Mark Carney’s Alberta energy deal is beginning to show the political carrying cost of turning regulatory relief into an investment strategy.
CTV News, citing unnamed federal government sources, reported that former cabinet minister Steven Guilbeault may leave the Liberal caucus within days. The possible move has not been publicly confirmed by Guilbeault or the Prime Minister’s Office, but it would extend a split that began when Guilbeault quit cabinet on November 27, 2025, after opposing Carney’s energy agreement with Alberta.
The Canada-Alberta memorandum of understanding gives the market what years of industry complaints had demanded: a clearer path away from several federal climate-policy constraints. Ottawa said in the MOU that it would not implement the oil and gas emissions cap, which had not yet taken effect. The agreement also covers Alberta’s industrial carbon pricing system, clean electricity rules, carbon capture, data-centre development, and a possible new export pipeline to the BC coast.

Reuters reported last week that oil and gas executives now view Canada’s investment climate as improving under Carney, helped by the Alberta deal’s clearer carbon-pricing framework, faster approval commitments, and support for a potential 1-million-barrel-per-day crude pipeline to BC. But the same report noted that no company has committed to build the pipeline and that the broader package could require around $100 billion in new investment.
That makes Guilbeault’s possible exit more than an internal personality clash. The government is absorbing a real caucus and brand hit before the central economic payoff has been secured. The pipeline has no confirmed private-sector backer. Alberta is expected to move its proposal by July 1. Construction, if it ever proceeds, has been targeted for September 2027.
Guilbeault’s importance is symbolic, but not decorative. He was one of the most recognizable Liberal figures tied to climate policy, having served as environment minister under former Prime Minister Justin Trudeau before becoming a Carney cabinet minister. When he resigned from cabinet, Reuters reported that he said environmental issues needed to remain “front and center” and that he strongly opposed the federal-Alberta MOU.
Leaving cabinet separated him from the policy. Leaving caucus would separate him from the team carrying it.
The political risk is that Carney’s government ends up defending a bargain whose concessions are immediate while its promised investment remains conditional.
That is why Guilbeault’s next move matters. It would put a public Liberal name on the central contradiction of Carney’s energy reset: the government is trying to sell Canada as a lower-risk oil and gas jurisdiction while still asking climate voters to believe the destination has not changed.
