Canadian Mutual Funds
Just read where Canada is now imposing a 15% withholding on all mutual funds distributions for non-residence shareholders.
Article suggested you should avoid these funds in your tax sheltered accounts since they do not pay tax and will not be able to claim the Federal credit for foreign tax.
I am wondering if this logic would not also apply to International Funds as well since other countries also imposed non-resident withholdngs.* Hence, keep your international exposure to taxable accounts.
