This is a nearly impossible task at present. There is a shortage of all hard currencies in Trinidad retail banks. This means you have to find people who are selling their currency at black market rates. This will make your transactional charges very expensive.If you have a valid TT credit card with a high limit you can make purchases of crypto currency though a crypto exchange. Then sell your Crypto in Canada. The set up takes some time. That means you can buy up to your monthly card limit and pay the bank in TTD. But banks are a moving goal post these days, so there is no telling how long that will work.Good luck
