Mark Carney, the former governor of both the Bank of England and the Bank of Canada, issued a stark warning Sunday that Alberta's planned referendum on seeking greater autonomy from Ottawa risks becoming a "dangerous bluff" that could spiral out of control, drawing explicit parallels to the United Kingdom's Brexit vote and its chaotic aftermath.
Speaking at a campaign event in Toronto—Carney is widely expected to seek the leadership of the federal Liberal Party—the influential economist and central banker said political tools like referendums can "take on a life of their own," creating outcomes that even their proponents neither expected nor desired.
"I watched this happen in the UK," Carney told the audience, according to an account published in the New York Times. "Leaders who thought they could control the process, who treated a referendum as a negotiating tactic, found themselves overwhelmed by forces they had unleashed. Canada should learn from that experience, not repeat it."
Alberta's governing United Conservative Party, led by Premier Danielle Smith, has committed to holding a referendum on establishing an Alberta Pension Plan separate from the Canada Pension Plan, as well as potentially pursuing other measures to assert provincial autonomy, including collecting its own taxes and establishing a provincial police force. While Smith has not explicitly called for Alberta's separation from Canada, the cumulative effect of these measures would substantially reduce federal integration.
The push for greater autonomy reflects deep-seated tensions in Alberta, a province whose economy centers on oil and gas production and whose predominantly conservative electorate has grown increasingly alienated from what many perceive as a federal government hostile to the energy sector. Prime Minister Justin Trudeau's Liberal government has pursued aggressive climate policies, including carbon pricing and restrictions on new fossil fuel development, measures that Alberta politicians across the spectrum view as economically damaging and fundamentally unfair.
To understand today's headlines, we must look at yesterday's decisions. The current tensions are the latest chapter in a long history of western alienation in Canadian politics. Alberta has often felt marginalized within confederation, viewing federal policy as overly influenced by the more populous provinces of Ontario and Quebec. Previous economic downturns in the energy sector have spawned separatist movements, though none has gained sufficient traction to pose a serious threat to national unity.
What makes the current moment different, according to Carney and other observers, is the mainstreaming of autonomy rhetoric within Alberta's governing party rather than its relegation to fringe movements. Smith enjoys strong support within the province, and polling suggests significant public backing for at least some of the autonomy measures under consideration.
Carney's credibility on this issue stems from his unique vantage point. He served as Bank of England governor from 2013 to 2020, a period that encompassed the 2016 Brexit referendum, the tortured negotiations that followed, and the eventual UK departure from the European Union in 2020. Throughout that period, Carney repeatedly warned about economic risks and was often cast by Brexit supporters as part of an establishment opposed to British sovereignty.
The Brexit comparison resonates beyond the surface similarities of referendums and autonomy. In both cases, complex questions of economic integration, identity, and governance are being subjected to yes-or-no votes that may not capture the nuances of the relationship at stake. Brexit demonstrated that even non-binding referendums create political momentum that is difficult to resist, and that unraveling decades of integration is far more complicated than proponents suggested.
Dr. Kathleen Mahoney, a constitutional law professor at the University of Calgary, told the CBC that Alberta cannot unilaterally establish many of the measures Smith has proposed without federal cooperation or constitutional amendments requiring broad consensus. "What concerns me is that we're having a political debate that may create expectations that legally cannot be met," Mahoney said. "That's a recipe for frustration and further radicalization."
Premier Smith's office responded to Carney's comments by accusing him of "fearmongering" and insisting that Alberta has every right to pursue policies that serve its citizens' interests. "Mr. Carney would do well to ask why so many Albertans feel the need to assert their autonomy," a spokesperson said. "Perhaps the problem isn't Alberta's democratic choices but Ottawa's refusal to listen."
The exchange highlights the deepening polarization in Canadian politics around energy policy, climate change, and regional identity. Carney's expected entry into federal politics as a potential prime minister-in-waiting adds another dimension: his warnings about Alberta autonomy may be sincere, but they also serve to position him as a unifying figure who understands both the economic and the emotional dimensions of national cohesion.
For Canada, a country that has faced existential questions before—particularly around Quebec sovereignty—the Alberta question presents a different kind of challenge. Unlike Quebec's distinct linguistic and cultural identity, Alberta's grievances are primarily economic and political. Yet that may make them harder, not easier, to address, as they require substantive policy changes rather than symbolic recognition.
As Carney concluded his remarks Sunday, he returned to the Brexit theme. "Referendums can't be treated as negotiating tactics or political theater," he said. "Once you ask people to vote on their future, you have to be prepared to accept the answer—and to live with the consequences. Britain learned that the hard way. Canada should be wise enough to learn from others' mistakes."
