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.

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.

With a Quebec provincial election on deck this fall, and the Parti Québécois leading in the polls, there’s a good chance Quebec will hold another referendum on independence. Support for separation is polling at around 30 per cent — far below the majority vote result needed to form an independent country. However, a new generation of sovereigntists is cropping up, one that hadn’t even been born for the last referendum, in 1995.

Maura Forrest is a Quebec correspondent for The Globe and Mail. She’s on the show to talk about what Gen Z sovereignty looks like, how it differs from previous movements, and the implications for the upcoming election.

A Canadian woman has been arrested and accused of spying for a third country during her internship at NATO’s headquarters in Belgium. The woman had a work history with Canadian government agencies and was once found to have committed fraud when trying to apply for a job with the Canada Border Services Agency.

This case is now raising questions about how the Canadian government vets its candidates, especially for roles that could have access to sensitive information. Greg Mercer is an investigative journalist with The Globe and one of a team of reporters working on this story. He joins the show to explain what we know so far.
