A cooperative database system used by real estate brokerages to share property listings with each other. In the GTA, MLS is operated by TRREB (Toronto Regional Real Estate Board). When your property is listed on MLS, it becomes visible to every TRREB member agent and is syndicated to public-facing sites like Realtor.ca, giving it maximum market exposure.
Why It Matters
MLS is the single most powerful marketing tool for selling a home. Over 90% of buyers begin their search online, and MLS feeds the major real estate websites. Selling without MLS means significantly reducing your exposure to potential buyers and likely leaving money on the table.
Real-World Example
Your agent lists your townhouse in Scarborough on MLS with professional photos, a 3D virtual tour, and a detailed description. Within hours, the listing appears on Realtor.ca, and dozens of agents receive automatic alerts for their buyer clients who match the criteria. Over the next five days, 42 showings are booked through MLS's scheduling system, and you receive 8 offers on offer night.
Ontario & GTA Context
In the GTA, MLS is operated by TRREB and covers the entire Greater Toronto Area, including Toronto, Peel, York, Durham, and parts of Simcoe County. TRREB's MLS system is one of the largest in Canada, with over 70,000 member agents. TRREB rules require that listed properties appear on MLS within a specified timeframe, limiting how long a property can be marketed exclusively off-MLS.
How It Works in Practice
Ensure your MLS listing has professional photography, accurate square footage, and a compelling description. The first 48 hours on MLS generate the most interest, so your listing must be presentation-ready from day one. Your agent manages the MLS listing, but you should review it for accuracy before it goes live.
