oilsands tailings

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

The Alberta Energy Regulator’s president and CEO was in the hot seat Monday at a parliamentary committee meeting where MPs quizzed him on the regulator’s role in failing to quickly communicate information about multiple tailings leaks in northern Alberta to downstream communities and various levels of government.

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.

The recent revelation of a massive leak from Imperial Oil’s tailings ponds highlights the question of what to do with the rest of the oilsands waste accumulating along the Athabasca River.

Pollution from oilsands tailings dominated the agenda at the Dene Nation Water Summit this week as northern Indigenous leaders and community members discussed how to respond to recent news of multiple leaks hidden for months from neighbouring Indigenous communities.

Recent leaks of toxic tailings from northern Alberta oilsands mines have revealed serious flaws in how Canada and Alberta look after the environment, observers say.

The coverup of Imperial Oil’s latest spill of toxic tailings water at the Kearl mine north of Fort McMurray is an outrageous breach of trust.

Alberta's nine-month silence over two releases of toxic oilsands tailings water is "worrisome," says federal Environment Minister Steven Guilbeault.

Federal politicians have joined the chorus of anger over Imperial Oil’s failure to alert a downriver First Nations community of a massive release of oilsands tailings first reported last May.

Releasing treated oilsands tailings into the environment isn't the only solution being considered to clean up the massive toxic ponds in northern Alberta, federal Environment Minister Steven Guilbeault says.

A United Nations body that monitors some of the world's greatest natural glories is in Canada again to assess government responses to ongoing threats to the country's largest national park, including plans to release treated oilsands tailings into its watershed.

According to a recent report, the federal government is in the process of developing regulations to allow oil producers to treat and release the water in those ponds, which contain toxic chemicals like mercury, ammonia and naphthenic acids.

Environmental groups are calling on the federal government to step in after oilsands tailing ponds grew by 90 million cubic metres in 2020 despite a drop in oil production, according to a report released last week by the Alberta Energy Regulator (AER).
