The main exception is a home held in joint tenancy, where a surviving co-owner already holds title through right of survivorship and the transfer to a buyer does not need probate at all. That exception does not apply to a home owned solely by the person who died.
Probate itself does not stop the marketing process. An executor can list the home, hold showings and accept an offer while the application is still before the Court of King's Bench, as long as the contract's possession date leaves enough time for the grant to arrive before closing.
Get the home priced correctly while that process runs rather than waiting until the grant arrives. Joel Dyck's hand-reviewed valuation accounts for improvements a previous owner made without a permit, so the estate has a defensible number from the day it lists.
