Former environment and climate change minister Steven Guilbeault is reportedly considering resigning from the Liberal Party caucus, according to federal government sources. The CTV News report indicates that Guilbeault is concerned about the current government's rollback of Trudeau-era climate policies and the recent memorandum of understanding with Alberta regarding a new pipeline.
Guilbeault, who previously served as Minister of Canadian Identity and Culture under Prime Minister Mark Carney, resigned from cabinet in November 2025 over similar disagreements regarding energy policy. At that time, he voiced strong opposition to Carney's energy deal with Alberta, particularly concerning a potential new oil pipeline. Despite his resignation from cabinet, Guilbeault remained a Liberal MP.
Sources close to Guilbeault suggest he feels Canada's 2050 net-zero emissions target is now unattainable due to the rollback of the oil and gas emissions cap and related regulations. More than a dozen Liberal MPs recently wrote to the Prime Minister expressing concerns about changes to methane and clean electricity regulations in Alberta, moving the $130 per-tonne effective price on carbon target beyond 2030, and the possibility of public funds going towards a new pipeline.
Guilbeault, a prominent Quebec politician and former environmental activist, has been a vocal advocate for strong climate action. His potential departure would signal further internal divisions within the Liberal Party regarding its approach to environmental issues and energy policy.
