Miller named new culture minister as Carney fills gaps left by Guilbeault

By Canadian Press on December 1, 2025.

OTTAWA — Prime Minister Mark Carney named Montreal MP Marc Miller as the new minister of Canadian identity and culture this afternoon.

Miller was in former prime minister Justin Trudeau’s cabinet between 2019 and 2025 but was not included in Carney’s cabinet until now.

He replaces Steven Guilbeault, who quit cabinet on Thursday following Ottawa’s new pact with Alberta on a proposed pipeline.

Government Transformation Minister Joël Lightbound replaces Guilbeault as Carney’s Québec lieutenant, while Environment and Climate Change Minister Julie Dabrusin is now also responsible for the nature portfolio.

Guilbeault served as environment minister for four years before Carney became prime minister, and was also the heritage minister from 2019 to 2021.

Miller also has been named minister for official languages.
