Three federal byelections could mark an important milestone for the Carney Liberals. One win would mean the Liberals would have a majority government.
We look at what’s at stake in today’s vote.

And: The U.S. has imposed a naval blockade on Iran. It went into effect today, after this weekend's talks between the United States and Iran collapsed. The shaky ceasefire is still in effect for another week.

Also: Cancer is still the leading cause of death in Canada. Despite more screening and prevention tools, numerous types of cancer are increasing, according to a new study.

Plus: Drug crisis in British Columbia, Trump vs. the Pope, Ontario restructures school boards, and more.

After marathon peace talks ended without an agreement, the United States is attempting to ratchet up pressure on Iran. President Donald Trump is now threatening to impose a full blockade on the Strait of Hormuz. Meanwhile, the future of an already shaky two week ceasefire hangs in the balance.

Also: Its a historic day for Hungary, as the country elects a new Prime Minister. Viktor Orban conceded defeat in the country's election - after ruling the country for 16 years. His loss to Peter Magyar will likely tilt Hungary away from Russia and closer to its European allies.

And: Quebecers now know who will replace premier Francois Legault. The Coalition Avenir Québec has elected Christine Frechette as their new leader. After a three month race for the top job, Frechette now has to try and revive the party’s fortunes ahead of a fall election.

Plus: How climate change is damaging Darjeeling tea farms, The benefits of strength training for women, and more.

Face to face talks between the United States and Iran are being held in Pakistan. The high stakes discussions take place against a backdrop of a shaky two-week ceasefire between the US, Iran and Israel. As talks are underway, the U.S. military says it is "setting conditions" for reopening the Strait of Hormuz. The waterway has been effectively closed since the war began, blocking a vital trade route.

Also: Today, the federal Liberals wrapped up its national convention in Montreal. Prime Minister Mark Carney used the moment to signal unity and readiness. And come Monday, voters in Canada could tip the political scales on Parliament Hill — with the Liberals now on track to secure a slim majority if they win one of three byelections.

And: In Quebec, three investors say they've found a way to get people back to church: pickleball. They've taken an old, decomissioned church and turned it into a pickleball complex. They say it's a sustainable solution for the hundreds of out-of-use churches across the province. But the project has some doubters.

Plus: Reintroducing Rhinos to Uganda, the studies conducted on the Artemis mission, and more.

The four Artemis II astronauts — including Canadian Jeremy Hansen — return from the world's first crewed moon voyage in over half a century.

And: Canada may have added about 14,000 jobs last month, but younger workers probably didn’t notice. Youth unemployment remains high — double the national average, and the younger the worker, the wider the gap.

Also: Swedish aircraft maker Saab is sweetening the pot to get Ottawa to buy its Gripen fighter jets. The company says it will construct a data centre in Canada to keep mission-critical data within the country. We’ll have more on why that matters in today’s data-driven world.

Plus: U.S. Vice-President JD Vance heads to Islamabad tonight for talks with Iran, Liberals eye a possible majority, opposition to the proposed Alto high speed rail project, and more.

Lebanon is still a major sticking point in the shaky ceasefire between the U.S., Israel, and Iran. And there is little clarity about the Strait of Hormuz. Both the U.S. and Iran have said the passage will reopen. But there’s been very little traffic through the vital shipping route, days into the precarious two-week truce.

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.

Also: The makers of a next-generation AI model say it's too powerful for the public. Anthropic says its new model could enable widespread hacking and lead to cybersecurity risks. What you should know about Claude Mythos.
