Yes but..
The above figures can't be denied and paint a good likeliness of reality.
I live in Australia (but I'm a G.O.) and I make a good chunk less than my CHC Oz mates. Plus the buggars get a full month vacation/year.
However I would argue that the comparison based on living and buying houses in Canada is flawed. Many, if not half, of the G.O. pilots do not live in Canada. Many actually live in Europe. I have colleagues who are resident of Holland, U.K and France and all are G.O. pilots. Those guys would be short changed if the Canadian table of comparison is used.
I know I'm dreaming but why can't it just be "same work = same pay".
