Who owns the home and who has to sign
Start with a title search. It shows every registered owner, how they hold title (joint tenants or tenants in common) and everything registered against the property: mortgages, lines of credit, liens, executions. Every owner must sign the listing and the sale.
Then look past title. Under Part II of the Family Law Act, a married spouse who is not on title must still consent to the sale of a matrimonial home, and a transaction without that consent can be set aside. An estate trustee needs a Certificate of Appointment before the land registry will accept a transfer. An attorney under a power of attorney for property needs the document itself, and the same spousal consent rules apply.
What your mortgage will cost to pay out
Ask your lender in writing for a payout statement. It sets out the principal, interest to the closing date, a per-day figure in case the date moves, any prepayment charge and the lender's discharge fee. A closed term usually carries a prepayment charge; the lender's own contract governs how it is calculated. The federal Interest Act limits the charge on certain mortgages by individuals once five years have passed since the mortgage was made, so ask the lender to show its calculation.
Some mortgages can be ported to a new home, which can reduce or avoid the charge. That is a question for the lender; we make sure whatever they agree to is reflected in the closing.
Timing the sale against your next home
If you are buying as well, the order matters. A same-day closing moves your sale proceeds straight into the purchase, but the purchase cannot close until the sale funds arrive, so keys come late in the day. A staggered closing, buying first and selling a few days later, needs a bridge loan from your lender, and lenders usually want a firm sale before they lend. A purchase conditional on your sale is the safest for you and the least attractive to a seller.
Whichever you choose, both agreements should be drafted with the other in mind. Closing dates, deposit amounts and what happens if one side is late all need to line up.
Tenants, permits and what follows the house
Some things travel with the property whether the buyer wants them or not. A residential tenancy passes to the buyer under the Residential Tenancies Act, 2006; you cannot end it because you are selling. An open building permit stays open until the municipality closes it, and a buyer's lawyer can find it. Rental contracts for a water heater or furnace bind whoever owns the home until they are assumed or bought out.
Each of these is manageable, but each is far easier to manage before a buyer's conditions are running than after. Tell your agent and your lawyer about them at the start.
The documents to gather now
Find the transfer or deed from when you bought, the survey if you have one, the current mortgage and line-of-credit statements, this year's property tax bill, building permits and inspection sign-offs, warranties and manuals, the rental contracts, and for a condominium the declaration, rules and latest budget. If part of the home is rented, add the lease and rent records.
Your lawyer will also need government identification for every owner and, where it applies, the will and death certificate, the power of attorney, or the separation agreement or court order that deals with the home.

Questions people ask
Can I sell if my spouse is not on title?
Not without their consent, if you are married and the home is a matrimonial home. Section 21 of the Family Law Act requires the other spouse to join in or consent, unless a separation agreement or court order has dealt with the home. A sale made without consent can be set aside.
Do I need a lawyer before I have an offer?
Not by law, but Ontario transfers are registered by lawyers, so you will need one to close. An early review of title, consents and the listing agreement costs little and prevents the problems that most often delay closings.
What if I owe more than the home is worth?
The lender must be paid in full before it will discharge the mortgage, and your lawyer cannot transfer clear title without that discharge. The shortfall has to come from your own funds or from an arrangement with the lender made before closing.
Can I sell a home under a power of attorney?
Yes, if the power of attorney for property allows it and is in effect. The attorney signs in that capacity, the land registry requires the document, and the matrimonial home consent rules still apply if the owner has a spouse.
Does the buyer take over my mortgage?
Usually not. Most sales pay the mortgage out on closing. A buyer can assume a mortgage only with the lender's approval, and the lender may keep you liable unless it releases you in writing.
