If there is a valid will you only need to follow the testator's directions.
If there is no valid will, or no will at all it will go through the administration process and the residue will be split equally between his surviving children (this would not include any amounts from life insurance, rrsps or other instruments that have a named beneficiary).
I do probate work full-time and would be more than willing to answer some questions if you have any.
