I worry about my kids. And if this vaccine could prevent or slow down, wouldn't that be amazing? The disease it's meant to guard against causes a painful rash on your skin. But new research suggests this common vaccine can also protect your your brain, the shingles vaccine and dementia. More data pointing towards a potential breakthrough and what that might mean for Canadians. Welcome to YOUR WORLD tonight. I'm Susan Bonner. It is Wednesday, December 3, just before 6pm Eastern. Also on the podcast, no, I said.
Mark Miller
What I said and I think I proved in my previous roles, you know, it's nice to talk but actions count and I think I've proved myself.
Susan Bonner
Standing by his words in both official languages. After weighing in on the debate over the decline of French Canada's new culture minister isn't backing down as Mark Miller's comments ignite controversy in Quebec.
Mark Miller
And we're in some pretty incredible, unprecedented times. And what I've been calling for is.
Susan Bonner
Stability, looking for stability and getting a political standoff. BC Conservatives say they've removed the party leader, but John Rustad says he's not going anywhere.
With millions of people around the world suffering from dementia, there is a global research push to develop ways to slow or prevent it. Tonight there's more hope in that effort and it's coming from a treatment used for something totally different. Jennifer Lagrassa explains.

Susan Bonner
I'm just staying the way I am by staying active, staying involved.
Jennifer Lagrassa
Pher is one of more than 700,000 Canadians estimated to be living with dementia.
Mo Ahri
We're extremely excited about this research.
Jennifer Lagrassa
In my group, Dr. Pascal Geldsetzer is the lead author of a new study out of whales. This latest research builds on other findings from Geltzer from earlier this year that showed a shingles vaccine can reduce the risk of getting dementia. Now, his research shows that the vaccine may slow progression of the disease and reduce the risk of dying from dementia.
Mark Miller
We're showing that there's not just benefits from shingles vaccination for dementia prevention, but.
Mo Ahri
That there also appear to be benefits among those who already have dementia.
Jennifer Lagrassa
The research looked at more than 300,000 people over nine years. In 2013, Wales rolled out a shingles vaccine. People younger than 79 were eligible, but anyone older wasn't. This cutoff gave researchers a unique chance to compare nearly two identical groups. One that was vaccinated and one that wasn't.
Mo Ahri
Preventing a disease is one thing.
Jennifer Lagrassa
Dr. Donald Weaver is a neurologist in Toronto.
Mo Ahri
But being able to actually therapeutically change its natural history, its course, is something completely different.
Jennifer Lagrassa
Shingles is a viral infection that causes a painful rash. The vaccine used in this study is the live version. It uses a weakened form of the virus. It's still unclear why this might offer protection, but there's some theories.
Mo Ahri
The vaccine just globally decreases inflammation in the brain and anything that decreases inflammation in the brain is going to have a therapeutic benefit and therefore decrease the likelihood of dementia.
Jennifer Lagrassa
The vaccine in this study isn't available in Canada, but the one on the market here is newer and more effective at keeping shingles at bay. And initial research on it has shown it may also lower the risk of dementia.
Susan Bonner
This study is so hopeful.
Jennifer Lagrassa
To me, all of this promising for people like Phayre who already got her shingles vaccine.
Susan Bonner
With my grandmother and my mother having it, now I have it. I worry about my kids. And if this vaccine could prevent or, you know, slow down, wouldn't that be amazing?
Jennifer Lagrassa
The next step for experts here, more research on the vaccine available in Canada to see if it could have the same far reaching effects. Jennifer Legrassa, CBC News, Toronto.
Susan Bonner
Canada's new culture minister started his tenure by diving into a delegate debate in his home province. Now Mark Miller is defending his stance on the status of the French language after backlash from Quebec's premier. Kate McKenna has the details from Ottawa.
Mark Miller
No, I said what I said and.
Kate McKenna
I think official Languages Minister Mark Miller isn't backing down.
Yesterday, on his first full day in his new job as minister, he said he was fed up with how the debate about the French language is often about identity and politics. He refused to say the French language is in decline in Quebec, saying only it is under threat and that it's weakened in North America. This foray into a deeply sensitive topic yielded a quick reaction in Quebec.
Premier Francois Legault called Miller a disgrace for all Quebecers and questioned how the new Canadian Culture Minister will be able to attend any Quebec events. There was also political reaction from the leader of the parti Quebecois, Paul St Pierre Plamondon, who said Miller has worked very hard against Quebec interests in other cabinet portfolios he's held, including immigration.
Mark Miller
It's nice to talk, but actions count.
Kate McKenna
And I think I've proved myself today, miller said. Legault's comments hurt, but he says he has supported moves to protect the French language made by the previous Trudeau government, which he was part of.
Mark Miller
I've been part of a government that recognized the clan of the French language across Canada and modified the law on official languages as a result, plus the 4 million dollar investment and send $800 million to Quebec for franchisation of new arrivals.
Kate McKenna
Miller is an Anglophone Montrealer, but he's fluent in both languages, having done most of his schooling in French. He raised his children to speak it as well. Colleagues, including Government house leader Stephen McKinnon, stood by him.
Mark Miller
I don't have a lot to say about that, But I think Mr. Legault.
Has some interesting opinions sometimes.
Kate McKenna
But the controversy followed him into question period again today.
With Conservative MP Pierre Paulus needling Miller over how it took one day in the job for his comments to get him in trouble.
Miller hit back, saying no one in Canada thinks Conservative leader Pierre Poliev will protect the French language. For now, the new minister says he's staying the course, even if it means starting his tenure in the middle of a political firestorm. Kate McKenna, CBC News, Ottawa.
Susan Bonner
An unprecedented leadership battle is shaping up in bc. The provincial Conservative Party says it has removed its leader, but John Rustad says he's not leaving. The CBC's Tanya Fletcher is following the turmoil in the province's official opposition. Tanya, what is the status of the party's leadership right now?
Tanya Fletcher
Well, Susan, it's still unclear. The B.C. conservative Party says John Rustad has been removed as leader, but John Rustad himself says not a chance. Now, this all started this morning. The BC Conservatives say around 20 MLA signed a letter saying they had lost confidence in Rustad and that an interim leader had been selected. Now, the statement goes on to say that the party had a majority of caucus inform legal counsel that they no longer supported Rustad and that triggered a caucus vote selecting an interim leader. Now, the party's board says it has certified Rustad as, quote, professionally incapacitated under section 1102 of its constitution and formally appointed Surrey White Rock MLA Trevor Helford in his place. Now, he spoke briefly this afternoon. Here's what he said.
Mark Miller
You know, we're in some pretty incredible, unprecedented times. And what I have been calling for is stability. And I think it's paramount that we get stability inside of our caucus. I think it's paramount that we get stability with our party. I think it's paramount that British Columbians get stability.
Tanya Fletcher
Not long after that, John Rustad himself responded quickly with a social media post saying, quote, I have not resigned, I have not been removed and I'm not going anywhere. He goes on to say a political party's board can throw around whatever creative of terminology they like. Professional incapacitation. Give me a break. Let me be clear. He says that's not a constitutional mechanism.
Susan Bonner
Tanya, what's at the heart of this? What are the MLAs angry about?
Tanya Fletcher
Essentially, it's ineffective leadership, both internally, you know, not being able to mend cracks within the party and keep multiple MLAs now from breaking off and going independent, but also externally not being able to capitalize on the groundswell of small C Conservative momentum since the last provincial election. You know, Rustad was first chosen leader of the B.C. conservatives in 2023 after he crossed the floors from the B.C. liberals and the party did relatively well. It rose to official opposition. But lately there have been disputes for months now and pressure has been mounting for him to step down as leader.
Susan Bonner
So what happens now?
Tanya Fletcher
Well, that's the big question. A lot of unknowns about legally what's transpired here as well, a lot of questions about this latest caucus vote Today. Were all BC Conservatives MLAs in the room?
Kate McKenna
A lot?
Tanya Fletcher
We still don't know. The section of the party constitution cited by the B Conservatives reads the leader can only be removed from office by resignation, death, incapacitation or the leadership review vote resulting in less than 50% support. Now they cite incapacitation. They added the word professional in front of that. So it's yet to be determined what is legally valid here and how much Rustad will choose to continue to fight this.
Susan Bonner
Thank you, Tanya.
Tanya Fletcher
You bet.
Susan Bonner
The CBC's Tanya Fletcher in Vancouver.
Coming right up. First there was nafta, then kuzma. Now officials are planning what's next for North American free trade and Somali immigrants in the United States prepare for a crackdown the day after Donald Trump called them garbage. Later, we'll have this story.
Alison Northcott
I'm Alison Northcott in Montreal where researchers are turning to music to help people communicate again after a stroke.
Later on your WORLD tonight. I'll tell you about a study looking to see if singing in a choir can help people regain their voices.
Susan Bonner
Three days of high stakes trade talk have started in Washington. Government officials and industry stakeholders from across North America are in the US Capitol for Kuzma hearings. The the trade agreement is up for review next year and there are concerns about its future given that President Donald Trump isn't respecting the current agreement. The CBC's Katie Simpson was at today's meetings. Katie, what did you hear?
Katie Simpson
It was largely pro Kuzma or USMCA as it's called down here. A lot of arguments in favor of keeping the agreement in place as it provides stability and predictability for industries and businesses. So for example, part of this afternoon, the hearings focused on agriculture and there were representatives for all kinds of American farmers and grain producers. Have a listen to Dennis Nuxalt. He represents Western US Growers who farm produce.
Mark Miller
We believe that the USMCA should be renewed. That tariff free access between all three of our countries for produce is vital for American growers, Canadian growers, Mexican growers, and then consumers across North America. But we also believe that this review is an opportunity to look at the trade between our three countries in produce and try to make some improvements on the improvement angle.
Katie Simpson
A theme emerged. Several witnesses spoke about challenges when it came to Mexico, specifically complaints about how the low cost of Mexican labor, how in certain states cheap Mexican produce can undercut American products. One blueberry producer put it this way. He said the good partner is Canada. And when it comes to Mexico, we have a partner we need to work on. It's important to remember that these hearings.
Alison Northcott
Are a really big deal.
Katie Simpson
The testimony could help shape decisions made by the Trump administration when the formal review process begins next June.
Susan Bonner
And Katie, that formal review process, people are braced, expecting it to be difficult.
Katie Simpson
Yet Donald Trump frequently complains about trade with both Canada and Mexico and he wants concessions from both countries. The review set for June initially was seen as a procedural kind of thing. But with Trump signaling he wants change, it is expected to be a very intensive negotiation process. In the Oval Office today, Trump was asked about what he expects.
Mark Miller
We're, you know, that's just an ongoing thing. It expires in about a year and we'll either let it expire or we'll maybe work out another deal with Mexico and Canada. But.
Look, Mexico and Canada have taken advantage of the United States like just about every other country. In all fairness, it's not them. I'm not blaming them.
Katie Simpson
Now, Trump has previously floated the idea of leaving Kuzma or coming up with some new kind of agreement, though he's not really gotten into any sort of specifics. That clip might scare a lot of people. That's not the first time he's said something like that. He has frequently and casually said things like that in the past. But based on the testimony we heard today, that is something many American businesses and industry leaders, they don't want to have to deal with that kind of uncertainty.
Susan Bonner
Katie, thank you.
Kate McKenna
Thanks.
Susan Bonner
The CBC's Katie Simpson in Washington. In Minnesota, people are bracing for more U.S. immigration agents to arrive in the state, specifically targeting its large Somali population. That follows Donald Trump telling immigrants from the African country to go back to where they came from. Katie Nicholson reports.
Mark Miller
This language has consequences.
Katie Nicholson
And community leaders lined up this morning in the Twin Cities to condemn the US President's language.
Mo Ahri
It emboldens extremists and it puts real people in danger.
Mark Miller
What is happening in Minnesota?
Katie Nicholson
Yesterday, US President Donald Trump unleashed a tirade against Somalis.
Mark Miller
Their country stinks and we don't want them in our country.
Katie Nicholson
And referenced a fraud scandal which he laid at their feet.
Mark Miller
Somalians ripped off that state for billions of dollars and they contribute nothing.
Katie Nicholson
It is true that nearly 80 Minnesotans have been charged in connection to a fraud investigation of a multi million dollar Covid era child hunger fund and that dozens of those charged are Somali, though most of them were US Citizens and the alleged ringleader is white. State Senator Omar Fateh says Trump is wrong, that his community contributes nothing.
Mark Miller
We know that our Somali community, we have teachers, we have business owners, we have politicians, we have folks that have.
Mo Ahri
Contributed immensely to our city, to our.
Mark Miller
State, to our nation.
Mo Ahri
Not only are his words hurtful, but.
Mark Miller
It'S just flat out wrong.
Katie Nicholson
Trump also debased Somalia as a country, calling it garbage.
Mark Miller
With Somalia, which is barely a country, you know they have no anything run around killing each other.
Katie Nicholson
On the streets of Mogadishu, Somalis condemned those remarks.
Somali individuals in America hold significant dignity within their communities, says Abdisalana Ahmed. And his remarks were a grave mistake.
These remarks come as multiple agencies are reporting renewed ICE operations targeting Somali communities in Minnesota.
Mark Miller
And by the way, there are more than 80,000 Somali people living in Minnesota. Almost all of them are both documented and citizens.
Katie Nicholson
Minneapolis Mayor Jacob Fry spoke out against the plans.
Mark Miller
Targeting Somali people means that due process will be violated, mistakes will be made. And let's be clear, it means that American citizens will be detained for no other reason than the fact that they look like they are Somali.
Katie Nicholson
The new ICE influx getting a frosty reception. Minneapolis police chief reminded the public his force won't help in any federal immigration crackdown, while Minnesota Governor Tim Walls called the action a PR stunt. Katie Nicholson, CBC News, Washington.
Susan Bonner
Foreign Affairs Minister Anita Annan says Ottawa is not involved in the sale of Canadian made armoured vehicles to the immigration agency. Washington is ordering 20 armored vehicles from a company based in Brampton, Ontario, as part of its crackdown on immigrants in the U.S. the contract with Rochelle is worth $10 million to be delivered within 30 days. Anand was asked if the federal government needs to approve the deal first. At this time, the government is not involved in the transaction.
Alison Northcott
We have not received any questions or permit requests regarding this transaction and I will continue to reiterate that Canada and the United States have a strong bilateral.
Susan Bonner
Relationship with an open line of communication in which, if necessary, I will raise the issues with Secretary Rubio. Anand made the comments at the NATO foreign ministers meeting in Brussels. She also said Canada has pledged another $200 million for military gear for Ukraine and 35 million in non lethal a It's part of an international effort to share the burden in equipping Ukraine after the US said it would reduce its commitment. Canada has now promised more than $800 million. A nor' Easter is bringing heavy snow, rain and strong winds to much of the Atlantic region. The storm knocked out power to thousands of homes and businesses, impacted travel and many schools were closed for the day. The center of the storm skirted along the coast of Nova Scotia and now headed for Newfoundland's east coast. The federal government's major projects plan is more than just a pipeline. There's also port expansion in Contrecoeur, near Montreal. But a proposal to invest billions of dollars on the international shipping terminal is getting local pushback and has experts wondering if it is the right move. Eli Glassner explains.
Mo Ahri
Afternoon at the Port of Montreal as shipping containers are picked up and sorted like children's toy blocks. The port handles 2,500 trucks per day, 80 trains a week and over 2,000 ships per year. Julie Gascoigne is a Montrealer who fell in love with the industry. Now she's the port's CEO. But her port has a problem. She says it's reaching capacity.
Susan Bonner
If you increase by 6% the cargo that used to go to us, that.
Jennifer Lagrassa
Now goes to another destination.
Susan Bonner
This port's full.
Mo Ahri
It's full to create space. In September, Ottawa announced plans to fast track the expansion of a terminal in Contrecoeur, a project which Ottawa says will create thousands of jobs and generate tens of millions of dollars.
50 kilometers down the St. Lawrence river from Montreal, cranes are busy removing trees in Contrecoeur. Residents of the Quebec community say they're worried about their quality of life.
Susan Bonner
They moved here to be in a quiet and beautiful place. They did not move here to live.
Kate McKenna
In a port in an industrial zone for sure.
Mo Ahri
Ellen Reeves is a spokesperson for the citizens group for Kontokur. With an impact assessment report predicting an increase in truck traffic to as much as 1200 a day, she fears for her community's future.
Susan Bonner
It's dead. It will be dead. It's going to become a huge industrial zone and it's not going to be the beautiful little town on the St. Lawrence River.
Mo Ahri
But the Port of Montreal CEO says Contrecoeur makes sense.
Susan Bonner
You've got Highway 30, you've got the.
Jennifer Lagrassa
Railway that's already there, you've got the.
Susan Bonner
Power with of course, hydro. We secured all the power for the.
Jennifer Lagrassa
Terminal and you have access to huge amount of markets.
Mo Ahri
So that project should have taken place 20, 30 years ago. Maritime shipping expert Jean Paul Rodrigue says this expansion is too little, too late. Meanwhile, the position of Montreal became increasingly, you could say marginalized in terms of the big trade because the ships were getting bigger. He points out the trend in container shipping is towards so called megaships, far too large to travel and dock on the St. Lawrence. Rodriguez says the federal government should have put its money into expanding the deep water port in Quebec City. Instead, there was investment committed by one of the largest terminal operators in the world, which was HPH and the largest Canadian rail line, cn. But that plan was scuttled by the federal government in 2021. While the port of Montreal says the Contacre expansion is a better site because of its access to markets and transportation systems. Rodrigue worries as Canada increasingly pivots to trade with Asia, Montreal could be shut out of the larger ship traffic. It depends on. Eli Glassner, CBC News, Montreal.

Every year, tens of thousands of Canadians suffer strokes. For many survivors, the long term effects include a loss of their ability to speak. But a groundbreaking study in Montreal is using song to help patients recover their voice. Alison Northcott explains.
Alison Northcott
Singing together gives of this small choir a chance to use their voices.
The four singers sitting side by side behind music stands in a Montreal community center have all suffered strokes and developed a condition called aphasia, which affects their ability to speak.
They're here as part of a study to see if singing together can help their recovery.
Edith Durand is a speech language pathology professor at the University de Quebec Artois Riviere and one of the researchers.
Susan Bonner
We are hoping that this study will demonstrate that choir activity is really good for people, good for their language, but good for their social relations too.
Alison Northcott
Durand says aphasia often comes with a drop in social participation because it's hard to communicate with friends and loved ones. The randomized controlled trial has sites in Montreal, Ottawa, Toronto and Tampa Bay, Florida. It's part of the Toronto based initiative SingWell, a network of researchers studying group singing.
Serge Balancique has had trouble writing and finding his words since his stroke in 2022. The 81 year old scientist and former professor hopes this study leads to more treatment options.
Mark Miller
I write because it gives me occasion to speak.
And to find my old voice.
Alison Northcott
It will take time to go through the data collected and see if it helps improve participants language skills and quality of life. Previous research suggests music may help leverage the part of the brain not damaged by a stroke to improve communication. But stroke neurologist Alexander Thiel says the available evidence is limited and more studies like this one are needed.
Mark Miller
There is definitely evidence that these kind of therapies can work. Doing this in this broader choir like context, in the social context is something, something new and we will have to see how.
These trials will end up.
Alison Northcott
The choir's vocal director, Jennifer Young Mi Lee says participants get something out of it regardless when they start singing. You could just see the soul free up.
Balancique says it's been a positive experience for him and he hopes the study can help others with his condition in the future. Alison Northcott, CBC News, Montreal.
Susan Bonner
We end tonight with a party animal ransacking a liquor store outside of Richmond, Virginia, then passing out on the bathroom floor.
Mark Miller
My officer came in and told me I pretty much apprehended a suspect. I was like fantastic. What happened?
Susan Bonner
Jeffrey Parker says the call came in last Saturday morning after an employee showed up for work to find the store had been broken into, bottles smashed on the floor, the suspect sleeping right beside the toilet. Parker was called because he's Hanover County's chief of animal Protection. The drunk as a skunk suspect was actually a raccoon that snuck into the store through the ceiling, found face down on the floor. Some call them trash pandas. This one was trashed, described by the responding officer as very intoxicated.
Mark Miller
You can't make this stuff up it happens. And I actually gave him officer high five. I was like, fantastic. I wish we had little handcuffs to put on him, you know?
Susan Bonner
It's believed the raccoon sampled a little too much from some of the spirits spilled on the floor. Whiskey appeared to be the drink of choice. The animal was taken to a local shelter to sleep it off. Barker says the raccoon was not injured, maybe a headache. And after sobering up, it was released back into the wild. Thank you for joining us. This has been youn World Tonight for Wednesday, December 3rd. I'm Susan Boner. Talk to you again.
