TO BEGIN WITH, I WILL ADDRESS THE CLAIM BELOW:

1. The standards are so high in canada to practice medicine, 2. even just to be accepted in a med school...let me doubt about your chances to do something with a such diploma.

I really don't think anyone would understand what you mean by "standards being high to practice medicine" So, I won't bother trying to understand your polemic statement like this, without wasting my time debating what you mean, here are some of the top 6 countries in the world in areas of sciences & medicine (lest we forget). Rankings for 2006:

Therefore, even just to be accepted in a med school, has nothing to do with highest standards, than a systemic propaganda that benefits from keeping intellectual competition at bay. I know many many students who were students in Canada, with GPAs ranging from 3.7 to 3.9, who never got accepted into any Canadian med-school. Yet, these students got accepted to an American Medical School. Are you suggesting that Canadian standards admit only those with a GPA of 4.0? Why then does Canada not appear on the above ranking? Even more is that, I know students who have been admitted to with far lower GPAs than those that left Canada and joined universities like Creighton in Nebraska and others.

As you have confidently pointed out: "it's more a question of how much money the government is willing to put". You are right however, if the government is not willing to put in money, the best way to keep one's salary high is by keeping everyone else out of the system and crying wolf that you are overloaded with work while you enjoy the pain (false dramatization of things), while they really don't want real change of the circumstance.

And then you continue to say:
"...let me doubt about your chances to do something with a such diploma [in Canada]. This makes me wonder why you make such a statement. This statement sounds like a pre-emptive attack to discourage anyone daring to go and train out of the country (Canada) while you said NO to them and come back to put pressure on changing things. Canada, has more that 3000 foreign trained doctors/specialists, some of whom have worked with UN(WHO) and yet working in Pizzarias, McDonalds, Tax drivers etc etc. Instead of getting concerned with those that are now training out of the country, first get concerned with those that are roughing it out within the country.

TOP-DOWN POLITICS:
It is easy for anyone to achieve economic development, but not easy to achieve political development and avoid labour abuse. It is easy to boost one's international profile with propaganda than to resolve issues at home. Hence, it is attractive to say: "The world knows; Everyone knows, People know, etc etc etc" Just to affirm the antecedent.

N.b.: The graphic image of Rankings, did not come as expected. But it still is readable. The only problem is you won't be able to read what the individual numbers represent. Nonetheless, they are in order of their importance regarding the issue in question.
