Short answer: Ontario's MLS® is not one national database — it is a network of local real estate boards. Your listing normally appears on your home board. An MLS® Interboard Listing Upgrade adds your property to a second, neighbouring board so buyers and agents who search there see it too. It matters most when your likely buyer is searching from an adjacent area.

How MLS® boards work in Ontario

Each real estate board runs its own MLS® system for its geographic area. REALTOR.ca pulls listings from across these boards into one public site, but agents typically search their own board's system when working with buyers. If your property sits near a boundary, some of your best buyers may be working primarily on the neighbouring board.

When an interboard listing helps

  • You're near a board boundary and buyers commonly cross it.
  • Your buyer pool is regional — e.g. people relocating from a nearby city.
  • Your property type draws from a wider area (recreational, rural, or specialized properties).

If your buyers are almost all local to your home board, you may not need it. It is an add-on for reach, not a requirement.

Need buyers on another board to see it?

Ontario's MLS® is a network of local boards. The MLS® Interboard Listing Upgrade adds exposure on a board outside our home-board area.

How the upgrade works with List It

The MLS® Interboard Listing Upgrade is an optional add-on: $199, or $129 with the Ultimate Money-Back Guarantee Package. It extends your exposure to a board outside our home-board area, so a wider set of agents and buyers can find the property. You can learn more on the Interboard listing page and see current pricing on the packages page.

Interboard vs plain REALTOR.ca exposure

Every List It listing is on REALTOR.ca, which the public can search Canada-wide. The interboard upgrade is about the agent-facing board systems — making sure agents working the neighbouring board see your property in their day-to-day search, not just on the public site. For most sellers the home board plus REALTOR.ca is plenty; the upgrade is there when a second board genuinely widens your buyer pool.

Not sure if you need it?

A good rule of thumb: if you can name a neighbouring city or region your buyers are likely coming from, the upgrade is worth considering. If your buyers are firmly local, save the money. Start with a free listing and add the upgrade only if it fits.
