Steven Guilbeault, a leading figure in Canada’s environmental movement and a former Liberal cabinet minister, declared his intention to step down from his parliamentary seat this summer. His departure signals growing tensions within the Liberal caucus over the government’s approach to climate change, which Guilbeault has criticized as increasingly inconsistent with urgent environmental action.
Guilbeault explained that after more than seven years representing Laurier-Sainte-Marie, he decided to continue his climate advocacy outside of Parliament. His decision followed the recent federal-provincial energy agreement between Prime Minister Carney and Alberta Premier Danielle Smith, which notably included support for a new pipeline to the West Coast and a slowdown in industrial carbon pricing measures. Guilbeault has publicly opposed this deal and other adjustments that roll back key climate initiatives enacted during his time as environment minister.
He highlighted the dismantling or expected removal of several climate policies he helped establish, including consumer carbon pricing, zero-emission vehicle standards, emissions caps for the oil and gas sector, fossil fuel subsidy elimination frameworks, and clean electricity regulations. Despite his resignation announcement, Guilbeault will remain a Liberal MP until his formal departure.
Prime Minister Carney expressed respect for Guilbeault’s choice, thanking him for his years of service and collaboration. When questioned about the cost of the Alberta deal in light of Guilbeault’s resignation, Carney affirmed the agreement’s value. Meanwhile, Green Party Leader Elizabeth May lamented the environmental advocate’s exit, questioning whether the Liberal Party still accommodates strong climate voices as other MPs with environmental backgrounds also plan to leave.
The Liberals currently hold a slim majority in the House of Commons, and recent reports revealed internal dissent among some MPs, including a letter signed by fourteen Liberals expressing concern over the Alberta energy pact. Guilbeault’s resignation thus highlights internal party conflicts between economic and climate priorities amid the government’s evolving policy landscape.
