Can you claim withholding tax you paid on foreign investments?

Yes, you can generally claim withholding tax paid on foreign investments but the same is also subject to multiple other conditions.

Claiming the withholding tax paid on foreign investment is subject to a long list of other conditions such as the type of foreign investment, the country in which the withholding tax was deducted and the status of the double taxation avoidance treaty of that country with Canada. Additional conditions may also include the payment of withholding tax so deducted to the foreign government, a certificate for such payment and so on.
