Shortly after the accident, Air Canada's Michael Rousseau released a video of condolence on X, but only in one of Canada's two official languages, English, despite the fact that one of the two men who died, Antoine Forrest, was from French-speaking Quebec.

This has outraged many in a country where more than one in five people speak French.

Canada's Parliamentary Committee on Official Languages summoned the airline boss to explain himself before MPs.

And the Prime Minister Mark Carney has waded into the row, saying Mr Rousseau's response showed a lack of compassion and calling on him to step down.

Mr Rousseau lives in Montreal, but despite his name, is an Anglophone.

It's not the first time he's been criticised for his lack of French.

When he was appointed as CEO of Air Canada in 2021, a journalist asked him why he hadn't learned the language, despite living in Quebec for more than a decade.

His response, that he didn't have the time, sparked outrage.

He later apologised and promised to learn French.

Mr Rousseau is until 1 May to appear before the committee.

Amid concerns that safety failures may have been to blame for the accident, the row has sparked a fresh debate about linguistic inclusivity in Canada.

Deep underground in a cave in the UK, a discovery has changed our understanding of the evolution of dogs and when they became man's best friend.

Our science correspondent Pallab Ghosh visited the site.

It's been pushed back because of a genetic analysis of a jawbone, long thought to have come from a wolf, but now shown to be one of the first dogs, living closely with humans here 15,000 years ago.

Now to another historic discovery.

You may think that d'Artagnan is just a fictional character in The Three Musketeers, Alexandre Dumas' tale of dashing French soldiers in the court of Louis XIV.

But there was a real-life d'Artagnan who was the inspiration for the hero of the novel that has entranced generations of readers and spawned dozens of movies and TV shows.

For more than 350 years, his final resting place has remained a mystery.

Now archaeologists who have spent decades searching for his grave think that they've found it under the collapsed floor of a church in the Netherlands.
