The Alberta Energy Regulator has warned Imperial Oil about more wastewater problems at its Kearl oilsands mine in northern Alberta.

Alberta's 2019 decision to cancel funding for an elite wildfire-fighting crew in 2019 came despite pleas to keep the Rapattack program from at least three municipalities, including one that has since been evacuated during this spring's blazes.

As Albertans begin what could be a bitter and divisive provincial election campaign, one of the province's most popular musicians wants to remind them of an issue that brought everyone together a couple years ago.

New federal research suggests greenhouse gas emissions from the Alberta oilsands may be significantly underestimated, adding to a growing pile of studies that say our understanding of what is going into the atmosphere is incomplete.

Alberta's United Conservative Party government released a climate plan Wednesday that it hopes will take the province to net-zero carbon emissions by 2050 without offering many details, targets or new measures to get it there. 

In a note to area First Nations, the Alberta Energy Regulator says the water is from a pond used to settle suspended solids in surface water collected from parts of the site that haven't been mined. Once the sediments settle, the water is emptied into a creek that drains into the Athabasca River. 

Alberta's energy regulator is reconsidering a project it approved months ago after receiving a critical report on Fort Hills Energy's plan to mine oilsands from a unique carbon-storing wetland.

Alberta's energy regulator has confirmed hazardous chemicals are present in a small waterbody after two releases of tailings-contaminated wastewater from Imperial Oil's Kearl oilsands mine.

The Alberta government waited a month before calling an emergency response to one of the biggest releases of oilsands tailings in the province's history, a leaked document shows.

Alberta's energy regulator has defended its finding that the province's largest recorded earthquake was caused by oilpatch activity, saying the pattern of temblors since last fall clearly points to a water disposal well even though there's no suggestion rules were flouted.
