Liberal MP and former environment minister Steven Guilbeault has announced his resignation from the House of Commons, citing a divergence between his environmental principles and the party's policies.

The resignation follows revelations that 14 Liberal MPs, likely including Guilbeault, sent a letter to Prime Minister Mark Carney accusing the party of failing to uphold its environmental commitments.

Guilbeault, a former Greenpeace activist, has long been outspoken on climate issues and criticized the Canada-Alberta memorandum of understanding on a proposed West Coast pipeline, calling it 'ephemeral' and insufficient.

In his resignation letter, Guilbeault stated his intention to continue advocating for environmental protection and climate action outside of Parliament.

The article notes that his departure may encourage other Liberal MPs to reconsider their alignment with the party’s principles, as recent moves by the Liberals, such as adopting policies similar to the Conservatives and eliminating the consumer carbon tax, suggest a prioritization of political power over environmental or ideological consistency.Guilbeault’s stand highlights the tension within the party between principle-driven advocacy and political pragmatism.
