Canada’s RRSP deduction limit sets the maximum deduction for yearly contributions to your RRSP, PRPP, SPP, or a spouse’s or common-law partner’s plan.
The tax agency generally based that limit on unused room, an earned-income amount capped by the annual limit, pension adjustments, reversals, and past service adjustments.
Generally, you could contribute to your RRSP, PRPP, or SPP until December 31 of the year you turned 71, with available deduction room.
For a 2025 return, qualifying contributions were made by March 2, 2026, and deductible amounts included current contributions, spouse-plan contributions, and unused prior-year contributions.
You could not deduct administration fees, trading fees, borrowing interest, capital losses inside an RRSP, or employer PRPP contributions; excess amounts >$2K triggered monthly tax.
