That's not true, either.  It's much more complicated.  Here's a totally Alberta friendly source which still dispels these ancient myths.

"The federal government adopted a wide set of measures to reach these goals. It issued grants to encourage oil drilling in remote areas, especially the North, where Ottawa, not the provincial governments, had jurisdiction over natural resources and the right to earn revenue from them. It gave grants to consumers to convert away from oil to gas or electric heating. And it imposed a 25 per cent federal ownership share on all oil and gas discoveries made by private companies in the North, and offshore."
