And: The Federal Liberals are heading into their Montreal convention with one more caucus member. It puts them just one seat away from forming a majority government.

But that new caucus member brings her own political baggage, and stirs questions about whether the party will need to adapt its policies.

A two-week ceasefire between the U.S., Israel, and Iran is under threat. Iran’s parliamentary speaker says several conditions have been violated. The main dispute: whether Israel agreed to stop its incursion in Lebanon. The Strait of Hormuz is closed to traffic, and reports of renewed strikes keep the region on a knife’s edge.

And: The Liberals are one seat closer to a majority government. Ontario Conservative MP Marilyn Gladu has crossed the floor to join the Liberals.

Also: “Feel the burn” is a common motivational phrase when you’re working out. But sometimes that pain is a sign that something is seriously wrong. “Exercise-induced rhabdo”, as it’s known, is caused by the sudden breakdown of muscle tissue. Health reporter Christine Birak tells us how likely it is to occur, and how it could be avoided.

U.S. President Donald Trump threatens Iran with the destruction of its entire civilization.

And: The crew of the Artemis II mission had a call with astronauts on the International Space Station. The Artemis crew travelled farther into space than any other humans, and are now on their way back to Earth.

Hours after celebrating the high stakes rescue of an American airman inside Iranian territory, the U.S. President issued another threat against Iran. In a profane Easter morning post, Donald Trump vowed to target Iran's power plants and bridges. This latest invective has prompted pushback from Iran and from some inside the U.S.

Also: Voters in three federal ridings, two in Ontario, one in Quebec, were out at advance polls this holiday long weekend. Voter turnout was high, especially in Terrebonne - a riding north of Montreal. The results could give the federal Liberals a majority in Parliament, thanks to recent defections from other federal parties.

And: Animal rescue groups are calling on Canada to end its ban on importing rescue dogs from over 100 countries. The temporary ban was brought in in 2022, after two rescue dogs from Iran tested positive for rabies. Organizations say the ban is too heavy-handed. But some vets warn the risk is too great.
