Canada Politics

Canada requires you to have a plan that makes you an asset to Canada (fair enough). Certain occupations in certain provinces are in need. Having a plan to start or invest in a business and hard proof that you have the capital to do so ($2M USD) is also a possibility. Having family in Canada and already having a written job offer or business plan helps. There is also the matter of the medical clearance and demonstration of proficiency in both English and French.

FWIW, Canada does not have a retiree visa, but many countries do.

France, Costa Rica, New Zealand look mighty good. Uruguay if you are looking for no entry visa requirement, no retirement visa income requirements, duty-free on your car and the ability to buy real estate as a non-citizen. Apartment with ocean views in Punta?
