Confronting 'Housing Inc.' | Meet the 2026 CBC Massey Lecturer 08.06.2026

Our homes have been stripped of their essential humanity, says Leilani Farha, this year's CBC Massey Lecturer. Today housing has become a commodity — one fuelling the biggest industry in the world. In her lectures, Housing Inc.: A Global Takeover and Our Fight for Home , Farha calls on all of us to envision a new ideology for home — one rooted in dignity, humanity and law. “Home is required for hu...

Weekend Listen: Artificial Intimacy from CBC’s Understood 06.06.2026

From people who’ve married their bots or who grieve their loved ones with the help of AI, host Victoria Hetherington (author of The Friend Machine) dives into the stories of the people who have invited these digital avatars into their hearts, minds, and even beds. And asks what do we gain and what do we stand to lose? Our intima...

That's 21,954.8 days and that translates to 60 years of listening to us. So what better way to mark IDEAS ' 60th year then to look back on the highlights and lowlights of the past six decades.

How IDEAS saved a listener from sending a regrettable email 04.06.2026

" IDEAS is often a surprise" says Cathy Pike. It's why she's been a longtime listener. To our delight, IDEAS was there for her just at the right time. After listening to an episode about Friedrich Nietzsche and his philosophy about "the art of passing by," Cathy says she decided not to send an email that she realized she would have regretted. "The program gave me pause and I’m grateful for th...

CBC Massey Lecturers reveal how the talks changed them 03.06.2026

This podcast features an all-star, and bestselling, lineup of CBC Massey Lecturers from the past decade: Payam Akhavan (2017) and the police officer who pulled over to the side of the road to keep listening; Sally Armstrong (2019) and the women’s rights groups listening to her talks in Afghanistan, Bangladesh and China; Ron Deibert (2020) and his conviction that ‘philosophical’ radio is more cruci...

The time when a guest said, "I love you!" 02.06.2026

That's not something you expect to hear in an interview. But the Harvard historian and author of All That She Carried , Tiya Miles did not hesitate to say these words to IDEAS host, Nahlah Ayed. What prompted the bold statement comes down to a question — seemingly for Miles the perfect one to ask. Their conversation resonated with many listeners, including a potter in Australia who shares how this...

How an IDEAS episode on traffic changed a doctor's practice 01.06.2026

Not many people like to think about traffic but Joanna Oda says this very topic on  IDEAS in 2005 permanently changed the way she views medical care as a doctor. "It helped me understand how things that make sense for you as an individual contribute to a collective problem." She adds, the episode introduced her to the idea that one car has a big impact. This episode is the first episode in ou...

The most important numbers in the universe 29.05.2026

So... who wants a pipeline? 28.05.2026

For the past decade, Canadians have been split 50/50 on new pipelines — that's changed. Two recent opinion polls found roughly three quarters of eligible voters in Canada want at least one new pipeline built to export more fossil fuels. Yet, 70 per cent of people consider climate change a serious threat. IDEAS producer Tom Howell explores the incompatibilities and future scenarios. *This episode o...

How port cities like Alexandria shaped the world 27.05.2026

Alexandria has been the source of invention, innovation, and beauty for millennia — capturing the imagination of Napoleon, the Prophet Muhammad and, of course, Alexander the Great. He envisioned a place that thrived on cultural, intellectual, economic, political and religious exchange. IDEAS examines the big ideas of this port city in Egypt with Islam Issa, author of Alexandria: The City That Chan...

The real reasons why more young women freeze their eggs 26.05.2026

Egg freezing is considered a kind of "fertility insurance" for the future — a way to buy more time to make a decision about having a family. However, as IDEAS contributor Alison Motluk discovers, uncertainty around parenthood is just one of many reasons why egg freezing is one of the fastest-growing reproductive technologies in the world. She explores those reasons and digs into the social politic...

What does it mean for a river to be ‘alive’? 25.05.2026

Renowned natural history writer Robert Macfarlane traveled to Ecuador, India and Quebec, pondering the question of whether rivers are living beings — the premise behind much of the movement to legally recognize the rights of nature. He found that the answer to that question is more complicated and wondrous — and more life-altering and world-changing — than he could have imagined. *This episode ori...

Why there's no place like Oz 22.05.2026

Even if you aren't a fan of Frank L. Baum's The Wonderful Wizard of Oz , you know about the Tin man, the ruby red shoes and that the dog is named Toto. The classic story was an instant bestseller in 1900 and its popularity is still going strong with not one but a two-part prequel. For over 125 years, there have been derivative works of Oz, from Broadway musicals, films, comic books and more. IDEAS...

Escaped slaves, pirates and 'free love' in ancient history? 21.05.2026

Ancient history just got an upgrade. Forget the ruins, empires and great thinkers of the Classical period and make way for escaped slaves, subversive pirates, and freethinking religious sects. These nonconformist communities rejected hierarchy and political order in favour of creating a more equitable society. Author, religious scholar and historian Christopher Zeichmann offers an alternative lens...

Why yellow traffic lights were designed to be ambiguous 20.05.2026

The yellow traffic light is a perfect example of imperfection — with intention. While driving you have to think fast. Do you speed up or stop, whether that means easily or slamming on the brakes? Every driver has their answer and what lies in the middle is a vast perceptual field. A great deal of thought has gone into the engineering of the ambiguous yellow light, as IDEAS producer Seán Foley foun...

What North Korea’s personality cult has to do with Jesus 19.05.2026

He championed a radical dream — a 'United States of Africa' 15.05.2026

Africa is a centre of world history — a fact that's been deliberately obscured, says journalist Howard W. French.

Howard W. French delivered the Black History Month l...

The origins of celebrity, from medieval divas to Kris Jenner 14.05.2026

From Joan of Arc to Kim Kardashian, and Davy Crockett to Donald Trump, celebrity culture has deep and wide roots. Famous people who elicited Kardashian-level feelings of love and hate in the public were present centuries ago — long before screens and social media. Though, as we find out in this podcast, they all share similar qualities. *This episode originally aired on June 30, 2022. Irina Dumitr...

Believe it or not, romance novels are more popular than ever 13.05.2026

Heated Rivalry , Love is Blind or Boyfriend on Demand all underline the global appetite for passionate swooning. But let’s not forget the source for all of it: the romance novel.

The books and readership continue to evolve as popularity increases. What is i...

Pt 2 | What the River Wants to Be 11.05.2026

For thousands of years, estuaries were central to Indigenous agriculture on the West Coast. Then, when colonists arrived, they diked many of these ecosystems to create western farmland. Now, Cowichan Tribes is working with a group of scientists and conservationists to restore an estuary as an ecosystem and a food system — and the project has sparked an unexpected controversy. At the heart of the d...

Can abolishing all political parties topple fascism? 08.05.2026

Simone Weil had a radical solution to end fascism that surged through Europe in the aftermath of the First World War: abolish political parties. She argued political parties were not democratic, they were dangerous. IDEAS producer Nicola Luksic explores the French philosopher's enduring insights to help us better understand the current political climate. *This episode originally aired on Oct. 20,...

How to measure 'prosperity' 07.05.2026

It's safe to say right now the majority of us are feeling the pinch. Grocery and fuel prices are on the rise and the income gap between the wealthy, and everyone else, continues to grow. And yet, aside from the U.S., Canada is the strongest economy of the G7. A prosperous country doesn't necessarily translate to a fuller wallet for its citizens. Host Nahlah Ayed and panelists discuss how 'prosperi...
