Under "Income" from the left side menu --> choose T-slip --> Foreign Slip --> Fill the proper Boxes by indicating the country, type of income (there are different boxes for pensions from the United States or other), and you will find a box for Foreign Tax Paid.
Some pension income from some countries is subject to tax exemptions if the countries have entered into tax treaties with Canada. The list of the countries can be found in this link:
