Depending on one's natural resources, in this case, oil, is not always a good thing. Putting all of your eggs in one basket, so to speak is risky. Should they all break, what do you have for an encore?
We've always been a country dependant on our natural resources -- wood, steel, oil, mining, etc., -- but truthfully, a slight change in economic diversity would do well. The environment, as an example, presents us with challenges and ideas that can transcend into reality, in the areas of ways of dealing with a new economic path.
Technology, innovation, application, flexibility, creativity, and diversity are integrated, and can be, into our economy much more than ever, if our levels of governments, industry, and other sectors can showcase more of a willingness and inclination to go that route.
I can imagine a Canada with 60 million people, living and working all over the country, yes, even in the North, with a transportation hub second to none in the world, and an economy so diversified that she would be the envy of the world. A Canada where Mother Nature is embraced, where resources are renewable, where some of the greatest achievements in transportation have been made ("from sea unto sea"), where the words 'branch plant economy' is not too prevalent, where the economy is vibrant and robust, and so much more. Ah, nice dream, eh?
