Our economy is just as diversified as others its just that O & G is the largest component. And Ontario should be so smug. This goes back to the National Policy of Sir John A. to provide tariff barriers to protect southern Ontario industry which in turn promoted population growth. Then you had the Crow Rate which basically protected manufacturers in Ontario and Quebec and added costs for anything sent west. Oh and the Auto-Pact was a doozy too. All of this allowed for a petro-chemical industry to develop in Sarnia. Pretty hard to diversify when history has greased the success of Ontario and Quebec. So take your smugness and shove it.
