Harmful algal blooms work by disrupting food webs, Dr Caron said. Creatures such as shellfish, anchovies and sardines consume the toxins before then being eaten by larger marine mammals. "They eat a meal of those highly toxic fish and then they become toxified themselves, and if they get enough of that material, it of course can kill them, which is happening now," he said.
Atlantic Canada ocean temperatures set records again in 2022
Ocean temperatures in Atlantic Canada set record highs again in 2022, according to the latest assessment released by the federal Department of Fisheries and Oceans. Results from the annual Atlantic Zone Monitoring Program show surface, intermediate and bottom temperatures were well above normal last year. "It was widespread. It was everywhere," said Peter Galbraith, a DFO research scientist in Mont-Joli, Que. "It was really, really warm across the zone."
High levels of E. coli bacteria close 2 Moncton lakes
The City of Moncton says Jones Lake and the lake at Centennial Park are closed to recreational use until further notice because of high E. coli counts.

Edmonton weather: Heavy rainfall raises water level on North Saskatchewan River
Welcome news as some areas in the province deal with flooding and high water levels. The City of Edmonton sent a public service announcement on Tuesday warning people to “exercise extreme caution around the North Saskatchewan River and its tributaries.” “Due to the continuous rain, the river, as well as shorelines and trails directly near the river, may be unsafe,” said the announcement. “Edmontonians may expect high water levels and increased current flow in the coming days. This may cause some flooding in areas running along the North Saskatchewan River and other natural waterways.”

Evacuation orders issued for two regions in Woodlands County, Alta., due to flash flooding
Flash flooding evacuation orders are in effect for two regions in Woodlands County, Alta., about 180 kilometres northwest of Edmonton, due to rising waters on the Athabasca River which is causing overland flooding. The order is in effect for residents in the Township Road 620A area along the Athabasca River, east of the hamlet of Fort Assiniboine and for the Flats Road area along the river. The orders came into effect Wednesday evening and require all residents to evacuate the area immediately. Rising waters are causing flooding and washing out roads and people have been advised to drive with caution and avoid impacted roads.
Hidden Beneath the Surface
In just seven decades, the scientists say, humans have brought about greater changes than they did in more than seven millennia. Never in Earth’s history has the world changed this much, this fast. Never has a single species had the capacity to wreak so much damage — or the chance to prevent so much harm. “It’s a line in the sand,” said Francine McCarthy, a professor of Earth sciences at Brock University in Ontario, who has led research on Crawford Lake. “The Earth itself is playing by a different rule book. And it’s because of us.”

Alberta floods: 10 years later
It’s been 10 years since the historic floods of southern Alberta that were deadly, expensive and resulted in the first ever declaration of a State of Provincial Emergency in Canadian history. Over 100,000 people were evacuated from their homes in communities throughout southern Alberta and five people lost their lives. There was more than $5 billion dollars in damages and 55,000 square kilometres of land was directly impacted by the floods; an area nearly 70 times the size of Calgary.
Government of Canada moves forward on federal pesticide commitments
Today, Health Canada, along with Environment and Climate Change Canada (ECCC), and Agriculture and Agri-Food Canada (AAFC), announced the next steps toward a sustainable approach to pesticides management in Canada. Establishing Maximum Residue Limits (MRLs) is one component of Health Canada’s rigorous pesticide risk assessment process. Health Canada scientists consider information from all available scientific studies and conduct a dietary risk assessment before they set MRLs.
It's been 10 years since the Big Flood. How the changing climate is shaping life in Calgary
In the decade since the Big Flood of 2013, Calgary has seen a number of extreme weather events and scorching, smoky summer days. Four Calgary disasters are included in the Insurance Bureau of Canada's Top 10 list of costliest years for insured losses in Canada — three since the flood, the fourth occurring the year before. The past decade has seen a surprise September snowfall in 2014, a devastating hailstorm in 2020 that resulted in $1.2 billion in damages, and a sweltering and deadly heat dome in the summer of 2021. A number of "catastrophic" weather events have been recorded in almost every year since June 2013, resulting in billions of dollars in damages.
Wildfire, rain and snow: Alberta communities grapple with flooding after storms
Flood watches remain in place for the McLeod River and Athabasca River at Whitecourt. Water levels on the two rivers are expected to peak Tuesday evening, putting low-lying areas of Whitecourt at risk. Jasper National Park has also been hit hard by recent rain and snow, resulting in road and trail closures and treacherous conditions. In a statement Monday officials said 100 mm of rain and 55 centimetres of snow had fallen in some locations and Maligne and Miette roads have been closed.
How Canadian wildfire smoke could impact the Lehigh Valley’s water, crops long term
Weeks after the Lehigh Valley turned sepia toned from Canadian wildfire smoke, the skies have cleared and there’s even been some rain, even though it hasn’t been enough to push much of the state out of moderate drought status. While environmentalists and researchers said impacts on the region’s crops and water may be few due to the short duration of smoky days, it’s a largely understudied topic. However, as climate change worsens and the chance for more wildfires increases, experts said the impacts could similarly escalate.
An Indigenous approach to understanding water
“siwɬkʷ (WATER) IS SACRED AND IS LIFE FOR ALL PEOPLE. We know from our histories and our knowledge that water is one of the most important resources available to humans and animals.” But for Dawn Machin and Sarah Alexis, both from snƛ̓x̌ʷx̌ʷtan (Six-Mile Creek area in the North Arm of Okanagan Lake), there’s a disconnect between what water represents to humanity and how it’s perceived.
Enbridge to pay Bad River band $5.1M in Line 5 profits, move pipeline by 2026: judge
Calgary-based Enbridge Inc. must pay an Indigenous band in Wisconsin more than US$5 million in Line 5 profits and relocate the controversial cross-border pipeline within the next three years, a U.S. judge says. A rupture on territory that belongs to the Bad River Band of the Lake Superior Chippewa would constitute a clear public nuisance under federal law, district court Judge William Conley said in a decision late Friday.
Residents concerned about high water-sewer charges; want bills separated
Two North Battleford residents hope to see some clarity in their water-sewer bills from the City. Jane Nielsen and Darryl Williams spoke at this week’s council meeting about their concerns with high rates, and questioned why the bills aren’t broken down for water and sewer separately. “It is my opinion, that they should be treated as separate entities, since water consumption and use of the sewer are two distinctly different services,” Nielsen said.
Hot and dry summer could affect Calgary's water levels
The beginning of June in Calgary has been hot and dry, and that could have an affect on the city’s water supply through summer. Environment Canada and Climate Change Canada (ECCC) says Calgary has come into the summer season with dryer than normal conditions — spring 2023 ended as the fifth driest spring on record.
UK Hosepipe Ban Planned for Southeast Due to Record Water Demand
Southeast England faces a hosepipe ban later this month, after dry weather and record demand strained a utility’s capacity to provide enough drinking water. The ban from June 26 will impact households in Kent and Sussex, South East Water Ltd. said in a statement on Friday. People using hosepipes after that date to water gardens, wash cars and fill swimming pools will risk fines of as much as £1,000 ($1,280).
