains, France, Carney framed the situation as an example of the vulnerabilities created by overdependence on a narrow pool of AI providers. “Nobody has done anything wrong in the situation. But we will have done something wrong if we just accept this, don’t take the lesson, don’t build out and diversify,” he said. Carney emphasized the importance of expanding options in AI development and access to reduce risks tied to supply concentration.

AI and its regulation are expected to be key topics during discussions among the G7 leaders. Carney noted he had recently spoken at length with French President Emmanuel Macron about the challenges posed by advanced artificial intelligence and highlighted the complexity of the issues, suggesting no immediate resolutions would emerge from the summit.

Carney also linked the AI export restrictions to broader concerns over Canada’s economic exposure to the United States. With over 70 percent of Canadian exports currently destined for the U.S., he reiterated his goal to double Canada’s non-U.S. exports within the next ten years as part of a diversification strategy. He pointed to ongoing tensions stemming from the Trump administration’s trade policies, which have dampened investment and raised uncertainties.

Regarding the pending renewal of the North American free trade agreement, Carney said he did not have bilateral meetings scheduled with President Trump during the G7 summit. Instead, trade talks are expected to continue among designated negotiators from Canada and the U.S., including Minister Dominic LeBlanc, chief negotiator Janice Charette, U.S. Trade Ambassador Jamieson Greer, and Treasury Secretary Scott Bessent. “The right way to do it at this stage will be between the principal negotiators, which is going to happen in Evian,” Carney said.
