I understand that there is a tax treaty between Canada and Colombia, but I'm unclear how it all works.
I believe that the Canadian gov't will withhold 25% of my gross pay and then, at the end of the tax year, I need to file and they will correct things. Is this correct so far? If so, will the gov't then adjust my taxes to reflect the federal and provincial rates on my pension income, or can I expect a bigger tax break than that as I'm not using gov't services?
