You are missing the market here. If you pay Canadians high wages and you set high prices for fruits you cannot sell them in poor countries. And this means that the profits for that Canadian corporation will be cut in half. And the rich people at the top will suffer.
In the mean time poor countries will start planting their own trees with their own people and appropriate prices for their country. And Mexico will have their own corporation making money.
