The issue is that there is an misunderstanding of what is happening and location.

Based on u/garlicroastedpotato first comment of this

>This isn't fracking. This is the Canadian oilsands.

He is very likely referring to the open pit mining/surface mines of the oilsands. It is pretty much what everyone refers to when they say the oil sands.

The article is talking about the oil sands formation. It is actually fairly large, it goes so far south that the oil fields in Montana and North Dakota are part of that oil sands formation. To get access to the oil in that formation, if you are not doing open pit mining you are pretty much doing drilling which is part of the process of fracking. On top of that Fracking and Steam-assisted gravity drainage is very similar in nature.

And considering u/garlicroastedpotato said it isn't fracking in his comments, he has to be referring to the open pit mining commonly referred to as the Canadian oilsands.

And if you look at the article, the earthquake is around the the Peace River oil sands deposit. Very far away from the open pit mines.

Ergo, u/garlicroastedpotato is both right and wrong. He is right in what is happening, but wrong terms and locations. And because he used the wrong terms and location, he is overall wrong.
