Hello, welcome to Politics Insider. Let’s look at what happened today.


Former Liberal environment minister Steven Guilbeault is expected to announce he is leaving Prime Minister Mark Carney’s caucus as early as Wednesday, two Liberal sources told The Globe and Mail.

Marieke Walsh and Stephanie Levitz report that the sources said that they expect the career environmentalist from Quebec will also quit as a member of Parliament, though one of them cautioned that plan could still change.

Guilbeault has represented the downtown Montreal riding of Laurier-Sainte-Marie since 2019.

Three other sources said Guilbeault is expected to address Parliament on Wednesday. One of those sources said Guilbeault has also scheduled a gathering with current and former staff after his speech in the House of Commons.

The Globe and Mail is not identifying the sources, who were not authorized to discuss the confidential plans.

Guilbeault resigned from Mr. Carney’s cabinet in November over his disagreement with the government’s energy accord with Alberta and its dismantling of marquee climate policies from the Trudeau era.

Expectations that Guilbeault would break entirely with the Liberals have ramped up in recent weeks, as Carney solidified his agreement with Alberta Premier Danielle Smith to clear the way for a new oil pipeline to the West Coast and overhaul and speed up environmental assessments.

In other news, India’s top diplomat in Canada says CSIS has been politically compromised and that the RCMP are investigating “fantasy” allegations that Indian officials are involved in crimes against Canadians.

Greg Mercer and Mike Hager report that, in a sweeping interview with The Globe and Mail, High Commissioner Dinesh Patnaik went on the offensive, attacking the integrity of Canada’s national-security agencies, while pushing back against assertions from Canadian authorities that the government of India has directed multiple homicide plots and foreign-interference campaigns on Canadian soil.

Patnaik asserted that the Canadian Security Intelligence Service has been compromised by Sikh separatists using Canada as a base for their campaign to carve out a breakaway state in northwest India, which they call Khalistan.

He said the investigation into the 2023 slaying of B.C. activist Hardeep Singh Nijjar has been “twisted around” and politicized – adding that while the RCMP is an “independent, very good organization,” in the past the force had been “susceptible to political direction.”

Quotes of the Day

“So, I’m a good friend of Steven. I have worked a lot to bring him in politics and he will always be a good friend. I also think that I’m part of much more the environmentalist part of – of the Liberal Party and cabinet, but I also think that what we’ve done with the MOU makes sense, because I also think that we need to be able to have one of the most important provinces that is the main energy producer in Canada part of our plan." - Industry Minister Mélanie Joly, arriving for today’s cabinet meeting, comments on the prospect of former environment minister Steven Guilbeault leaving the Liberal caucus.

One night I am sitting there and they must have made a kill because they are screeching. I don’t know if you’ve ever heard them, but they’re screeching. So I went out there and howled like a wolf. They stopped instantly. Honestly. I’ve got to tape this for you guys. So they figured the big wolf is around the corner.” - Ontario Premier Doug Ford, at Queen’s Park in Toronto, talks to journalists about a coyote problem in his neighbourhood.

A ban won’t shield kids from social media

It would be wonderful if we could take childhood back from the social-media giants with a simple ban. Sadly, the actual work needed to protect children is much harder. That work should respect teenagers’ autonomy but also recognize their vulnerability and the need for protection.

An `independent’ Alberta would be a way station on the path to 51st statehood

If you think building a new pipeline to tidewater is challenging as part of Canada, try to get your head around how difficult – by which I mean impossible – it will be if Alberta becomes a landlocked statelet.
