Multiple Listing Service (MLS)

May 22, 2025


What is the Multiple Listing Service (MLS)?

The Multiple Listing Service (MLS) is a cooperative database where Canadian real estate agents list properties for sale, enabling wide visibility and information sharing.

Why the Multiple Listing Service (MLS) Matters in Real Estate

MLS is the primary tool used by REALTORS® across Canada to market homes, share listings, and find properties for buyers. It aggregates comprehensive property data including:
  • Listing price
  • Home features
  • Photos and virtual tours
  • Neighbourhood data
Only licensed real estate professionals who are members of a board affiliated with the Canadian Real Estate Association (CREA) can post listings on MLS. The system fosters transparency, comparability, and competition in the marketplace.

MLS offers benefits for both buyers and sellers:
  • Sellers gain broad exposure to qualified buyers
  • Buyers can access detailed, up-to-date listings
MLS listings also power popular public-facing platforms like REALTOR.ca, where consumers can search properties nationwide.
Understanding MLS is key to navigating the Canadian real estate market effectively, whether buying or selling a home.

Example of the Multiple Listing Service (MLS) in Action

A real estate agent lists a detached home in Ottawa on MLS. The listing appears on REALTOR.ca and attracts dozens of viewings within days.

Key Takeaways

  • Central database for property listings.
  • Accessible to licensed real estate professionals.
  • Powers REALTOR.ca and public search platforms.
  • Enhances visibility, comparability, and trust.
  • Vital tool for real estate marketing and discovery.

Canada Is Building More Homes (But Fewer Of Them Are For People To Own)

Canada Is Building More Homes (But Fewer Of Them Are For People To Own)

It’s no secret that developers have lost faith in Canada’s once-booming condo sector. It’s also no secret that the rental segment has emerged as something of a saving grace for the housing market, with new and pivoted projects alike benefiting from government-backed incentives. But a new report from Desjardins underscores that the broad volley from condo to rental is not a risk-free trade-off.

Authored by Economist Kari Norman, the report points out while there have been around 130,000 rental housing starts recorded over the last four quarters, condo starts have slipped below the 50,000-mark for the first time since the 2009 global recession.

MOD Developments Files Plans For 40-Storey Rental At Randolph Theatre

MOD Developments Files Plans For 40-Storey Rental At Randolph Theatre

Rendering of 736 Bathurst Street/Diamond Schmitt

Real estate insolvencies have been a dime a dozen over the past few years, but 736 Bathurst Street is proof that, sometimes, they come out of the other side. A new development application from MOD Developments and Montez Corporation proposes a 40-storey purpose-built rental tower for the site at the southwest corner of Bathurst and Lennox streets, which is currently operated by the Randolph College of Performing Arts. In a previous life, the two-storey venue was the Bathurst Methodist Church, built in 1888.

As mentioned, the site has a bit of a turbulent history. In 2024, ONE Development listed the property for sale after drawing up preliminary plans for a 49-storey mixed-use tower. Less than a year later, lender Timbercreek Mortgage Servicing Inc. successfully petitioned the Ontario Superior Court for a receivership order after alleging the owner had defaulted on its mortgage. Court-appointed monitor MNP then marketed the site through a formal sales process before it sold, paving the way for MOD and Montez's current proposal.
