That may be true, but at a significant cost. Skilled labour contributing to GDP is rather more useful than trashing the place and making a quick dollar. Just comparing the dollars masks this.
We're still a resource extraction economy in Canada. If it's not oil & gas, it's timber, mining, water, fish, food. You look at every major export from any province in Canada and it's mostly resources. Ontario is cars, which I'm not sure is any better.
The importance of the traditional resource industries feels like an out of date meme leveraged for political reasons. It's not the future for Canada.
