I hope you got your answer, but no, you do not claim it.
The estate pays taxes on it, if required.
The only way you would have used the money would have been as executor before renouncing the estate, or if you used it for funeral expenses and sent the bill to the estate. Sometimes a funeral home will bill the estate directly for funeral costs, sometimes they send the bill to the relative placing the order, who then effectively "bills" the estate after.
Funeral expenses are often paid / released from the estate before the entire accounting is finished.
Between the death (and final tax return) and disbursement to heirs, the estate is essentially considered a "trust", and results in the T3 forms / filing that is mentioned on the CRA site. This is because many estates take more than a year to wind up and close (hand over all assets to beneficiaries).
Generally, money from the estate disbursed to beneficiaries (especially non-spouses) has been fully taxed before you receive it.
