Obviously federal regulations and taxes under the Liberals aren't the problem since Newfoundland's offshore has seen commitment of $ billions  in new investment in oil production this year.  

Maybe you need to ask Husky and Suncor why they're increasing their investment in Newfoundland's offshore instead of using that capital in the oil sands.  Especially since Newfoundland's taxes are very much higher than Alberta, it's clear that tax rates aren't their main consideration.
