Former environment minister, Steven Guilbeault, has left Prime Minister Mark Carney’s cabinet.

It follows a memorandum of understanding between Canada and Alberta for new energy projects, including a pipeline.

In a statement posted on social media on Thursday, Guilbeault said he submitted his resignation to the prime minister.

“As you know, I chose to enter politics to champion the fight against climate change and the protection of the environment,” said Guilbeault in the statement.

“Over the past ten years, our country has made historic progress in reducing climate pollution, protecting nature and the environment while our economy continued to grow. I believe I had contributed to these advancements, and I remain deeply proud of the achievements I helped bring forward.”

He added that despite change in Canada’s relationship with the United States, the environment must remain front and centre.

“This is why I strongly oppose the memorandum of understanding between the federal government and the government of Alberta,” said Guilbeault.

He added that a pipeline to the west coast would have major environmental impacts.

Guilbeault will continue in his role as MP and thanks the prime minister for serving in his role as lieutenant in Quebec.
