I don't know why Barbados is our third country. I don't know whether that's true, but I'll defer to you on the accuracy of it. In the case of investments from Canada in Barbados, I suspect that in many cases it's a case of using Barbados as a holding company for investments in other jurisdictions.
As I think I mentioned before that that doesn't result in any loss of Canadian tax. If Canada invested directly in any of 93 countries we have tax treaties with or any of the countries we have tax information exchange agreements with, which I think adds another 25-or-so countries, the profits would all come back to Canada tax-free. It thus doesn't impact the tax in Canada at all.
In many cases, investments might be made in Barbados because they're not adding an extra layer of tax; you're not being double-taxed or facing increased taxation compared with what you would have paid if Canada had invested directly in those countries.
