One of the duties of an Executor is to file a tax return, or in some cases tax returns on behalf of the deceased. The Final Return covers any taxable events between December 31 of the previous year and the date of death, so this period could be from one to 365 days.
The CRA publishes a very useful guide called Preparing Returns for Deceased Persons (T4011). This is available at any Tax Services office or can be downloaded from the CRA website at: Preparing Returns for Deceased Persons.
The filing deadline for a Final Return is six months after the date of death or the normal filing deadline which is ordinarily April 30, whichever is later.
To cancel the passport of the deceased it should be returned to Passport Canada with a copy of the death certificate and a letter indicating if the cancelled passport should be destroyed or returned to you.
