How taxes work with a Canadian pension in Belize?

My understanding is that you won't pay Belizean taxes but depending on what services or connections you still have to Canada you will pay Canadian taxes on any income or pensions. CPP and OAS are payable outside of Canada as long as you have spent your working years in Canada and made annual contributions to CPP.  Or CPP will pay out whatever the amount calculated based on your contributions.  OAS is paid outside of Canada as long as you lived in Canada for at  least 20 years after you turned 18.

If you are a "snowbird" and staying in Canada 6 months out of the year you still have to pay Canadian taxes, but you can stay out of Canada permanently - you retain your citizenship and pay no taxes in Canada on your pensions or CPP/OAS.  When or if you move back to Canada you may be subject to a waiting period to qualify for provincial benefits like healthcare etc.
