Liberal MP Steven Guilbeault Resigns Over Alberta Pipeline Deal

Post by : Mina Carter

Liberal MP Steven Guilbeault has resigned from the federal cabinet following the signing of a memorandum of understanding (MOU) with Alberta to advance a new bitumen pipeline to the B.C. coast.

In a statement, Guilbeault, who served as official languages minister and minister of Canadian identity and culture, said he entered politics to fight climate change and protect the environment. “I remain one of those for whom environmental issues must remain front and center,” he wrote, expressing opposition to the agreement.

The MOU, signed by Prime Minister Mark Carney and Alberta Premier Danielle Smith, outlines Ottawa’s support for a pipeline transporting one million barrels of oil per day from Alberta to a Pacific Coast export terminal, largely for Asian markets.

Guilbeault highlighted environmental concerns, including the suspension of federal oil and gas emission caps and the removal of certain Clean Electricity Regulations, measures he introduced as environment minister. He emphasized his commitment to climate action and a sustainable future.

Under the agreement, Alberta will increase its industrial carbon price from $95 to a minimum of $130 per tonne, while both governments remain committed to achieving net-zero emissions by 2050. Critics note that the deal could accelerate conventional energy production.

Carney described the agreement as “co-operative federalism” and praised Guilbeault’s contributions to cabinet, acknowledging their differences in approach but valuing his ongoing role as a Liberal MP. Guilbeault will continue to represent his Montreal riding in the House of Commons.

Alberta officials welcomed Guilbeault’s departure, while federal Energy Minister Tim Hodgson praised his dedication and achievements. Guilbeault, a former Greenpeace activist and co-founder of Équiterre, has long opposed pipeline projects, including the Trans Mountain expansion.

The resignation has drawn political attention, with Green Party Leader Elizabeth May inviting Guilbeault to join her party, citing his commitment to climate action as a reason for potential collaboration.
