If you think you've never heard Jerry Granelli play drums — you likely have. Think of a comic strip holiday special and an iconic soundtrack: A Charlie Brown Christmas. Jerry was 22 years old when he became a member of the Vince Guaraldi Trio, the jazz band behind the popular 1965 album. His long career was legendary, accompanying many of the greats like Mose Alison, Sly Stone and The Grateful Dead. Producer Mary Lynk was lucky to meet with Jerry on the eve of his 80th birthday for a wide-ranging conversation. The gifted composer and jazz giant died in Halifax in 2021. *This episode originally aired on December 21, 2020.

Handel’s Messiah is one of the best-loved pieces of Christmas music. Only it was meant for Easter. But it draws on far more from the Old Testament than the New. There are more surprising facts about this 18th-century masterpiece that IDEAS explores with Ivars Taurins, founding director of the Tafelmusik Chamber Choir who has conducted Messiah over 200 times, and veteran CBC Radio broadcaster Robert Harris. In nine movements, they reveal the hidden treasures of Handel’s celebrated work. *This episode originally aired in 2015.

The nativity story that Christians believe is that God took the form of a baby named Jesus who was born to save the world and bring about an enduring peace. So what happened? Did we miss it? And what happens next? These are questions Trappist monk Thomas Merton grappled with in his own meditation on the Christmas story. His version "The Time of The End is the Time of No Room" was published in 1966. At the time he called it a sober statement about the climate of our time, a time of finality and fulfillment.

In an era of political polarization and fatigue from ongoing crises, hope is critical. But it's not something you have; it's something you do, argues education scholar Kari Grain. "Critical hope" in action is not just the belief that transformation is possible — it's necessary. In her book, she explores seven principles for practicing hope that confront toxic positivity, social injustices, and gives anger and grief a seat at the table.Kari Grain is a professor at the University of British Columbia in the Faculty of Education, where she leads the Masters program in Adult Learning and Global Change Program. She delivered the University of Prince Edward Island’s 2025 Shannon K Murray Lecture on Hope and the Academy.

Indigenous math isn't just about numbers and equations, it involves culture, spirituality and more. Math professor Edward Doolittle, a Mohawk from Six Nations in Ontario, sees math as something embedded in Creation itself. In his Hagey Lecture at the University of Waterloo, he describes Indigenous mathematics as being grounded in cognition, emotion, the physical world and community. Indigenizing math, Doolittle hopes, will make it more approachable and meaningful to Indigenous students — show them how entwined it is with everyday life and something much bigger than ourselves.

"We are the monsters" — that's the premise for the genre of film known as body horror — movies that fixate on monstrous and grotesque changes to the body. There have been good body horror films and bad ones, but "The Fly" starring Jeff Goldblum and Geena Davis was perhaps the most consequential. The movie captured anxieties around bodily autonomy and physical decay, just as the AIDS epidemic was becoming catastrophic. Forty years later, Body Horror is back with films like "The Substance" and "Together." Producer Matthew Lazin-Ryder examines what these films reveal about our bodies, our minds and our sense of who we are.

In 2024, 'polarization' was Merriam-Webster's word of the year. That division still grows, making it increasingly difficult to connect to one another. But there are people having important conversations and they have advice for us all. From fighting for LGBTQ+ rights in Colombia, championing human rights in Southern Africa and working for a two-state solution post Oct. 7, the winners of the The Global Centre for Pluralism awards tell host Nahlah Ayed about how minds can and do change, and why we need to not only talk, but listen.

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 found out. He had his own encounter with what he was sure was the shortest yellow light in the world. It resulted in a traffic fine, and gave voice to so many questions.

Tech billionaires are on a mission to make the stories of science fiction a reality: space colonization, human/machine bio organisms, and living forever in a state of unhindered bliss. This version of a far future utopia may come of as a "billionaire boys and their toys" but experts warn such a dismissive attitude is naïve and dangerous. *This episode originally aired on Jan. 22, 2025.

This isn't a wrap or best of 2025 kind of list. This IDEAS podcast is packed full of all kinds of recommendations from our smart, insightful contributors. We asked them to suggest a work of nonfiction that recently made them think — maybe even think differently — about a particular topic. Their answers cover several genres and varied subjects. Some may surprise you.Don't worry about writing any titles or names down, we have that covered on our website. The online list also includes a bonus: added recommendations from IDEAS producers. Enjoy!

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.Marcello Di Cintio's book is called Precarious: The Lives of Migrant Workers.

Growing up with food insecurity, Julian Napoleon yearned to be a farmer. His great-grandparents once farmed on the Saulteau First Nations reserve in northeastern B.C. Over the decades, the farm was replaced by the bush, and the ideas of communal, seasonal living started to fade away. Five years ago, Julian moved to Amisk Farm to bring it back to life. This year the farm has produced food for over 300 Indigenous households, free of cost.IDEAS visits Amisk Farm to learn about rural food security, Indigenous food sovereignty, farming in the north, and what it means to come home and grow a new home in a radically transformed landscape. 

There’s a constant mantra Frank Gehry would always hear from his mentors who have since died – “Don’t you dare ever stop working.” It’s a sentiment he lived by right until his death at 96. In fact his last major cultural building, the Guggenheim Abu Dhabi, will open in 2026. So how does his fierce, creative drive square with his mortality?In an expansive conversation from 2017 with IDEAS producer Mary Lynk, Gehry shares his thoughts about death and his life, from growing up Jewish in Toronto, to his complicated relationship with his father, to his move to L.A. at 18, to how his career flourished. *This is the second episode in a two-part series.Listen to Part One: The architecture that brought Frank Gehry to tears

Rebel architect Frank Gehry believed architecture IS art. He strived to evoke emotion in every design. Last Friday, Gehry died at 96 but he never stopped creating. In 2017, IDEAS producer Mary Lynk had a rare opportunity to spend two days with Gehry at his LA studio. Their wide-ranging conversation covers many aspects of his life and career, including a moment at 40 when the sight of an ancient piece of art from 500 BC led him to weep. "I think if you went and looked at it, you would cry too," he told Lynk.*This conversation is a two-part series that delves into Frank Gehry's infusion of humanity into his designs.Listen to Part Two: Architect Frank Gehry on how to exit life

Sometimes the universe hands us a gift. Over the past year, our podcast listeners spent a total of 526,915 hours listening to our program. 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. To give you a hint on some of the picks, on the bad list: online identity management. Trickle down economics. On the good: Free Trade. Girl Bosses. Apparently open borders is still an open question.Panelists Jamie Liew, a University of Ottawa law professor and novelist; University of Toronto philosopher, Joseph Heath; and the Canadian Shield Institute’s, Vass Bednar, joined IDEAS producer Mary Lynk on stage, in front of a live audience at the Isabel Bader Theatre for this episode — the last in our special series celebrating our 60th anniversary.Listen to more episodes:The time when a guest said, "I love you!"How an IDEAS episode on traffic changed a doctor's practiceCBC Massey Lecturers reveal how the talks changed themHow IDEAS saved a listener from sending a regrettable email

"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 that.”And we're grateful to hear from Cathy and other listeners who share their personal encounters on how IDEAS shows up for them, as we continue our 60th anniversary series. *This is the fourth episode in our special programming.

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 story sustains him after the loss of his wife. Also in this podcast, we find out how IDEAS inspires everything from sonnets, to art, and to recreating historic feasts. *This is the second episode in our 60th anniversary series.

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 part of a week-long celebration to mark our 60th anniversary. IDEAS is giving the mic to listeners like Oda to share their stories on how our program led to life-altering moments. *This is the first episode in our special programming marking our 60th anniversary.Listen to other episodes in this series:The time when a guest said, "I love you!"CBC Massey Lecturers reveal how the talks changed themHow IDEAS saved a listener from sending a regrettable emailThe best — and worst — ideas of the last six decades

For Afghans, listening to a traditional song can bring them back "home." In 2021, when the Taliban seized power again in Afghanistan, orchestras disbanded and musicians fled for their lives. They brought with them their distinctive and storied music, embedded with notes hailing from classical music from Iran and India. IDEAS takes a journey to Afghanistan with members of the Afghan diaspora, and asks how the idea of home is encapsulated in music and how conflict has played a role in reshaping Afghan music.*This is the final episode in a five-part series called The Idea of Home exploring the multiple and contested meanings of home. This episode originally aired on June 16, 2022.Guests in this episode:Mir Mahdavi is a poet, a writer, and a researcher in the area of art, literature and poetry, originally from Afghanistan.
