AER Continues Support for free Access CSA Standards

The Alberta Energy Regulator (AER) is continuing to support a regulator-led initiative to provide Albertans and regulated industries with free access to CSA technical standards (opens in new window) related to the energy and minerals sectors. These standards are referenced in many AER directives and are used for the safe regulation of oil, gas, mining, and pipeline operations throughout Canada.

You can download the standards for free from the CSA Group website (opens in new window). Follow these instructions (opens in new window) to get access to the standards.

The AER is a member of the Western Regulators Forum, which includes the Canada Energy Regulator (CER), BC Energy Regulator (BCER), the Saskatchewan Ministry of Energy and Resources (MER Saskatchewan), and the Office of the Regulator of Oil and Gas Operations (OROGO) in the Northwest Territories.

The AER, BCER, CER, and MER Saskatchewan are making a financial investment to provide Canadians with free online access to CSA standards for five years. The AER’s financial contribution comes from the existing industry levy. There is no increase to the levy as a result.
CSA Group is a leader in North American standards development, product testing, inspection, and global certification. CSA standards are updated regularly by technical committees established with balanced representation of volunteer members, including industry, regulators, and the public. AER technical staff participate in the development, review, and update of many CSA standards.

Major Oil Pipeline Spill in Northern Alberta

On April 9, 2026, a accident occurred at an Imperial Oil pipeline site approximately 32 kilometres northwest of Cold Lake, Alberta. This incident resulted in the release of approximately 843,000 litres of crude bitumen and salt water into the surrounding environment. The spill has drawn renewed attention to the environmental risks associated with the high-pressure extraction technologies used in the region’s oil sands.

Causes of the Incident

The spill occurred at an Imperial Oil wellsite and involved a mixture of 172,000 litres of crude bitumen and 671,000 litres of salt water. Preliminary reports indicate that the release originated from a pipeline failure. While investigations by the Alberta Energy Regulator (AER) are ongoing, previous incidents in the Cold Lake area—such as those at the nearby Primrose site—have often been linked to technical failures in Cyclic Steam Stimulation (CSS) infrastructure. In such cases, mechanical stresses or casing failures can allow high-pressure fluids to bypass geological barriers, though the specific mechanical cause of this April 2026 leak is still being finalized by technical teams.

Environmental Impact

The primary environmental concern stems from the volume of the release and the toxic nature of the bitumen emulsion. Bitumen contains heavy metals and hydrocarbons that can persist in the ecosystem.

• Soil and Vegetation: The mixture of hot bitumen and salt water can cause immediate “scorching” of local flora and long-term soil contamination.
• Wildlife: Although early reports from April 2026 suggested no immediate impacts to wildlife, historical spills in the area have proven deadly to amphibians, birds, and small mammals that become trapped in the viscous oil.
• Water Protection: The proximity to the Bonnyville Aquifer and local tributaries remains a critical concern, as salt water (produced water) can increase salinity in freshwater zones, making them uninhabitable for certain aquatic species.

Cleanup and Remediation Efforts

Imperial Oil activated its emergency response protocols immediately upon discovery of the leak. The cleanup process involves several phases:

• Containment: Crews utilized booms and barriers to prevent the fluids from migrating toward nearby water bodies.
• Recovery: Vacuum trucks and specialized skimming equipment were deployed to remove the pooled bitumen and contaminated water from the surface.
• Soil Remediation: Impacted soil and vegetation are being excavated and transported to approved waste facilities for treatment.
• Monitoring: A network of monitoring wells is typically established to ensure that no contaminants have migrated into the deeper groundwater or nearby rivers, such as the Firebag River system.

The Alberta Energy Regulator continues to oversee the site to ensure that Imperial Oil meets all provincial environmental protection standards before the cleanup is certified as complete.

Canada launches $100M coalition to accelerate carbon removal market

Canada’s carbon removal sector has received a coordinated boost with the launch of the Advance Carbon Removal Coalition (ACR), a national initiative aimed at scaling investment and demand for carbon dioxide removal (CDR) solutions.

Led by Carbon Removal Canada, the coalition is targeting $100 million in new support by 2030 through a mix of credit purchases, direct investment, and project finance.

Founding members include the Government of Canada, Bank of Montreal (BMO), ClimeFi, NorthX, Royal Bank of Canada (RBC), Shopify, and Vancity. Collectively, these organizations have already contributed more than $75 million to Canada’s growing CDR ecosystem.

“Canada has the talent, geology and clean power to lead in carbon removal,” announced Ed Whittingham, founding director of the Advance Carbon Removal Coalition. “By aligning serious buyers and investors, we’re helping advance Canada’s carbon removal sector from fragmented to financeable. That’s how you go from ambition to projects on the ground.”

The ACR is structured as a demand-side coalition designed to strengthen confidence in Canada’s carbon removal market. By creating a shared platform for participation, transparency, and engagement, the initiative aims to stimulate demand for high-integrity carbon removal credits while providing clearer market signals for developers and investors.

By aligning public and private sector participants around common objectives, the coalition seeks to reduce fragmentation that has historically slowed market development. ACR will also publicly recognize member participation and track aggregate progress toward its 2030 funding goal.

Carbon removal is widely expected to become a trillion-dollar global market in the coming decades, as governments and industries work to address emissions from hard-to-abate sectors such as cement, aviation, and heavy industry. Canada is seen as well-positioned to compete globally, with advantages in geology, engineering expertise, biomass availability, and access to clean electricity.

Despite growing momentum, Canada’s CDR sector continues to face challenges in scaling projects beyond early-stage development. Industry observers note that consistent demand signals — rather than one-off transactions — are essential to unlocking larger-scale deployment.

The coalition aims to address this gap by improving market visibility and coordination. By clarifying who is actively purchasing and investing in carbon removal, ACR intends to make it easier for project developers and decision-makers to identify credible demand and secure financing.

On March 12, the Government of Canada launched a Request for Standing Offer to purchase carbon removal credits. The offer seeks to acquire and retire permanent carbon removal credits to offset residual GHG emissions from the government’s National Safety and Security Fleet. The procurement will award up to five standing offers across five technology streams, valid until March 31, 2029.

“Canada is committed to achieving a net zero economy, and carbon dioxide removal will be essential to reaching that goal,” announced Julie Dabrusin, federal Minister of the Environment, Climate Change and Nature. “With strong policies and innovative technologies, Canada is uniquely positioned to build a globally competitive carbon removal industry. The Advance Carbon Removal Coalition will help us get there by mobilizing investment and supporting innovative Canadian projects that drive climate progress, strengthen our economy, and create demand for high integrity carbon credits.”

Toxic emissions from burning homes add new complexity to air quality risks, study finds

As wildfires increasingly encroach on communities at the wildland-urban interface (WUI), new research suggests that burning homes may introduce additional air quality hazards beyond those of traditional forest fires.

A study led by scientists at the Cooperative Institute for Research in Environmental Sciences (CIRES) found that synthetic materials commonly used in residential construction— such as plastics and insulation — can release elevated levels of harmful compounds when burned. The findings were published in the journal ACS Environmental Science & Technology.

“Urban fires are becoming more prevalent,” said William Dresser, a CIRES research scientist and lead author of the study, pointing to recent disasters such as the Marshall Fire in Colorado and the Lahaina fires in Hawaii. “There are emerging questions from an air quality standpoint of how these types of fires change exposures.”

To better understand these risks, Dresser collaborated with CIRES Fellow Joost de Gouw and researchers from Colorado State University. The team conducted controlled laboratory burns of 18 common building materials, capturing and analyzing emissions in real time.

Their analysis focused on volatile organic compounds (VOCs), a group of carbon-based chemicals known to impact both air quality and human health. The researchers observed heightened levels of hazardous VOCs, including benzene and styrene, when synthetic materials were burned. Both compounds are associated with an increased cancer risk.

The study also identified less-understood emissions, such as molecular fragments derived from nylon polymers, highlighting gaps in current knowledge about the full range of pollutants released during structure fires.

However, the researchers emphasize that synthetic materials represent only a small portion of a home’s overall mass. Wood and timber products remain the dominant building materials, and their emissions more closely resemble those from natural vegetation fires.

To assess real-world impacts, the team modelled emissions from a full house fire using typical building material compositions. These results were then compared to emissions from structural wood fires and a natural Douglas fir forest fire.

While whole-house fires did show elevated levels of certain toxic VOCs — particularly benzene and styrene — many other emissions were comparable to those produced by wood and forest fires.

“Since synthetic materials are a pretty small part of a home, we found their impact can be muted,” Dresser said. “But it was in part surprising to see the nuanced picture.”

The findings show the growing complexity of wildfire-related air pollution, especially as fires increasingly affect developed areas. According to de Gouw, the research marks an important step toward understanding how structure fires may alter environmental and public health risks.

“Our research shows clearly that some toxic compounds are higher when a home burns, relative to a wildfire,” he said. “Future work is focused on the compounds that end up in ash or can be leached from ash into waterways.”

The authors note that further research is needed to fully assess long-term environmental impacts, particularly as wildfire activity continues to intensify in populated regions.

Market Watch: Nationwide report reveals key players in biggest cleanup projects

The Bank of Canada is holding its policy rate at 2.25% — as it prioritizes stability amidst economic uncertainty and potential energy price shocks from geopolitical conflicts. The bank focuses on returning inflation to the 2% target, with officials monitoring risks while preparing for a potential slowdown in economic growth.

In its most recent meeting, Governing Council drew on analytical work undertaken at the Bank on conducting monetary policy when faced with supply shocks, summarized in Deputy Governor Sharon Kozicki’s recent speech. They agreed to keep options open while closely monitoring the unfolding conflict in the Middle East, U.S. trade policy and incoming data.

Despite the turmoil from the markets, the cleantech and remediation business continues to stay strong, and the forecast is looking solid. The global environmental remediation market is projected to grow from USD $141.87 billion in 2025 to USD $210.56 billion by 2030, at a compound annual growth rate (CAGR) of 8.2 per cent according to a report by MarketsandMarkets. The environmental remediation market is expanding as advanced clean technologies employed in bioremediation, nanoremediation, and chemical treatments enable more effective and sustainable cleanup of contaminated sites.

There is an increasing focus on developing environmentally friendly industries that prioritize pollution control and ecological balance. This shift toward sustainable industrial practices is driving strong demand for innovative remediation solutions worldwide.

Key players such as U.S.-based firms Clean Harbor Inc., Jacob Solutions Inc., Tetra Tech, Inc., and Canada-based WSP continue to innovate, positioning the market for substantial growth in the coming years.

Remediation projects in Canada are supported by the ongoing multi-billion-dollar Federal Contaminated Sites Action Plan with a recent boost from environmental policy and commitments such as the 2030 Nature Strategy, a recently announced $3.8 billion investment to protect and restore critical habitats and natural resources, and the launch of the Build Communities Strong Fund, a $51 billion 10-year infrastructure program, with water and wastewater projects dominating its first round of funded work.

Cleanup trends in 2026 indicate the integration of digital technologies into environmental workflows, an increasing tendency toward in-situ treatment methods over trucking contaminated waste long distances to landfills, and emerging prominence of Indigenous-led remediation and conservation.

This inaugural report, which reveals the massive investments and the large number of projects utilizing in-situ approaches and resource recovery, indicates a positive development in the industry and sets the stage for new and inclusive nation-building projects.

Canadian astronaut Jeremy Hansen reflects on his mission — its challenges and its joy

Jeremy Hansen waited 16 years to get his shot at going to space.  It was worth the wait. Hansen sat down with CBC News at the Johnson Space Center in Houston, Texas, on Thursday to discuss his mission.

First recruited in 2009 with David Saint-Jacques — who was the last Canadian to go to space in 2018-2019 — Hansen spent years living in Houston, training and preparing for his eventual space mission. But he never thought it would be a flight around the moon.

“You know, I would have loved to have gotten to space earlier, obviously,” he said. But NASA’s space program changed. “The shuttle ended and the moon program at that time … got significantly delayed and then it morphed. And so that’s just not how it turned out,” Hansen said. “Some of that was challenging, but also, you have to just make the best of it. And I really enjoyed the journey along the way. I’ve had some extraordinary experiences.”

But then, on April 1, there he was, sitting on top of NASA’s Space Launch System (SLS) rocket together with his three NASA crewmates, Reid Wiseman, Victor Glover and Christina Koch. Destination: the moon. That rocket was far more powerful than the space transportation system that NASA used in the shuttle days. It was more akin to the Saturn V rocket that launched the Apollo astronauts to the moon. So, how was the ride? “Launching and the ride uphill was just so fun. I mean, I just really enjoyed it. I just found myself loving it,” he said.  He wasn’t thinking about how long he had to wait to get there. “I was just thinking about that moment. And I was having a lot of fun.”

Was he sick?

But what about once he got there? Roughly 60 to 80 per cent of astronauts experience space sickness. So, did he throw up? Was he sick? “No, I wasn’t. I got so lucky,” he said. “Maybe being in a small spacecraft made that easier. It probably did. But I just felt great the whole time.”

If you’ve ever seen an astronaut before they launch into space and then when they’re in space, you might notice that their faces look puffy. That’s because there’s no gravity in space to keep bodily fluids in place and they shift upwards. Hansen said he did experience some discomfort due to this. “It just makes it a little harder to concentrate on things,” he said. “I would say like everything [was] just a little bit harder.” So Hansen wore a thigh cuff, a device that restricts blood flow in astronauts’ legs. 

“I found those to be really helpful and that would change that feeling of fullness in my head and within like an hour or two of putting it on, I would sort of feel that diminish,” he said. “That was really neat to me. … They’ve got some good tricks, and there are options for you to use.”

A water bubble problem

The Artemis II was a test mission: the astronauts were to put the spacecraft through its paces, document challenges and their overall experience. 

During the mission, there were small things that challenged them. For example, when they were taking photographs of the moon, they had to turn the lights off in the capsule to ensure there was no glare on the windows. Except, there was one problem: Earth. Earth was shining brightly in a window and lighting up the capsule. So, what did they do? They hung a t-shirt to cover it up. Then, there were the windows. The windows were numbered so that the astronauts could relay to mission control in Houston what they were seeing out of which window. Except, time and time again, they would mix them up. Hansen told CBC News that there was also a lesson to be learned from their water system. 

“We had to get used to our water system, because you would open up the valve to fill a water bag or hydrate your food and then, if you closed the valve and took it off right away, it would just keep running,” he said.

Instead, he explained,  you need to wait about 30 seconds after to take it off. They got in the habit of opening the valve and doing something and then going back and closing the valve and doing something else. 

“I did it more than once where I opened the valve, and I went to do something else and then somebody asked me for something and then I looked back and the water bag had exploded,” he said.

So, when there’s a huge bubble of water floating in a capsule filled with electronics that don’t react well to water, what do you do? “I drank it,” Hansen said, laughing. Hansen said that getting reacclimatized to Earth’s gravity hasn’t been that difficult. He puts it down to it having been a short trip — just over nine days — compared to six-month stints on the International Space Station. As for his favourite moments, he says there were many. “There’s a list of visuals [and] the physical experiences, riding the rocket uphill and coming down in the capsule, they’re all so cool,” he said. Still, Hansen said, it was more about the humanity of it all. “The human experience is what tops it, though,” he said. “We really had a good time doing this. It was really neat to hear while we were in space that people were connecting, and we didn’t know the extent until we got back. But that’s pretty awesome.”
