Carney delays electric vehicle sales mandate by one year, launches review

Nick Murray, The Canadian Press 7 minute read Monday, Sep. 22, 2025

OTTAWA - The federal electric vehicle sales mandate will not be implemented in 2026 as planned, Prime Minister Mark Carney said Friday, pushing back by at least a year a policy that would have set minimum sales targets for electric and plug-in hybrid vehicles.

Introduced by the Liberals under former prime minister Justin Trudeau, the mandate would have required 20 per cent of all new vehicles sold in Canada next year to be electric.

The standard as written is to rise steadily each year until 2035, by which point all new light-duty vehicles sold in Canada were to be fully electric or plug-in hybrids.

But at a press conference in Mississauga, Ont., Carney said he is suspending the mandate for 2026 and launching a 60-day review of the program to help find "future flexibilities and ways to reduce costs."

BEIJING (AP) — While China's men's soccer team hasn't generated much excitement in recent years, humanoid robot teams have won over fans in Beijing based more on the AI technology involved than any athletic prowess shown.

Four teams of humanoid robots faced off in fully autonomous 3-on-3 soccer matches powered entirely by artificial intelligence on Saturday night in China's capital in what was touted as a first in China and a preview for the upcoming World Humanoid Robot Games, set to take place in Beijing.

According to the organizers, a key aspect of the match was that all the participating robots operated fully autonomously using AI-driven strategies without any human intervention or supervision.

Equipped with advanced visual sensors, the robots were able to identify the ball and navigate the field with agility

PORT STEPHENS, Australia (AP) — The ferry was late, but not because of the usual traffic. Sydney commuters watched from an idling boat this month as humpback whales the size of buses surfaced nearby, halting the vessel’s passage across the harbor. The curious mammals seemed to be watching them back.

In June and July, it’s not uncommon for whales to stop water traffic in Sydney. Winter heralds the opening of the so-called humpback highway, a migratory corridor along Australia's east coast used by about 40,000 of the massive creatures as they travel from feeding grounds in freezing Antarctica to tropical breeding areas off Queensland state.

“It’s blubber to blubber,” said Dr. Vanessa Pirotta, a wildlife scientist at Macquarie University in Sydney and author of the book “Humpback Highway.” During peak traffic periods the bustling coastal city of 5.5 million people becomes one of the world’s few urban centers where you might see a breaching whale on your morning walk, while buying a coffee, or waiting at a bus stop – anyplace you can see the ocean.

French Open tennis players say nasal strips aren’t just for snoring

Tom Nouvian, The Associated Press 4 minute read Sunday, Sep. 21, 2025

PARIS (AP) — If more tennis players find themselves breathing easier, it might just be thanks to Carlos Alcaraz.

The four-time Grand Slam champion, whose bid for a second consecutive French Open title was scheduled to continue with a third-round match Friday night, has often worn a nasal strip in matches since last season — although not during his first two contests at Roland-Garros this week — and the sport's other athletes took note.

After all, if Alcaraz finds something useful on the court, their thinking goes, maybe it makes sense to give the adhesive bands a shot.

“I saw Carlos playing in it,” said 18-year-old Mirra Andreeva, a semifinalist in Paris last year and the No. 6 women's seed this time. “I’d be pretty interested to try and see if there is really a difference. If he plays matches in it, then probably there is.”

Guardians’ right-hander Ben Lively will have Tommy John surgery and miss rest of the season

The Associated Press 2 minute read Friday, Oct. 3, 2025

DETROIT (AP) — Guardians pitcher Ben Lively will undergo Tommy John reconstruction surgery on his right elbow and will be sidelined for the rest of the season.

The Guardians said before Friday night's game at Detroit that Lively's surgical date has not been set, but it will be performed by Dr. Keith Meister in Arlington, Texas. The right-hander is expected to miss 12-16 months.

Lively — on the injured list since May 13 due to a strained right flexor tendon — sought a second opinion on his right elbow with Meister earlier this week. Meister confirmed the presence of a flexor tendon injury while also noting medial elbow joint laxity due to an insufficient ulnar collateral ligament.

The Guardians physicians and Meister recommended UCL reconstruction along with flexor tendon repair.

Inquiry must be called to get answers on sand mine scandal

Tom Brodbeck 5 minute read Friday, May. 23, 2025

It’s pretty clear by now that an inquiry should be called into the Sio Silica scandal.

Ethics Commissioner Jeffrey Schnoor released his long-awaited report into the matter this week. He found that former premier Heather Stefanson, then deputy premier Cliff Cullen and then economic development minister Jeff Wharton, violated the province’s Conflict of Interest Act by attempting to approve a licence for a controversial silica sand mining project after their government was defeated in the Oct. 3, 2023 provincial election.

All three ministers pushed to have a Class 2 licence under the Environment Act approved for Sio Silica, days before the new NDP government was sworn into office.

They did so even though they knew, or ought to have known, that it violated the “caretaker convention,” a longstanding constitutional principle in Canada that prohibits governments from making major policy decisions once a general election is called (unless it’s related to an urgent matter of public importance).

NEW YORK (AP) — Billy Joel has canceled all his upcoming concerts across North America and England after being diagnosed with fluid buildup in his brain that has affected his “hearing, vision and balance.”

Joel revealed on Instagram that he has Normal Pressure Hydrocephalus, “a brain disorder that can affect brain-related abilities, including thinking and concentrating, memory, movement and more,” the Cleveland Clinic says.

“This condition has been exacerbated by recent concert performances, leading to problems with hearing, vision and balance,” according to a statement from Joel’s team. “Under his doctor’s instructions, Billy is undergoing specific physical therapy and has been advised to refrain from performing during this recovery period.”

In an accompanying statement, Joel said, “I’m sincerely sorry to disappoint our audience, and thank you for understanding.”

‘Special to the world’: Supporters hope to save beloved Drumheller dinosaur

DRUMHELLER - A plan to send Tyra the tyrannosaurus, the popular tourist attraction that towers over the skyline in Drumheller, Alta., into proverbial extinction has sparked demands that she be spared.

The town of 8,400 northeast of Calgary bills itself as the Dinosaur Capital of the World. Home to the famed Royal Tyrrell Museum, the community also has statues of dinosaurs that look like they've crawled out of "The Flintstones" cartoon greeting people on the streets.

There's an extinct reptile riding a motorcycle. A triceratops in a frilly dress sits on a bus bench. Another dinosaur wearing a fireman's hat and holding a hose is poised outside a fire station.

The biggest is Tyra, standing across from the intersection of Gorgosaurus Street and Tyrannosaurus Drive near a visitor information centre. A nearby ice cream stand offers fossils, T-shirts and dino toys.

Maximilian Scott is a vertebrate paleontologist who focuses on extinct animal behaviour and behavioural evolution. Scott, 27, from Ovid, Mich., is in the last year of his master’s degree at the University of Manitoba studying mosasaurs, an ancient marine lizard that lived in Manitoba during the late-Cretaceous period.

He also offers tutoring in geology, biology, animal behaviour and conservation to people of all ages. You can find him on Instagram.

Manitoba-born scientist Peebles wins Nobel Prize in physics

Maggie Macintosh 5 minute read Tuesday, Oct. 8, 2019

The most recent Canadian recipient of the Nobel Prize in physics, cosmologist James Peebles, will be honoured with about $600,000 in prize money — and his picture will hang in at least one Winnipeg dorm room.

"He has become an icon of mine since today, this morning," said Harshan Singh, an aspiring physicist enrolled in his first-year at the University of Manitoba. "I will probably put his picture on my wall and then look at him every morning."

The Winnipeg-born, U of M educated Peebles' theories predicted the existence of dark matter and dark energy, as well as a distant radio signal created after the Big Bang.

There was a "muted murmur" among the world's scientists that he should have won the Nobel Prize 41 years ago, when two other scientists were awarded it for stumbling on the faint signals from space Peebles had first theorized with a colleague, according to the U of M newspaper archives.
