Canadians braced for new tariffs on Wednesday. Instead, U.S. President Donald Trump said he would hold off on 50 per cent tariffs for three more days because a “good” trade deal was in the works. The details of the tentative trade deal remain murky. But Prime Minister Mark Carney is insisting that progress is being made and met with his cabinet and Canada’s premiers on Wednesday afternoon. Whatever the deal entails, the Prime Minister faces a difficult balancing act politically. The Globe’s senior political reporter, Marieke Walsh, explains all the different groups Carney must answer to in this fraught moment and what impact this could have on his political career.

New research from the University of Regina and the University of Alberta provides evidence that Russian content farms and right-wing U.S. influencers are targeting Alberta’s upcoming referendum. Some foreign actors are trying to foment discord in Canada, while others overtly try to persuade Canadians to join the separatist cause. Grant Robertson is an investigative reporter with The Globe. He explains how these campaigns work, what messages these foreign actors are pushing and how ready Alberta – and Canada – are to fight back against them.

More than 6,000 ship workers, including some Canadians, have been stranded in the Persian Gulf — some in the Strait of Hormuz — since the war in Iran began at the end of February. Some workers — also known as seafarers — have been stuck on board without pay, or help from their ships’ owners. With little signs of progress on talks to reopen the Strait of Hormuz, the fate of these workers remains unclear. One of the people they turn to for assistance is Mohamed Arrachedi, a co-ordinator for the International Transport Workers' Federation, a group that represents unions across every sector of global transport. Mr. Arrachedi shares what he’s hearing from these stranded seafarers and the challenges involved in getting them the help they need.

Canada is in the middle of one of its worst seasons for ticks. The tick population and tick-borne diseases are climbing year-over-year, and it’s not just Lyme disease that experts say we should be concerned about. Today, the Globe’s health science reporter Jennifer Yang joins the show to discuss the emergent tick-borne disease causing concern in Canada, why our country’s tick problem is only getting worse, and what we can do to protect ourselves.

GLP-1 medications to treat diabetes, obesity and several other illnesses have exploded in popularity since Ozempic was approved for use in Canada back in 2018. Ozempic and Wegovy, the GLP-1s which contain semaglutide, are the third-most prescribed drug in Canada and by far the bestselling one. Chris Hannay, The Globe’s business of health reporter, will explain why the introduction of generic semaglutide will mean lower prices and more options for Canadians. And we’ll explore access to these drugs with The Globe’s health reporter Kelly Grant on who gets their GLP-1 covered by their insurance – and who doesn’t. Plus, Globe audio producer Kasia Mychajlowycz leads us on a journey to understand just how the virtual pharmacies advertised all over her social-media feed are vetting people who want Ozempic prescriptions.

Summerland, B.C., has been devastated by the Bald Range wildfire. More than 20,000 people have evacuated, and by Wednesday, it had burned 178 square kilometres. The evacuees don’t know when they can return home yet, and many don’t know if their home is standing at all. Today, we bring you conversations with people on the ground about how they fled the fast-moving wildfire, and how they’re coping with uncertainty and loss.

For years, the Canadian athletic-wear brand Lululemon both pioneered and dominated the athleisure retail market. It turned workout gear into a status symbol, growing its international operations to 30 countries. But there’s trouble – a public battle with its founder, controversies over its marketing and a cratering stock price have all amounted to serious problems for the once-stalwart brand. Susan Krashinsky Robertson, The Globe’s retailing reporter, dives into the issues Lululemon faces, crunches the numbers of its financial outlook and asks what happens when a big brand loses its cool.

Canadian banks are leaning heavily into AI adoption. More than 30 per cent of finance and insurance firms are using AI, compared to just 1.5 per cent of businesses in accommodation and food services. The banks are spending millions, in some cases billions, of dollars on AI programs, like chatbots for customers, for employees, and even for a CEO’s morning briefing. Today, we’ve got The Globe’s banking reporter Stefanie Marotta on the show. She’ll explain how banks are using AI (including ways customers don’t ever see), the risks they’re weighing, and what it means for the adoption of AI across Canada.

Steeped in military and naval history, Halifax is increasingly used as the backdrop for announcements of defence investment. The city is poised to benefit from substantial investment thanks to Mark Carney’s commitment to meeting NATO targets. But as more development arrives, is Halifax able to support the demands of an increased strain on its infrastructure and housing supply? Chris Wilson-Smith went there to find out. He’s a business reporter and the author of one of The Globe’s daily newsletters, Business Brief. He’s on the show to explain how Halifax is trying to make sure it makes the most of this moment.

Dr. Daniel Drucker’s research helped pave the way for Ozempic, the blockbuster GLP-1 class drug. The endocrinologist has been researching the effects on Ozempic’s active ingredient semaglutide in the body for decades. Today, he’ll show us around his lab and explain how a stout lizard kept in a freezer helped unlock the science behind a drug taken by more than a million Canadians. Then, health reporter Kelly Grant tells us about rising obesity rates in Canada, and we’ll hear from a doctor who prescribes GLP-1s – and a patient who takes them.
