What you don’t know can, in fact, hurt you

Editorial 4 minute read Friday, May. 22, 2026

‘What you don’t know can’t hurt you.”

It’s an interesting maxim, accurate in some settings.

But equally accurate might be, “What you won’t know, can hurt you.”

The last few years of politics — particularly in the United States but in other places as well — have been remarkably fractious and absolutist. You’re on one side or the other. You choose who to listen to, and what to believe in. People you don’t agree with are obviously stupid.

Turning Winnipeg into a quarantine zone in 2018 with the first EAB discovery may well have helped protect the province’s ash trees from the spread of the borer.

Adverse weather slows pace of seeding to below 5-year average

Gabrielle Piché 3 minute read Thursday, May. 21, 2026

High winds and a cool spring have caused a lag in Manitoba’s crop-planting season.

At this time last year, more than half of crops — at least 57 per cent — had been seeded, according to reports. By Tuesday, just 37 per cent of 2026 seeding was complete.

The pace falls behind the five-year average: 43 per cent of seeding is usually done by May 19.

A crop report from the Manitoba government points to “extremely high winds” and rainfall slowing progress.

As permafrost thaws, some headwaters in Canada’s North turn orange and toxic: study

Jordan Omstead, The Canadian Press 7 minute read Friday, May. 22, 2026

Ancient bedrock exposed by disappearing permafrost is releasing toxic metals into Canada's northern rivers, a new study says, with once-pristine subarctic streams now comparable in some cases to highly acidic, contaminated mining sites.

The findings out of Yukon point to an "unfolding environmental disaster," one co-author said, and adds to alarm over the rapid climate-fuelled changes in the North.

"We don't know the end point, but there's nothing about this that gives me any feeling of like, 'oh, we're going to be OK'," said co-author Sean Carey, a professor at McMaster University.

"I'm not even a gloomy person. This looks pretty gloomy."

Generic semaglutide to hit Canadian pharmacies this week at a fraction of the cost of Ozempic

Nicole Ireland, The Canadian Press 5 minute read Thursday, May. 21, 2026

TORONTO - Two generic versions of Ozempic are set to start arriving in Canadian pharmacies this week, which means patients who use the drug to treat diabetes or for weight loss may have more options for a fraction of the cost.

Health Canada approved both Dr. Reddy's and Apotex's generic semaglutide — the active ingredient in brand-name Ozempic — about three weeks ago.

Apotex is based in Canada and said it began shipping its product on Tuesday.

India-based Dr. Reddy's said in an email that its semaglutide has already arrived in "select" Canadian pharmacies and will be available more widely across the country in the coming days.

May long weekend second-coldest on record

Morgan Modjeski 3 minute read Tuesday, May. 19, 2026

The May long weekend was one of the coldest on record in Winnipeg.

The average daily high for the three days failed to reach double digits, hovering between 9.3 C to 9.6 C, said Matt Loney, a meteorologist with Environment Canada.

It’s the second-coldest on record, failing to topple the record average daily high of 6.3 C logged on May long 1882.

“It’s definitely abnormal,” said Loney of the preliminary figures. “You wouldn’t expect temperatures to be that low, but it can happen and it has happened before.”

I know things aren’t going well when cracks keep forming on my clay — but not to worry. I’d been paying attention when instructors Jillian Sheedy and Joanne Roberts told me how to deal with this problem.

So I confidently dip my brush into the water and start moistening my clay to smooth it out. Except I’ve added a bit more water than I should have, and now the clay is wet and extremely sticky.

Beside me, Roberts smiles reassuringly.

“It’s a task that requires a little bit of patience,” she says, carefully removing the brush from my hand.

A mop, a broom and a calmer mind. Why some find mental health benefits in everyday tasks

Katherine Roth, The Associated Press 4 minute read Wednesday, May. 20, 2026

NEW YORK (AP) — It's spring cleaning season, and for some people that can mean drudgery or anxiety.

But experts from Zen monks to psychologists say there are mental health benefits to be found in such manual chores as sweeping, mopping and clearing away clutter. These tasks can encourage mindfulness or permit the mind to wander, all while producing a concrete sense of achievement in accomplishing the basic tasks of daily life.

As one famous Zen saying goes:

“Before enlightenment, chop wood, carry water. After enlightenment, chop wood, carry water.”

WHO chief concerned over ‘scale and speed’ of Ebola outbreak as Congo reports 134 dead

Justin Kabumba, Monika Pronczuk And Jean-yves Kamale, The Associated Press 7 minute read Wednesday, May. 20, 2026

BUNIA, Congo (AP) — The head of the World Health Organization on Tuesday expressed concern over the “scale and speed” of an outbreak of a rare type of Ebola known as Bundibugyo in eastern Congo, where authorities reported 134 suspected deaths and more than 500 suspected cases.

The virus spread undetected for weeks after the first known death as authorities tested for a more common type of Ebola and came up negative, health experts and aid workers said. The Bundibugyo virus has no approved medicines or vaccines.

In Bunia, the site of the first known death, health workers in protective gear moved among residents wearing fabric masks. “I know the consequences of Ebola, I know what it’s like,” said a worried resident, Noëla Lumo.

Congo was expecting shipments from the United States and Britain of an experimental vaccine for different types of Ebola, developed by researchers at Oxford, said Jean-Jacques Muyembe, a virus expert at the National Institute of Biomedical Research.

A critical project in waiting

Stuart Williams 4 minute read Saturday, May. 16, 2026

Like most Manitobans I live in the city. I live in a home built about a century ago, in a well-treed neighbourhood. A 27-year-old gas furnace heats my home — one that needs replacing soon. I’d love to quit burning gas and electrify.

The options aren’t great. Electric heat costs more than double what gas does. Air source heat pumps work much of the winter, but fail during our worst cold snaps, leaving us dependent on expensive electric heat or gas backup — plus a noisy outdoor unit that ruins the patio.

If I had more land, like those with larger rural properties, I could bury horizontal coils in the ground for a fraction of the cost of drilling. But on my small city lot the only option is drilling 400- to 500-foot boreholes in the front yard. Expensive, even with Efficiency Manitoba incentives.

So: keep burning gas, or put up with a noisy compressor and still need a backup heat source. Those are my choices. But they don’t have to be.

Pair of bird books offer fascinating insight into the avian world

Reviewed by Gene Walz 5 minute read Saturday, May. 16, 2026

These two newly-released bird books couldn’t be more different. Jackie Morris and Robert Macfarlane’s The Book of Birds is artful and poetic; Louis Lefebvre’s A Bird’s IQ is analytical and academic. Each would make an attractive addition to the libraries of people interested in birds — but not without certain provisos.

The subtitle of The Book of Birds is deceptive — it’s not really a “Field Guide” in the usual sense, too substantial and beautiful to carry along on a bird outing. In hardback with a blue cloth spine and a blue-ribbon page-holder, it’s more like a church song missal than toteable identification helper. It’s best kept inside, protected from wind and weather and damp fingerprints.

The Book of Birds is a follow-up to Morris and Macfarlane’s previous collaboration The Lost Words. When the Oxford Junior Dictionary dropped a bunch of words connected to the natural world (such as acorn, otter, fern, newt and wren), the renowned artist and celebrated author created a “spell book” to conjure back 20 of those words and bring increased awareness of the things the words describe. It proved to be immensely popular.

Here they focus on 49 birds, presented alphabetically from avocet to kestrel to sparrow to yellowhammer, that are in danger of disappearing completely from the natural (European) world. Morris provides the spectacular bird illustrations, and Macfarlane waxes poetic on each of them in the hopes readers will not just identify birds, but “identify with them.”

The dangers of gambling on nuclear power

Anne Lindsey 5 minute read Friday, May. 15, 2026

Dismissing climate science, setting Canada apart from most nations and planting us firmly in the United States’ camp, the Carney government is betting the farm on a “nuclear renaissance.”

There have been numerous indications this was coming. But Energy Minister Tim Hodgson’s April 29 statement to the Canadian Nuclear Association, following immediately on the launch of the “Canada Strong Fund” left no doubt that our investment banker prime minister is determined to pursue his nuclear energy superpower dreams.

As the UN Climate Envoy, Mark Carney famously said there is “no path to net zero without nuclear.” This has been a mantra of successive Liberal governments even as Canada’s last nuclear build was in the 1980s, and nuclear’s share of global electricity production has been steadily declining. It’s also been the rallying cry of nuclear advocates spending big to persuade anxious populations experiencing floods, droughts and wildfires that nuclear power will solve our climate disaster in the making. That claim is false.

Eight years ago, the Liberals rolled out their “SMR roadmap,” predicting the first (slightly) smaller new reactors would be operational in 2026. It isn’t happening. A new report by M.V. Ramana and Susan O’Donnell — Assessing Small Modular Nuclear Reactors in Canada — details the $4.5 billion spent by Canadian governments on SMRs with zero kilowatts of electricity generated to date. Most of that money went to the potential first SMR in Canada, the BWRX 300, an American design by GE Hitachi that uses enriched uranium fuel, not available in Canada.

Astronomers believe they’ve detected an atmosphere around a tiny, icy world beyond Pluto

Marcia Dunn, The Associated Press 3 minute read Saturday, May. 16, 2026

CAPE CANAVERAL, Fla. (AP) — A new study suggests that a tiny, icy world beyond Pluto harbors a thin, delicate atmosphere that may have been created by volcanic eruptions or a comet strike.

Just 300 miles (500 kilometers) or so across, this mini Pluto is thought to be the solar system's smallest object yet with a clearly detected global atmosphere bound by gravity, said lead researcher Ko Arimatsu of the National Astronomical Observatory of Japan.

“This is an amazing development, but it sorely needs independent verification. The implications are profound if verified,” said Southwest Research Institute's Alan Stern, the lead scientist behind NASA's New Horizons mission to Pluto and beyond. He was not involved in the study.

The finding offers fresh insight into our solar system’s farthest, coldest objects in a region known as the Kuiper Belt. Researchers used three telescopes in Japan to observe the object in 2024 as it passed in front of a background star, briefly dimming the starlight.

Seeding clock ticks loudly on Prairie fields

Laura Rance-Unger 4 minute read Saturday, May. 2, 2026

If the forecast holds, Manitoba fields will be crawling with equipment this week, as the race to seed this year’s crop begins.

An early-May start to seeding is right on track by historical standards, but still feels late this year, partly because it’s been so cold. Seeding dates have been edging earlier over time, especially for crops such as wheat, as farmers discover they can get away with super-early seeding under the right circumstances.

Due to the compressed growing season characteristic to this part of the world, it’s well-documented the later the crop is seeded, the lower it yields. However, seed too early and there’s a risk that a late-spring frost will force farmers to reseed some fields.

For most, it’s a gamble worth taking.

Colin Rémillard is obsessed with the weather.

When he and his family opened Winnipeg gardener’s staple Jardins St-Léon Gardens for the 2026 season on Wednesday, it came after weeks of chilly weather. But with staff itching to go — and customers waiting — they decided to open the doors after a “mad dash” to bring in produce and tag every product in the store one day earlier.

“Everything seemed to roll fairly well. We’re in good shape. It’s going to be a colder spring, that’s just reality,” Rémillard said from the garden centre Friday.

“We’ve had really nice springs for the past one or two years. We always remember only one year in the past, so we think this is unusual, but it is pretty normal to have this amount of cold.”

Assiniboine Park Conservancy is rallying the troops to stop the invasion.

Saturday will be a bad day for European buckthorn at the park, as forestry staff are hoping 100 volunteers will show up to help clear the problematic plant.

“It’s a big issue and there’s a lot of it,” said Barret Miller, the park’s manager of education and programming.

This is the first time the conservancy is asking for help from the public to remove the invasive weed from the Winnipeg green space. The section being targeted is in the heart of the park, just south of the cricket fields.

‘Desperation’ drives women to private menopause care

Carol Sanders 5 minute read Saturday, Apr. 25, 2026

Some women are paying private clinics up to four times the amount the public health system pays doctors for menopause primary-care visits patients can get free.

One Winnipeg woman said “desperation” drove her to make an appointment with a private clinic that charges $385 for an initial assessment by a nurse practitioner.

Erika, who did not want her last name published, said for the past year she’s suffered worsening menopause-like symptoms, including night sweats, brain fog and heavy menstrual periods. The single mother who works two jobs and turns 40 this summer said her family doctor and another primary-care physician she went to both told her she’s too young for menopause.

Neither, evidently, assessed her for perimenopause, the transition leading to menopause. During that time — which can begin when a woman is in her 30s and last for several years — hormone levels fluctuate and produce, in many cases, the symptoms Erika described.

Syrup season in swing

Louise May has been tapping the trees at the St. Norbert Arts Centre for 37 years, extracting the nectar that becomes maple syrup.

May began making syrup as a way to connect with the trees and continue in the footsteps of the Trappist monks who originally planted the maple trees more than a century ago.

Recently, the endeavour has taken a more spiritual turn as May began collaborating with kookum Christine Cyr and sharing the syrup for a strawberry heart medicine used during Sundance ceremonies, which include a four-day fast.

“This is a really powerful medicine,” says Cyr. “It physically and spiritually helps people to get through” the ceremony when it is typically taken on the third day of the fast. At the beginning of the season, community members drummed, sang, and offered tobacco to each tree as May put the taps in.

Six years after a coalition of four northern Manitoba First Nations banded together to conserve the province’s last major undammed river, the Seal River watershed is “on the cusp” of permanent protection.

On Friday, the Seal River Watershed Alliance and the provincial and federal governments released a joint proposal to designate the 50,000-square-kilometre ecosystem — one of the world’s largest intact watersheds — as an Indigenous Protected and Conserved Area.

“This announcement is an absolutely historic moment in time where we have all different levels of government (and) … the nations coming together to preserve some of the most beautiful areas in the world,” Manitoba Environment Minister Mike Moyes said Friday.

“I am so proud to be part of a government that is moving forward on this historic agreement that is going to protect seven per cent of Manitoba.”
