Liberal MP and former Environment Minister Steven Guilbeault has announced he will be resigning from his seat this summer, saying he wants to continue fighting against climate change in a “different way.”
In a statement released May 27, Guilbeault said he had informed Liberal caucus colleagues of his decision to step down as MP for the Montreal riding of Laurier–Sainte-Marie, though he will remain in office until “later this summer.”
Guilbeault said he reached the decision after “careful consideration” about his future.
“I have come to the conclusion that it is time for me to pursue my fight for environmental protection and the fight against climate change in a different way,” he said.
Guilbeault served as minister of environment and climate change from October 26, 2021, to March 14, 2025. He subsequently served as minister of Canadian culture and identity before stepping down from cabinet late last year.
Guilbeault said Canada had demonstrated to the world “what we can accomplish with ambition and determination.” Guilbeault said he wanted to use that same conviction to continue fighting for “the generations who will inherit our precious and unique blue planet.”
