Curatolo cartoon. Being a new resident here I don't know all the ins and outs of provincial rivalry. I've heard that Albertans believe other Canadian provinces are slightly miffed because Alberta has lots of jobs and is making money. Alberta makes its money from oil.
I guess the reader is supposed to take the guy talking as an Albertan working on the oilsands. The punchline being that he cares about "green" because money is green. And then the big switcharoo is that he's in the provence of Ontario, not Alberta.
I don't really get the switches. Alberta digs up the stuff and Ontario refines it? Everyone should be happy and shut up because there are jobs at stake? Albertans aren't hypocrites like people in Ontario?
Whatever the deeper meaning of this cartoon, I do enjoy the Jack Davis-esque drawing style.
