Would a company pension cheque?

be considered part of an estate. Father died two days prior to the monthly deposit. He is entitled to the cpp/old age and the pension cheque for the month of december. Is that money that would go to the estate to pay off bills, or is it like life insurance which does not go towards bills. There is a will leaving everything to 2 beneficiaries. There are outstanding visa bill and a line of credit. no ets other than the pension and a life insurance policy
