“Odd headline”
Maybe referring to the fact that it is a lot more expensive to remove and process this oil than, say from a hole in the ground in Saudi. So it’s only a viable supply as long as the world oil price stays very high. They’ll have to control supply to make sure it stays that high.
Alberta oil sands have been in continuous commercial production for over 4 decades. It has already survived multiple price swings including the very cheap oil of the late 1990's (oil reached below $10 a barrel).

The produced their billionth barrel back in 1998.
Frankly its a win win for Canada and the US. The more North American oil production the US can rely on the better - to finally be free of Islamic oil.
