A political tremor shook Ottawa late Thursday as Steven Guilbeault, a former environment minister and long-time activist, resigned from cabinet. The move followed what sources describe as a direct and uncompromising conversation with Prime Minister Mark Carney regarding a newly signed agreement with Alberta.
Guilbeault, a figure synonymous with environmental advocacy, publicly stated his commitment to fighting climate change and protecting Canada’s natural spaces. He acknowledged the progress made under the previous administration, but expressed deep reservations about the direction the current government is taking.
At the heart of the conflict lies a memorandum of understanding (MOU) between the federal government and Alberta. Guilbeault vehemently opposed the agreement, characterizing it as a betrayal of core environmental principles and a step backward for Canada’s climate goals.
A key concern is the perceived lack of consultation with British Columbia and its Indigenous nations regarding potential pipeline expansion to the West Coast. Guilbeault warned that such a project would dramatically elevate the risk of environmental disasters in a sensitive region.
He also sharply criticized the MOU’s provision to exempt Alberta from federal clean electricity regulations, labeling it a “serious mistake” with far-reaching consequences. This, coupled with the dismantling of initiatives like consumer carbon pricing and the internal combustion engine ban, proved to be a breaking point.
Despite his resignation from cabinet, Guilbeault intends to remain a Member of Parliament, continuing to represent his Montreal-area constituents. He will continue to advocate for environmental protection from within the Liberal party.
The resignation comes on the heels of reports suggesting Guilbeault’s growing discontent with the government’s renewed focus on oil and gas pipelines – a stark departure from the environmental policies championed by his predecessor. Alberta’s Premier, Danielle Smith, has openly stated that previous policies were hindering energy investment.
Guilbeault’s journey to Parliament was unconventional. Before entering politics, he was a prominent environmental activist, co-founding the organization Équiterre and later becoming a leading figure in Greenpeace’s climate change campaign.
His activism wasn’t confined to policy debates. In 2001, Guilbeault famously scaled the CN Tower, unfurling a banner to protest the U.S. and Canadian governments’ reluctance to ratify the Kyoto Protocol – a bold act that cemented his reputation as a fearless advocate for the environment.
Elected to represent Laurier—Sainte-Marie in 2019, he initially held the Canadian Heritage portfolio before being appointed Environment Minister in 2021. He was later moved to the position of Minister of Canadian Culture and Identity, Parks Canada and Quebec Lieutenant earlier this year.
The resignation signals a significant ideological rift within the governing party and raises questions about the future of Canada’s environmental policies under the current leadership.
