At a job I had a while back I would look up properties and view the mortgages, liens, HELOC's, etc. Often they would be paid in full, and marked as discharged, without being removed from the property registry. Removing the loan isn't required, at least in my non-Ontario province. Find out if you even need to do it by calling the land titles office. See if you can bring the discharge papers down and do it yourself.
Congrats!
