Your World Tonight - Mark Carney's "Canada Strong" pitch, Studying ADHD in women, Keeping campus radio stations alive, and more

Episode Date: April 19, 2026

Mark Carney is doubling down on his “Canada Strong” message ahead of a key trade review deadline. In an address posted on YouTube, the prime minister vows to diversify the economy, and protect Canada’s future -- no matter the political climate. And who he quotes might provide the biggest clues of all.Also: Nearly two million Canadians are believed to have ADHD. But the diagnosis is highly gendered.Boys and men are not only more likely to get a diagnosis, but it's often discovered much earlier.That's why researchers at the University of Calgary are looking for hundreds of women and girls to study how ADHD affects them throughout their lives.And: They're the voice of students across the country. But many of Canada's campus radio stations are at risk of going silent. The student unions who fund them say radio is outdated, lost in the noise of social media. However, there is a renewed push to see an on-campus radio resurgence. Plus: U.S. and Iran prepare for a new round of peace talks, Mass shooting kills eight children in Louisiana, Preserving Ukraine's cultural heritage, and more.

Another signal the Prime Minister is trying to turn the tide on Canada-U.S. relations. Mark Carney's speech sets the stage and strikes the tone ahead of a major trade review. And who he quotes might provide the biggest clue of all. This is Your World Tonight. I'm Tanya Fletcher, also on the podcast. Another round of war negotiations is on the horizon.

Donald Trump says the U.S. is sending a team, but will be there. the Iranians be there? That's still an open question. And radio is live, radio is local, radio is immediate, and I think those are really important things. The campus radio station. Many have faded away from Canadian institutions drowned out by the noise of social media, but now a growing student call for an on-campus radio resurgence. We begin tonight in Ottawa. Mark Carney is doubling down on his Canada strong message ahead of a key trade review deadline. In an address posted to YouTube, the Prime Minister vows to diversify the economy and protect Canada's future no matter the political climate. The CBC's JPM Tasker breaks it down.

The U.S. has changed and we must respond. Canada-U.S. trade tensions are heating up again with the Kusma Review deadline fast approaching. Prime Minister Mark Carney now warning the country should prepare for some turbulence ahead. Many of our former strengths, based on our close ties to America, have become our weaknesses, weaknesses that we must correct. In a new government-produce video, Carney is renewing his commitment to urgently diversify away from the states

amid mounting political turmoil south of the border. We can't bet our future on the hope that it will suddenly stop. Carney is also relaying for the first time that he draws inspiration from Sir Isaac Brock, A war of 1812 hero who died defending what is now Canada during that American invasion. This statue of General Brock that I see every morning in the Prime Minister's office reminds me that when we're united as Canadians, we can withstand anything. We wouldn't have a country without Brock. Historian Arthur Milne says invoking a figure like Brock is steeped in symbolism, a reminder that the country has beat the Americans before, despite long odds.

Canada can triumph. The Canada can succeed, but above all else, the Canada's worth fighting for. Carney's national pep talk comes as the Americans ramp up the rhetoric against Canada, including from the likes of U.S. Commerce Secretary Howard Lutnik. They suck. Look, we are a $30 trillion economy, right? We are the consumer of the world. Okay. Carney has a problem with us. While the U.S. and Mexico have held a series of meetings, there have been formal talks with Canada in recent months about renewing the trilateral agreement. We need a tariff-free deal. We need to get these obstacles out of the way.

Conservative leader Pierre Polyev, meanwhile, is urging Carney to patch things up with the Trump administration, saying the country's economic future depends on it. He's wrong to suggest that we can have a permanent rupture with our biggest customer. While taking inspiration from a wartime general who battled the Americans, the Prime Minister is still trying to bring about peace on the trade front. His point person on Canada-U.S. Relations, Minister Dominic de Blanc, says conversations with the Americans are happening behind the scenes. Telling MPs late last week, it's been a challenge coming to an agreement that works for both sides. Still, he calls it an immense priority for the government.

J.P. Tasker, CBC News, Ottawa. Turning to the war now, the U.S. wants to talk. President Donald Trump says he's sending a delegation to Pakistan for another round of peace talks with Iran, though it remains unclear if top Iranian officials will attend. It all comes as Trump again threatens to destroy Iran's civilian infrastructure. Our Katie Simpson has the latest from Washington. Vehicles are stopped at checkpoints as part of a security lockdown in Islamabad. Final preparations for another possible round of peace talks between the U.S. and Iran. President Donald Trump announcing on social media that an American delegation will travel to Pakistan Monday night.

The White House says the team will be led by Vice President J.D. Vance. The outcome of these talks will be incredibly consequential, and as the president is stated, he is prepared to escalate to de-escalate. The U.S. ambassador to the U.N., Mike Walz, urged Iran to agree to American demands in these peace talks. However, Tehran is not confirming it will participate. Hours after Trump announced the American delegation, Iranian State TV reported the regime would be absent, citing unrealistic American expectations

and the ongoing U.S. blockade of Iranian ports. Trump says the U.S. took custody of an Iranian vessel that tried to evade the American blockade, saying the cargo ship refused to stop so the U.S. Navy blew a hole through the engine room. Traffic through the Strait of Hormuz remains at a standstill. In response to the U.S. blockade, Iran is not allowing any ships to pass, firing shots at two other vessels over the weekend.

They got a little cute as they have been doing for 47 years. Nobody ever took them on. We took them on. President Trump accused Iran of violating the ceasefire and again demanded Iran make a deal. Or else, he says, the U.S. would knock out every single power plant and bridge. No more Mr. Nice Guy, he wrote on social media. Trump has repeatedly threatened to target civilians. infrastructure, with members of his administration, including Ambassador Walts, rejecting

arguments, that kind of action amounts to war crimes. And by the way, bridges, power plants that are run by the IRGC, which runs the entire military, are absolute legitimate military targets. While there is confusion over another round of peace talks, Americans are being warned to brace for higher fuel prices for months to come. Energy Secretary Chris Wright says it will take some time. before gas prices go back down to where they were before the war started. That could happen later this year. That might not happen until next year.

But prices have likely peaked and they'll start going down. The longer gas prices remain elevated, the more of a problem it becomes for Trump and Republicans heading into the midterm elections this fall. If voters are angry, Republicans could lose control of Congress, making it much harder for Trump to implement his agenda. Katie Simpson, CBC News, Washington. Meanwhile, in the occupied West Bank. Israel's defense minister says the country's main goal in Lebanon is to disarm Hezbollah.

His remarks come as Israel's military published a map of its new deployment line inside Lebanon, bringing dozens of mostly abandoned villages under its control. A 10-day ceasefire between Israel and Lebanon is holding, though there have been attacks, including one that killed a French peacekeeper on Saturday. The French president blames Hezbollah, but the Iran-backed militants deny any involvement. To Louisiana now, stateside, a gunman has killed eight children in a mass shooting in Shreveport. Steve Futterman has those details. Police say this was part of a domestic dispute. Beyond that, they are not giving details about a specific motive.

Authorities were first alerted at around 6 o'clock in the morning. When they arrived, they found the victims at two locations. Eight children between the ages of 1 and 14 were killed. Two women were seriously wounded. One of them reportedly had a relationship with the gunman. Tampa Taylor is a Shreveport Councilwoman. There are eight children that are deceased. I can't be strong for you.

I think about the mother and what this family has lost. I think about this community and what this community has lost. And I don't have the words to give you, and I'm sorry. The gunman was shot and killed by police during a chase. Police say the suspect was related to some of the children. Steve Fetterman, CBC News, Los Angeles. Still ahead, many women struggle with symptoms of ADHD, but they often go undiagnosed or it's mistaken for something else.

Now researchers at the University of Calgary are trying to get to the bottom of that by figuring out how the disorder affects women throughout their lives. That's later on your world tonight. Falling rain and melting snow are inundating hundreds of homes in flood-prone communities across Ontario and Quebec. Some areas are seeing record high river levels, triggering evacuations and bridge closures, and rising waters are expected to threaten some vulnerable communities through the week.

The CBC's Philip Lee-Shanock reports. Residents of Gatno, Quebec, who live along the Ottawa River, had to decide whether to stay or go. This woman says she just managed to get out with her car. I don't think I'll come back, she says. Gatineau-Mare, Maude Marquis Bisonette, says dozens of roads remain closed and residents in more than 160 homes were at risk. We anticipate the water to come to touch the house,

so there could be infiltration inside of the house. So this is why it's very important for citizens to have sandbags ready and some pumps, of course. She says the Ottawa River is predicted to rise by 30 centimeters during the next 12 to 24 hours, when it will hopefully stabilize through the week. We expect the level of water to be quite high for the next two weeks.

At a flood-prone area west of Montreal, Quebec Premier Christine Fraschette says providing residents with sandbags and pumps will be part of yearly preparations. We are seeing that spring floods, unfortunately, are part of our reality because of the climate changes. We now see frequent episodes.

In Ontario, areas north and west of Toronto are already dealing with washed-out roads, bridge closures and rivers swollen beyond their banks. We now have lakefront property on the side of our house and the back of our house, which we do not normally have. Minden resident Tatra Palfrey said volunteers who piled sandbags helped save her 170-year-old home. So far in previous floods, we haven't flooded. This time it looks a little dangerous.

Not far away in Muscoca, Ontario, real estate agent Kelly Fallis says this is the fourth flood in the last decade. The water levels are right now 5.5 inches shy of the 2019 flood, which is the news nobody wants to hear. Mayor Kathleen Thorne Rochev, West Nipissing, declared a state of emergency. We've seen the waters of the Sturgeon River rise rapidly. The roads are completely covered with water sometimes up to about two feet of water. The worry now is that a rapid warm-up will melt the ice pack, a problem in a year with record-breaking snow. We're still in the middle of our thaw.

So there is still a lot of snow and water left in the bush north of us that we're still waiting to arrive. So we know that this is just the beginning. The good news is Environment Canada expects no significant rainfall and temperatures to remain below normal. Fultes-Shadok, CBC News, Toronto. Scientists are warning of the risks of one of the world's most popular fertilizers, urea. It's commonly used in Canadian agriculture

and, in fact, helps grow most food in this country. But a new study shows it is damaging the ecosystems of many freshwater bodies on the prairies. Alexander Silberman has that story. Ian McCreary is getting ready for spring planting on his farm near Bladworth, Saskatchewan. It's a bouncing act. The fertilizer going into his fields, vital to grow food and make a living. But if not carefully contained, risky to the environment. Nitrogen fertilizer is incredibly important and it's quite potentially dangerous.

So it needs to be managed. Urea, a popular fertilizer that helps feed most of the world. is now a source of concern. The product is threatening to degrade nearly half of freshwater sources on the prairies, according to a new study by researchers in Saskatchewan and Manitoba. From an environmental perspective, absolutely there's a problem. Peter Levitt is a biology professor at the University of Regina

and one of the authors of the report. We need to be really clear that this stuff cannot get into the water. The research team added the nitrogen fertilizer to farm ponds. They found algae growth took off. water turned green and soupy and oxygen was drained. Leavitt says the effects destroy the ecosystem, killing fish and wildlife. It's just a warning sign. The red flag is up now. We should pay attention to this. The study warns the threat to water quality is likely a global issue, with agricultural regions in the U.S. and China identified at risk. Other experts say the study

is strong and important, but caution Urea doesn't act alone. Ashtim Bissomis. is a professor of environmental sciences at the University of Guelph. We need to think about it is about how interacts with the existing phosphorus in the ecosystem. We don't want to scare people out. The researchers behind the study say telling farmers not to use the fertilizer at all is not a viable solution. Kill Gushelak is a biology professor at the University of Manitoba. Playing the balance of the need to grow food and the need to maintain water is a really big challenge that is global.

The goal for now is mitigating. finding ways to keep fertilizer in the fields and out of the water. It's really urgent. In southern Saskatchewan, McCreary leaves trees around wetlands as natural buffers. He also mapped his soil to see where fertilizer is not needed, trying to reduce what he puts in the ground. And this recent study said fresh water is another reason why it's really urgent to make it happen. McCreary says government support is needed to encourage farmers to adapt. Alexander Silberman, CBC News, Bladworth, Saskatchewan.

Nearly two million Canadians are believed to have ADHD, but the diagnosis is highly gendered. Boys and men are not only more likely to get diagnosed, but it's often discovered much earlier in them. That's why researchers at the University of Calgary are looking for hundreds of women and girls now to study how ADHD affects them throughout their lives. The CBC's Joe Horwood takes a look.

So I have a couple of different methods. After her friend was diagnosed with ADHD, Carly Irvin says she started to notice some similarities. The inability to kind of pick up on when to jump into conversations, which I did not realize not everybody had the issue with. A year and a few appointments later, Irvin had her answer, along with a treatment plan. It was very freeing to kind of be like, okay, maybe it's not just me needing to feel like I'm different than everyone, and it's a bad thing. Maybe it's a part of something I just need to understand.

And we know that women in their 30s and 40s are the group that's getting diagnosed at the highest rates right now. It's stories like Irvins that Emma Climie is collecting for her research at the University of Calgary. She's recruiting hundreds of Canadian women and girls with or without ADHD to take part in a study.

The oldest lady we have right now is 94. Comparing how the neurodevelopmental condition affects women throughout their lives. A baseline of knowledge, Canadian researchers don't have. Women's Health in general is understudied, but certainly with ADHD. Climie hopes the project can guide future research and physicians to help identify the condition earlier in life. Their kids are getting diagnosed and then they start to kind of say, oh, well, I was just like that as a kid and we're a lot of light.

Sarah Binder sits on the advisory board for the Canadian ADHD Research Alliance, or CADRA. She says while more women are tracking down a diagnosis, there's still a gap in understanding. what that means for the rest of their lives. For females with ADHD, the hormonal piece is absolutely crucial. A lot of women who have previously been undiagnosed with ADHD will have much more severe postpartum depression and anxiety. And then now we see a lot more women paying attention to the hormonal fluctuations of perimenopause. Like if I don't have them out somewhere, I'm going to forget about them.

For Irvin, medication and understanding her condition have helped. Managing her ADHD will be a lifelong task. Menopause is already a terrifying thing to have to go through. It's so much on your body to think it's going to get even worse with ADHD is mind-blowing. Cadra writes the guidelines for assessing and treating ADHD in Canada. Climie hopes her study can help inform those diagnostic regulations with a bigger focus on women and girls. Joe Horwood's CBC News, Calgary. In BC now, it has been nearly a year.

since a deadly attack on Vancouver's Lapu-Lapu festival shook the country. Today, Vancouver's Filipino community is gathering to remember, mourn, and honor those victims. They're calling it the Lapu-Lapu Day of Togetherness. RJ Aquino is the chair of Filipino, B.C., which organized the event. He says the day is not meant to be another festival, but is instead to focus on reflection, healing, and connection. One of the most powerful things that I've seen over the last, last year is when we've had these smaller type of gatherings, it really does, you know, activate

kind of that feeling of community. Bayaneehan is what we called it in Tagalog. And it really does make people feel like they're not alone and processing what's going on. 11 people were killed and dozens injured when an SUV rammed into a crowd of revelers at last year's festival. The man accused faces 11 murder charges and 31 counts. of attempted murder. The United States says Americans should reconsider traveling to Nigeria, and that large parts of the country should be avoided at all costs. The Canadian government has also issued similar travel advisories for Nigeria, but as freelance reporter Kunle-Babs tells us,

Nigerian officials say those warnings are inaccurate, exaggerated, and are bad for the country's emerge. The latest US travel advisory warns its citizens against visiting Nigeria, citing concerns over crime, terrorism, civil unrest, kidnapping and limited health services. Their advisory follows renewed violence, including a recent attack in Borneo state, northeast Nigeria, where militants overrun a military base killing a senior army commander and several soldiers. But for many Nigerians, the issue goes beyond safety to how the country is portrayed internationally and what that means for opportunity. Which foreign or investor will want to come into a country that is not safe? It's not good for our economy and it's not good for our image as a nation. It's not

everywhere that is dangerous, but the one in Mexico looks like if the whole country is unsafe. The U.S. State Department has maintained Nigeria at level three, which means reconsider travel, with 23 of the country's statistics states under the strata do not travel category. The U.S. Embassy in Abuja has also suspended visa appointments, though emergency services for American citizens remain available by appointment. It is unclear how long the suspension and closure will last. We usually host a lot of diplomats and expats at our lounge. Michael Immanuel, who manages a social lounge in Abuja says the impact is already been felt.

Since the advisory came out last week, business has been very slow. Most of our clients has been very cautious. Nigeria has been battling insecurity for more than a decade, while the threat remains real in parts of the country. Analysts say the way these risks are communicated can have wider implications beyond the immediate security concerns. While these advisories are based on security assessments, they can sometimes present a broad picture that does not reflect regional differences within a large country as Nigeria. based policy experts, Amzad Lawal, says why the concerns behind such advisories are valid, their broader impact can extend far beyond security, shaping how Nigerians perceive globally and influencing economic opportunities.

Perception plays a very important role in how countries attract investments and partnerships. When advisories are broad, they can create fears that goes beyond their actual risk and affect sectors that rely on trust and movement. The Nigerian government says the U.S. decision is a routine precaution that does not reflect the overall security situation across the country. It notes that the United States continues to support Nigerian military through training, intelligence sharing and security cooperation. As travel warnings shape global perception, Nigeria faces a broader challenge, balancing real security concerns with the need to protect its image and economic prospects. Kunlebabs for CBC News, Abuja, Nigeria. As Russia's war on Ukraine continues, Vladimir Putin is escalating attacks on another front,

systematically targeting Ukraine's cultural heritage, including churches and museums. His aim is to erase Ukraine's national identity. Freelance reporter Rob Cameron now on a Czech project that's trying to stop that from happening. The launch at Prague's National Museum of something called Arc 3, a mobile scanning van, destined to the frontline cities of Ukraine. They're like these witnesses of the mankind, of the history of all their knowledge and all the culture we have. Paul Safko, the 3D photography expert who is the creative brains behind the Ark 3 project. explained to me why it was so important to save Ukraine's cultural heritage.

Stories are very important, but sometimes you need something tangible to grasp, okay. I have heard about what happened, but this is an object which is directly connected to that. From the outside, Arc 3 looks like a regular van. Inside, however, is a sophisticated scanning system consisting of a robotic arm fitted with ultra-high resolution cameras. Well, I think the key message is once the war is over and Ukrainians will want to come back. Lubosz Wessili, head of the Karel Komarek family foundation

that's funding and directing the Ark project from Prague. Knowing that their cultural identity is saved and protected somewhere, even digitally, I think, can be a very strong element in their attitude towards coming back home and feeling like this is ours. And Ukraine's beleaguered cultural heritage workers are grateful for the help. Maxim Oostapenko, Director General of the National Kyiv-Pakh historical and cultural preserve, spent 14 months in the Ukrainian army. His institution is handling the Ukrainian side of the Ark 3 operation.

According to official data, around 1,500 sites of cultural and religious significance have already been destroyed or damaged by Russia. They include churches, libraries, theaters. Very often, the Russian target cultural sites directly. Their primary aim is to destroy all signs of Ukrainian national identity. Arc 3 is the latest permutation of an ongoing project, started by the foundation. Arc 1 was a truck-mounted container fitted with equipment to preserve and restore

valuable documents and manuscripts. Arc 3 is now setting its sights on preserving physical objects from Russia's war machine. For CBC, this is Rob Cameron in Prague. They are the voice of students across the country, but many of Canada's campus radio stations are at risk of going science.

The student unions who fund them say radio is outdated, lost in the noise of social media. But as the CBC's Peter Cowan tells us, there's a renewed push to see an on-campus radio resurgence. This is a CHMR top of the hour news break. For more than 50 years, students at Memorial University have shared their voices through CHMR, the school's radio station. Most of the station's funding comes from the undergraduate students' union, about $300,000 a year, money that's about to disappear. Nathan Gillingham is on the union executive. We're in very much a different media landscape these days, and that radio isn't really something that young people today are paying close attention to.

I've never personally listened to it. On the campus, some students see radio is something their parents listen to. Radio just feels like such an outdated term, where like podcasts is very much like a, like everyone has a podcast nowadays. But for Chimdama B. Damien, her time on air has changed who she is. to be a very shy person. But on joining the station, I've become better communicating. I've received so much support and encouragement.

It's not just CHMR. Last year, students at the University of Ottawa voted to defund the student-run CHUO. And you're tuned into Black on Black on CHU-OH9.1FM in Ottawa. Sarah Oyango was a volunteer host on the station for years. She says as people get more of their information from international tech giants like Meta and X, that local connection is being lost.

I've had people in the community tell me how they would tune in every Saturday on Black on Black to find out, you know, who died, who got married, who had children. If I could wave a magic wand and make campus radio extremely popular, I certainly would. Lori Beckstead is a professor at Toronto Metropolitan University in the Radio and Television Arts Department.

She got her start at Campus and Community Radio. She says there is hope as more people are starting to look for alternatives to big tech filled with AI content. Radio is live, radio is local, radio is immediate, and I think those are really important things that are to be lost for listening audiences. At Fansha College in London, Ontario,

cutbacks almost forced 106.9 TheX off the air. Now a local non-profit is taking over. Malvin Wright, with We Rise, says it's an opportunity to build something that goes beyond the campus. We wanted it to be community-based, and community-centered to really provide space for members of London's growing community. It's diverse community and it's very active and animated community. And back in St. John's, there is hope for CHMR.

Riel Rolman, the station's director, says it's clear people value what the station does. We're not going anywhere. We intend to keep going, to keep broadcasting. The way the community stood up for us was really moving, both the campus community and the wider community. Now they just need to figure out how to do it with a lot less money. Thank you so much for your support. Peter Cowan, CBC News, St. John's.

Finally tonight, some new music from a Canadian icon. That instantly recognizable voice of Celine Dion. She dropped this new single Friday, marking her latest step back into the spotlight. The romantic French ballad is called D'Ancant, meaning let's dance in English. The music video features scenes of couples' dance. dancing in the crowd all across the famous landmarks of Paris.

It marks her first French release in over a decade and her first original song in years. It also comes ahead of her recently announced return to the stage. Health problems had forced the cancellation of her last world tour in 2023, but now Dion is preparing to perform 16 shows in Paris in the fall. This has been your world tonight for Sunday, April 19th. I'm Tanya Fletcher. Good night.
