Toronto Zoo warns of extinctions if Ontario mining bill becomes law

Liam Casey, The Canadian Press 5 minute read Friday, Oct. 10, 2025

TORONTO - Species could go extinct if Ontario passes a controversial mining bill that is set to transform its approach to endangered species and the environment, the Toronto Zoo warned the province.

Bill 5, the Protect Ontario by Unleashing our Economy Act, would strike a blow to the recovery of several species the institution has been trying to save, said Dolf DeJong, the zoo's CEO, at a committee hearing at Queen's Park on Thursday.

If and when the bill becomes law, DeJong wants the province to step up with funding so it can dramatically increase its biobank with Ontario species that could die off as a result of the legislation.

"We're concerned this act will result in the erosion of biodiversity and the loss of species at risk," DeJong said.

Alexander Zverev says lightning struck his flight to Paris for the French Open

The Associated Press 2 minute read Wednesday, Oct. 15, 2025

PARIS (AP) — German tennis player Alexander Zverev said Friday his plane was hit lightning on the way to Paris for the French Open and had to turn around, delaying his arrival for the clay-court Grand Slam tournament.

He wound up getting in at about 3 a.m.

“We were supposed to fly yesterday evening at 6:45 p.m., and we took off from Hamburg,” said Zverev, last year's runner-up at Roland-Garros and seeded No. 3 this year. “We got struck by lightning. We had to do an emergency landing back in Hamburg.”

By the time he got on a different flight, his journey resumed at 1 a.m.

Sirop d’érable, le trésor de Saint-Pierre-Jolys

L’incontournable Festival du Temps des sucres se prépare à revenir au village de Saint-Pierre-Jolys les 5 et 6 avril. Prenant place dans la Cabane à sucre, une extension du musée, les visiteurs pourront festoyer et célébrer ce fameux sirop local aux teintes ambrées.

Le temps se fait plus doux dans le village de Saint-Pierre-Jolys où les récoltes de sirop d’érable ont doucement commencé depuis la semaine du 17 mars.

En effet, des gelées la nuit combinées à des températures plus élevées le jour créent les conditions propices à la saison des récoltes. Ce type de météo permet d’exercer une pression à l’intérieur de l’arbre favorisant ensuite l’écoulement de “l’eau sucrée” comme aime l’appeler Roland Gagné, le gérant de la Cabane à sucre du village.

“Grâce à Mère Nature, l’eau remonte des racines jusqu’en haut de l’arbre. Ça permet de nettoyer les veines de l’érable et ensuite le liquide s’écoule.”

At the start of Premier Wab Kinew’s government’s mandate, it signalled it would work to get Manitoba to a net-zero electricity grid by 2035. With 99 per cent of the province’s electricity already emissions-free, it is a small, but important gap to bridge.

À Saint-Eustache, la compagnie Tritec Concrete se lance dans la commercialisation d’une technologie d’élimination des déchets organiques aux nombreux avantages.

Sur le terrain de la compagnie Tritec Concrete, aux abords de Saint-Eustache à l’ouest de Winnipeg, une machine d’une dizaine de mètres de haut se dresse à l’extérieur, derrière les hangars.

Il s’agit d’un prototype de Rapid Organic Converter (ROC). Celui-ci fonctionne en continu depuis 2016 et a vu le jour sous l’impulsion de Jamie Dufresne, propriétaire de Tritec Concrete, qui a travaillé pendant une bonne partie de sa carrière dans la recherche et le développement.

“Je cherchais un moyen de récupérer les déchets agricoles, que nous brûlions à l’époque, et de trouver un moyen de le granuler ou l’ensacher. Le système actuel consomme tout ce qui est organique.”

Quand le froid gèle la collecte de sang

Les intempéries hivernales ont parfois des impacts insoupçonnés. Alors que les déplacements ont été rendus difficiles à travers le pays, la Société canadienne du sang doit combler les pertes causées pour répondre à un besoin toujours plus important.

Le temps hivernal s’est montré quelque peu extrême le mois dernier. S’il n’est pas nécessairement évident de faire le lien entre les deux, et bien les aléas météorologiques ont un impact direct sur la collecte de sang au Manitoba et plus largement dans tout le pays.

Aujourd’hui, il faut savoir que, la branche manitobaine de la Société canadienne du sang (SCS), ne compte pas moins de 30 cliniques mobiles. Ces dernières se déplacent trois fois par semaine dans les communautés rurales de la province. Entre autres, Brandon, Portage la Prairie ou bien Selkirk.

Or les intempéries ont provoqué l’annulation de plusieurs centaines de rendez-vous, comme l’explique Rayna Porter, responsable du développement communautaire pour la SCS ici, à Winnipeg.

Slow fashion houses embrace made-to-order to reduce waste

Nicole Thompson, The Canadian Press 6 minute read Friday, Oct. 10, 2025

TORONTO - On occasion, fashion designer and clothier Katelyn Woodburn is accused of running a scam.

When a customer makes a purchase without reading the "about" section on her website or following her on social media, they might send an email a week or two later saying something like: "Where's my order? It hasn't even shipped yet? What's going on?" Woodburn recounted from her Vancouver studio.

"Which is a totally reasonable response," she added. Consumers are conditioned to expect instant gratification when it comes to clothes shopping, but that's not really how Woodburn does things.

"I'll say, 'Oh, your shirt is being cut out. We're going to sew it tomorrow.' I tell them the whole process of what's happening. And 100 per cent of the time, I get a response going, 'Oh my gosh, I didn't even realize. This is so cool, no rush at all.'"

They say laughter is the best medicine. Throw a little song-and-dance into the mix and you get Larry Saves the Canadian Healthcare System — an 11-part web microseries that humorously addresses Canada’s ailing medical system through music and satire.

Sara Kreindler, a professor of community health sciences at the University of Manitoba, spearheads the show, drawing from her extensive research.

“It’s about starting a conversation,” says writer-composer Kreindler, who has a PhD in social psychology. “Whether you’re a health-care provider or just someone curious about the system, I want viewers to come away feeling empowered to hold our elected leaders accountable for addressing the underlying issues.”

Through the character of Larry, played by Winnipeg actor Toby Hughes, viewers embark on a journey navigating the complexities of health-care policy.

Bringing dental care to kids in schools is helping take care of teeth neglected in the pandemic

Michael Casey, The Associated Press 6 minute read Wednesday, Oct. 15, 2025

CONCORD, N.H. (AP) — Tucked away inside the teachers lounge at a New Hampshire elementary school, Amber Warner was having her teeth checked out for the first time.

The 5-year-old sat back on what looked like a beach chair and wore a pair of dark sunglasses as certified public health dental hygienist Mary Davis surveyed Amber's teeth and then with a tiny syringe applied traditional dental sealants, which had the consistency of nail gel.

“Close down and bite your teeth together, bite down like you are biting down on a hot dog or a cheeseburger," Davis told Amber, to ensure the sealants were done properly. After that, Davis flossed all of the “popcorn and the chicken, pizza between your teeth.” The whole visit took 15 minutes.

“Look at you. You are a pro on your first dental visit. I am so proud of you,” Davis said to the kindergartener, who got up from the chair and was hugged by a teacher's assistant.

Some doctors sneak education into their online content to drown out misinformation

Nicole Thompson, The Canadian Press 5 minute read Friday, Oct. 10, 2025

TORONTO - When Dr. Siobhan Deshauer makes online videos, her primary goal is to demystify medicine. Her secondary goal?

"I call it 'smuggling in education,'" said the physician and YouTuber, who boasts nearly a million subscribers on the platform. "You're coming for this mystery and this excitement, but I'm smuggling in some topics that I think are really important and that I'm passionate about."

Some experts say one of the best ways to fight a rising tide of medical misinformation on social media is to drown it out with captivating content backed by science, and Deshauer, an Ontario-based internal medicine and rheumatology specialist, is among a growing cohort of doctors and researchers doing just that.

Take one of her medical mystery videos, for example. In it, Deshauer tells the story of a woman who had lead poisoning. Doctors took ages to figure out what was causing her symptoms, but ultimately realized they were a result of lead in the Ayurvedic supplements she was taking.

Hadfield urges Shatner to 'soak up' spaceflight

One Canadian spaceman to another, former astronaut Chris Hadfield is encouraging William Shatner to follow the wise words of Captain James T. Kirk as he braces himself for a real-life blastoff: "Boldly go."

Hadfield said he quoted the "Star Trek" star's iconic mantra in a note wishing him well on his voyage aboard Jeff Bezos' Blue Origin rocket ship on Wednesday.

The flight was originally planned for Tuesday but Blue Origin has announced it is being delayed 24 hours due to forecasted high winds.

Hadfield, a self-identified Trekkie who commanded the International Space Station, said he's thrilled that after decades of service in the fictional Spacefleet, the Quebec-raised actor will soon get to experience the final frontier for himself.

Shoal Lake 40 toasts clean water

Melissa Martin 6 minute read Wednesday, Sep. 15, 2021

SHOAL LAKE 40 FIRST NATION – As he raised his glass, Chief Vernon Redsky looked at the water and a memory came rushing back. It reminded him of when he was a kid, he said, and the water in Shoal Lake was crystal-clear like that, back when he and his friends would splash along the shore, drinking from the lake when they got thirsty.

So he thought about that as he clinked his glass against two others, and took a sip. A toast, to the first officially safe tap drinking water in Shoal Lake 40: on Wednesday, after 24 years, the Treaty Three First Nation’s boil water advisory officially ended.

“It’s surreal to be at this moment,” Redsky said at a ceremony to celebrate the achievement, as well as the opening of the community’s new school.

One day earlier, a government official in Kenora, Ont., had officially approved the latest test results from Shoal Lake 40’s new water treatment plant, which started pumping this summer. That night, Redsky couldn’t sleep; he called a former chief to talk about the long road they had travelled to get to this point.

City eyes bird-friendly buildings

Gabrielle Piché 3 minute read Thursday, Sep. 9, 2021

GLAZED windows and limits on lighting are options the City of Winnipeg is considering to save birds from flying into buildings.

Approximately 25 million birds die in Canada annually by colliding with windows, according to a study used as part of the city’s research into the problem.

“We’re losing our birds, especially our migratory birds, at a really fast rate,” said Kevin Fraser, a University of Manitoba associate professor who studies the species. “Light and windows are huge threats.”

Winnipeg is part of the Mississippi flyway, a major migration route for birds.

New show pits sand carvers against each other, Bay of Fundy tides

Alan Small 5 minute read Thursday, Sep. 9, 2021

A new CBC show aims to put the fun in the Bay of Fundy.

The series is Race Against the Tide, and it pits 10 teams of two sand sculptors from around the world against the one of the Earth’s most relentless of timers — the record-breaking tides of the Bay of Fundy, where Atlantic Ocean waves surge between New Brunswick and Nova Scotia.

The fast-paced show, hosted by comedian Shawn Majumder, debuts Thursday at 7 p.m. on CBC with its first two half-hour episodes kicking off a five-week run that combines the labour of packing pounds of sand for a base with the careful carving of grains of sand to create remarkable works of art.

The sculptures are temporary though. The teams are given six hours to create their works, but shortly after they are judged, the Bay of Fundy waves wash the works away.

Japanese garden an enduring cultural experience

Colleen Zacharias 7 minute read Saturday, Aug. 28, 2021

The Japanese Cultural Association of Manitoba, 180 McPhillips St., opened to the public in 1987. The centre offers a wide range of programs which are designed to promote and enhance the understanding of Japanese culture. The centre also serves as the site for a beautiful Japanese garden. Built by Yoshimaru Abe who was born in Japan in 1914 and came to Canada with his family in 1927, the garden is an enduring cultural experience.

Prior to building the garden at the centre, visitors to the Japanese Folklorama exhibit in 1971 and in the years following had the opportunity to see a Japanese garden recreated by Abe. Using moss, rocks, and pieces of wood, Abe recreated an authentic Japanese garden on a concrete arena floor.

A gardener is called niwashi in Japanese. Abe was the distinguished niwashi at the Japanese cultural centre’s garden into his 90’s and was followed by Sam Matsuo, who maintained the garden for 10 years. Both Abe and Matsuo were assisted by dedicated volunteers. Today the niwashi is Raymond Normandeau, who has been involved with the centre for several years as well as in the building of the garden at the Japanese Pavilion at Folklorama. Normandeau will oversee an expansion of the garden at the Japanese Cultural Association — which is slated to begin this fall.

Currently, there are two different areas to the garden. The front garden is a long narrow strip on the outside of the building that faces into a concrete parking lot. The inner garden is an enclosed garden accessed by a short bridge and tall wooden gate. “It is not a pure Japanese garden,” says Normandeau. “It is representative of a Japanese garden. We don’t have the stalwarts of Japanese gardens — bamboo, clipped azaleas, and the black pine which is one of the most popular pine species in a Japanese garden.” But many fine elements of Japanese garden design can indeed be found here.

Vanessa Ahing a été végétarienne pendant plus de quatre années. Par refus de l’industrie de la viande qui, à son avis, est cruelle et nuit à l’environnement. Pourtant, un bon steak lui manquait. Pour réconcilier conscience et palais, un choix nouveau s’imposait...

Un soir de septembre, 2013, Vanessa Ahing rentrait de la campagne, où elle avait abattu son premier chevreuil. Souvenir de l’enseignante de 31ans: “J’étais toute seule. J’avais suivi une formation de chasse pour femmes, organisée par la Manitoba Wildlife Foundation. Mon chevreuil, coupé en quarts, était dans un sac de hockey dans le coffre de ma Honda Civic. C’était mon premier animal. Je voulais vivre l’expérience complète de la chasse. Donc pas question pour moi d’aller chez un boucher. D’ailleurs, j’étais étudiante. Je n’avais pas le fric pour me payer un tel service.

“Je me demandais comment j’allais faire pour préparer cette viande. Je n’ai pas été élevée dans une famille de chasseurs, ou même de jardiniers. Mes parents n’étaient pas prêts à avoir un chevreuil chez eux. Et moi, je vivais dans un petit appartement pour célibataires au centre-ville de Winnipeg.

“Il était tard. Trop tard pour dépecer l’animal tout de suite. Alors, j’ai ouvert les fenêtres de mon appartement. Je me suis endormie dans mon sac de couchage. Le lendemain, j’ai tapé ‘Comment couper de la viande de chevreuil’ sur YouTube. Et je me suis mise à l’œuvre.”

A University of Winnipeg scientist leads an international team of researchers who may have found a loophole in the laws of physics.

"All of magnetic (knowledge) is based on 'You can't have a single pole,' " explained Wiebe, a graduate of the U of W and Transcona Collegiate. There is always a north pole and a south pole, and a single pole cannot occur naturally.

Screwworm fly detected in Texas decades after cattle threat was largely eradicated in US

John Hanna, The Associated Press 4 minute read Updated: 6:55 AM CDT

The New World screwworm fly has reached south Texas, the U.S. Department of Agriculture confirmed Wednesday, the first time in decades that the parasite with flesh-eating larvae has threatened the nation's cattle industry and only the third time it's appeared in the U.S. in that time.

Agriculture Secretary Brooke Rollins said the case was in a 3-week-old calf in LaPryor, Texas, about 50 miles (80 kilometers) from the Mexico border. Texas State Veterinarian Bud Dinges said he has established a 12-mile (20-kilometer) quarantine zone, prohibiting the movement of any warm-blooded animal — including pets — outside that zone without an inspection.

Rollins said there have been no other detections of the fly in the U.S., and officials were quick to say that while the fly’s larvae are a threat to livestock production, they don’t infest food. Properly treated, even the infested calf should recover, Rollins said.

Rollins, U.S. and Texas agriculture officials, and cattle industry leaders have been sounding public alarms about the fly’s movement across Mexico for more than a year, spurred on by memories of it causing tens of millions of dollars of losses — potentially billions in today’s dollars — before its eradication in the 1970s.

A garden may look effortlessly beautiful, but as with other facets of life, beauty is often shaped and cultivated.

No matter the size of the space you manage — whether it’s a large landscape or a postage-size patch — effort and strategy are required to achieve and protect the garden you create.

Wild swings in temperature, strong winds, heavy rainfall or long dry spells can disrupt the best laid plans. Whatever the weather, keep your garden looking beautiful by choosing reliable plants for areas that are at the mercy of the elements.

Practical methods that are employed early in the season will fortify your garden against water loss, improve drainage and help to maintain your garden’s beauty.
