Liberal MP Steven Guilbeault has dramatically resigned from Prime Minister Mark Carney's cabinet, citing his strong opposition to Ottawa's approval of an Alberta pipeline project. The resignation occurred on Thursday, November 27, 2025, creating political ripples through the federal government.
Principle Over Position
Guilbeault's departure stems directly from the energy agreement signed between Prime Minister Carney and Alberta, which lays out conditions for constructing a new oil pipeline. The environmental advocate and longtime pipeline opponent stated he could not, in good conscience, remain part of a government that approved such a project.
Despite this high-profile resignation, Liberal MPs are publicly maintaining that their party remains united. Colleagues have praised Guilbeault for his principles while emphasizing that the government must balance environmental concerns with economic realities.
Political Fallout and Reactions
The energy agreement with Alberta has generated mixed responses across the political spectrum. While many environmental groups and some political leaders oppose the pipeline plan, others see economic opportunity in the project.
This resignation marks one of the first significant political challenges for Prime Minister Mark Carney's administration. The timing is particularly sensitive as the government attempts to navigate Canada's complex energy and environmental policy landscape.
Broader Implications
The situation highlights the ongoing tension within Canadian politics between resource development and environmental protection. Guilbeault's resignation underscores the deep divisions that persist regarding fossil fuel infrastructure projects.
Fellow Liberal MPs have quickly moved to contain potential damage, insisting that while individuals may disagree on specific policies, the party remains cohesive and focused on governing. The coming days will reveal whether this incident represents an isolated disagreement or signals deeper fractures within the governing party.
As Parliament continues its work, all eyes will be on how the Liberal caucus manages this internal disagreement while advancing the government's agenda, particularly on energy and environmental files where Guilbeault was a prominent voice.
