I was a beneficiary for a pension. Do I claim it as pension or death benefits

Here's some information on being a beneficiary:

Inheritances themselves (i.e. assets at time of death) are generally not taxable in Canada, but any income earned by the estate is. Beneficiaries have to report income distributed to them, which are generally reported by the estate on a T3 (Statement of Trust Income Allocations and Designations).
