Cocaine in waterways makes salmon roam further, and more…

Cocaine and many other chemicals and drugs are found in many waterways, but especially around wastewater treatment plants. Scientists exposed wild juvenile Atlantic salmon to cocaine and its byproduct to see how it impacted their behaviour in the wild. As a result, the fish swam twice as far, which could put them in more danger.

Your tomatoes have a backstory and it’s not always pretty

In fact, author and journalist Marcello Di Cintio argues Canadians are complicit. After four years investigating the lives of migrant workers, he found that many temporary foreign workers are trapped working in precarious, exploitative conditions. These jobs are essential to our economy and society, yet invisible. Each migrant worker has a story to tell, says Di Cintio. He joined IDEAS host Nahlah Ayed on a visit through the tomato capital of Canada to hear their stories and talk about what his investigation reveals about Canada. *This episode originally aired on Dec. 11, 2025. Marcello Di Cintio's book is called Precarious: The Lives of Migrant Workers.

What will Canada do about prediction markets?

Betting on a future event — like, who will be a bridesmaid at Taylor Swift's wedding — is the whole point of prediction markets. Every year, Americans spend billions on these kind of bets, but Canada hasn't fully opened the door to them. So, should we let this type of trading in, put restrictions on it, or just say no? Also, what's old is new again as more Canadians take up film photography. And we find out how Nike lost its cool factor.

How port cities like Singapore shaped the world

Port cities are where worlds collide. They are a place of cultural, economic, political and religious contact. They've existed for millennia and facilitated the birth of empires and the rise of a globalized economy. Without port cities, our world would look very different. In the first episode of our series on how port cities shaped the world as we know it, UBC journalism professor Kamal Al-Solaylee visits Singapore — a constantly-evolving port city whose maritime roots go back to the 13th century.

Could the Dust Bowl of the 30s happen again?

The Dirty Thirties might seem like the distant past but according to IDEAS contributor and professor Evan Fraser now is the time to heed the lessons about what worked to save farmers and agriculture.

But Fraser adds it also serves as a guide to solutions that could help us muddle through as the world lurches into another chapter of environmental, political and economic upheaval. Guests in this episode: Evan Fraser is a geography professor and director of Arrell Food Institute at the University of Guelph. Pamela Riney-Kehrberg is a distinguished professor of history at Iowa State University. Robert McLeman is a professor of geography and environmental studies at Wilfrid Laurier University.

The 'shocking betrayal' of widespread antisemitism

Marsha Lederman is a child of Holocaust survivors. She lives with the fear that one day someone will take her and her son like the Nazis did with her parents and their parents. "This is ludicrous," she told herself many times. But then she saw how people celebrated the October 7th attacks and watched how antisemitism showed up in the circles she felt most at home. This spring to mark Holocaust Memorial Day, Lederman and child Holocaust survivor Jeanette Goldman shared their stories on Zoom at the University of Toronto's Regis College — an online event due to security reasons. They spoke about what true solidarity means today as antisemitism continues to rise in Canada. Lederman says: "We cannot allow antisemitism to stop us from speaking about antisemitism of all things." Guests in this episode: Jeanette Goldman is a retired federal judge and a child Holocaust survivor. Marsha Lederman is a journalist, daughter of Holocaust survivors, and author of Kiss the Red Stairs: The Holocaust Once Removed, and October 7th: Finding the Humanitarian Middle. Mary Jo Leddy is a Catholic theologian, author, activist, and founder of Romero House in Toronto. Bertha Yetman is a Regis College Alumnus, and organizer of “Remembering the Holocaust.”
