Prime Minister Mark Carney, former Bank of England governor, warned Alberta’s planned October referendum could backfire, comparing it to Brexit’s lingering economic impact. His remarks follow Premier Danielle Smith’s push for a secession poll.

Smith’s proposal faces criticism from both sides. Pro‑independence activists claim the question robs Albertans of a genuine choice, while federal supporters argue the wording itself is provocative. A recent Angus Reid poll shows 35% of Albertans favor secession, a rise from the typical 25‑30% range.

Carney’s comments signal a shift in Ottawa’s stance toward Alberta’s oil‑heavy economy. He has worked with Smith on pipeline plans, yet now questions the referendum’s democratic legitimacy. The debate highlights tensions over federal oil regulations and tax contributions that fuel separatist sentiment in the province.

If the vote passes, Alberta could face economic uncertainty as investors weigh the risk of a split. The federal government may need to negotiate new trade and tax arrangements, while oil companies could reassess pipeline projects. The outcome will test Canada’s unity and the resilience of its resource sector.
