Yes, unfortunately with some foreign dividends you do.
What goes on in your Tax-free Savings account is exempt from local-based taxes (Capital gains, Dividends withholding tax, securities transfer tax).
However, in the case of a dividend paid by a dual listed company, where the dividends tax is withheld by the foreign company paying the dividend, those dividends are not exempt from the the dividends tax associated with them and will be deducted from your account.
The only good news, is that we take care of that on your behalf.
In your transaction history, you will see a line item with the dividends being paid into your account and then a further line item with the dividends tax being charged against them.
