Slips are prepared by your employer, payer, administrator or financial institution. You should receive most of your slips (including your T4, T4A, and T5 slips) and receipts by the end of February. However, T3, and T5013 slips do not have to be sent before the end of March.

If you use CRA My Account, you may be able to view your tax slips online.
