As my colleague is looking it up, I would say that we of course have the information on which countries Canada has tax treaties with, and also on which countries are involved in the MLI.
With regard to the status of a country being, I think the term was, a “tax haven”, that's not a specific tax term. Some countries have what are known as blacklists. They have lists of countries they consider to be tax havens. There's a bit of vagueness. I don't know if there's a list of countries that definitively qualify or don't, and so it's difficult to answer that aspect of the question.
