What is the average job offering in Canada? How does it compare? What occupations pay significantly more? Do they pay that immediately after joining or the good compensation does not kick in until quite a few years has passed? How large are those professions by the headcount?

I think we can find the source of this distortion if it exists. All I can say right now is that areas where you have access to money not backed by productivity tend to trump programming or any other jobs where the employer has to make ends meet. Those areas are usually law, sometimes medicine (often not), and some public sector / government contractors.
