Days on market is the number of days a home has been listed for sale before it sells. In Toronto, the Toronto Regional Real Estate Board (TRREB) tracks two versions of the number, and the gap between them tells you something the headline stat hides.
The first is listing days on market, or LDOM. It counts from the day a specific listing goes live to the day the property sells. If a seller cancels that listing and relists the home next week, the counter starts over at zero. Property days on market, or PDOM, works differently. It counts from the first time the property was listed by the same seller and brokerage, no matter how many times it has been relisted since. PDOM cannot be reset.
Relisting is common in Toronto. Sellers relist to refresh a stale listing, to change price without showing a visible cut, or to switch offer strategies. That is why the two averages diverge. Through mid-2026, TRREB's Market Watch reports showed listing days on market across the GTA averaging in the low 30s, while property days on market ran into the mid 40s. A gap that wide means a meaningful share of listings are on their second or third attempt.
For buyers, PDOM is the better negotiating signal. A listing showing 12 days on market might belong to a home that has actually been for sale for four months under different MLS numbers. Your agent can pull the full listing history. For sellers, days on market works like a pricing report card. Well-priced Toronto homes tend to sell within their first few weeks, and the longer a listing sits the more buyers start to wonder what is wrong with it, a dynamic explained further in what happens if your home doesn't sell.
The number also works as a market thermometer alongside months of supply. When average days on market falls, the market is heating up. A sustained rise usually signals the opposite. And if a listing you are watching disappears and reappears, the move is usually visible in its listing status.
