Stop expanding oilsand tailings ponds, urge environmental groups


The extraction of oil from sand in western Canada has left over a trillion litres of waste stored in tailings ponds and they are getting bigger. Two environmental groups issued a report showing the cost of cleaning them up would exceed $45 billion (the amount collected in royalties) and as companies close or go bankrupt, the Canadian taxpayer could end up having to pay the bill.

‘Acutely toxic’ ponds kill wildlife

“The tailing ponds themselves, because a lot of it is water, are leaking into the Athabasca River and that carries the toxic chemicals…into the river,” says Tim Gray, executive director of Environmental Defence. “Millions of litres a day are seeping into the Athabasca River.

“They also pose a direct threat to wildlife. There’s been several events where flocks of wild fowl—geese and ducks—have landed on the tar sands tailings ponds and immediately died because they’re so acutely toxic.”


Groups demand oil companies set aside cleanup funds

Gray says this is a clear violation of the federal Fisheries Act. Dale Marshall of Environment Defence agrees and is calling on the government to force the oil industry “to clean up its act and change the way it deals with toxic waste.”

The two groups want a halt to all expansion of tailings ponds until oil companies address the problem of the existing ones. They want oil companies to be obliged to set aside the money to clean up tailing ponds and they want bankruptcy laws changed so that when an oil company goes into receivership the cost of cleaning up the ponds takes priority over other creditors.

Ponds cover an area the size of Toronto and Vancouver, says groups

“The tailings ponds have been growing for 50 years and now they cover an area that is about the same size as the city of Toronto and Vancouver together,” says Gray. “They haven’t been successfully cleaned up and so we have a mounting liability for the Alberta citizens and Canadians more broadly.”

Netiquette »

When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.

  1. RCInet.ca’s online forums are not anonymous. Users must register, and give their full name and place of residence, which are displayed alongside each of their comments. RCInet.ca reserves the right not to publish comments if there is any doubt as to the identity of their author.

Any message containing one or more words in all caps (except for initialisms and acronyms) will be rejected, as will any message containing one or more words in bold, italic or underlined characters.
  6. Use of vulgar, obscene or objectionable language is prohibited. Forums are public places and your comments could offend some users. People who use inappropriate language will be banned.
  7. Mutual respect is essential among users. Insulting, threatening or harassing another user is prohibited. You can express your disagreement with an idea without attacking anyone.

    Has Justin Trudeau ever considered these unsightly, unhealthy tail ponds before he gave the green light to the Trans Mountain Pipeline expansion?
    No doubt there will be another nasty ‘gift’ to B.C. from Alberta

  2. Peter Ashcroft says:

    We are now becoming aware of the dangers of toxic waste, and the failing to process it into an environmentally acceptable mode at the time of origination by the industrial ‘perpetrators’ ‘Waste begets more waste’

  3. Rene Albert says:

    I fully agree with taking all the necessary precautions with the oil sand companies, because with the current and future shifts from oil to renewable energy (vehicles, homes, industries, etc,) the higher cost producers (like in the oil sands) will be the first to fold up.

    And it may be sooner than we think…
