The RRSP deduction limit statement on NOA for 2022 does not show any unused amount available for deduction in 2023 return. My concern here is contributions for Jan-Feb 2022 as well as Jan-Feb 2023 that weren't previously claimed in 2022 and which I would like to claim now in my 2023 return. I have the tax receipts for those contributions but why my NOA does not show these unused contributions. Can I still change the amount that wasn't claimed in 2022 return even though they are not reflected in the deduction limit statement for the year 2022. Any help would be highly appreciated please!
