This is such a loaded question. One man's "benefits of globalization" are another's devastation and ruin.
The priority for free trade should be "fair" trade at fair prices. The pre-eminent laws and rules governing international institutions regulating international trade and finance should be those adopted under the UN Charter. The International Declaration of Human Rights and the Convention on the Rights of the Child, should, for example, be used to screen any regulations passed by the WTO or the IMF or the World Bank. The Government of Canada could help immensely by simply reminding these institutions in their negotiations that there are higher laws to which the world community has already given assent and what they're doing has to recognize this - Canada will not give assent to anything less.
