Selling in Eastern Ontario: MLS Rules and Open Offers

Quick answer: Two sets of rules shape how an Ontario seller can market a home, based on public statements from the Canadian Real Estate Association and the Real Estate Council of Ontario. According to the Canadian Real Estate Association, the REALTOR® Cooperation Policy, in effect since January 3, 2024, requires a residential property that receives public marketing to be listed on an MLS® System within the local board's timeframe, capped at three days. According to the Real Estate Council of Ontario and published reports, Ontario's open offer rules, in effect since December 1, 2023, allow a seller to authorize a brokerage to share the content of competing offers, though the number of offers must be disclosed to each bidder. Both sets of rules leave real choices with the seller, and both are worth understanding before a listing agreement is signed.

Selling a home involves more than choosing a price. Before the first showing, a seller and a listing brokerage decide where the property will be advertised, who will see it first, and how competing offers will be handled if more than one arrives. Two sets of published rules sit behind those decisions, one set from the Canadian Real Estate Association and one from Ontario's real estate regulator. This note explains what each says, using only public sources, and it is general information, not legal advice.

Why these rules matter before listing

Sellers often hear terms such as "coming soon," "private listing," "office exclusive," and "open offers" in the first conversation with a brokerage. Each term describes a different way of controlling who sees a property and when. The rules covered here do not tell a seller what to choose. They set the boundaries inside which a brokerage can offer those choices, and they define what a brokerage must explain to the seller along the way.

That matters in Eastern Ontario in particular, where a listing can be a village home, a lakefront cottage, a hobby farm, or an acreage with a well and septic system. The same two rules apply to all of them, but the practical questions differ. A broader overview of the region appears in the Eastern Ontario real estate market guide, and this note focuses on the process rules that sit underneath any listing.

The REALTOR® Cooperation Policy

The Canadian Real Estate Association adopted an amendment to its REALTOR® Cooperation Policy that took effect on January 3, 2024. The core requirement is straightforward. Once a residential property receives public marketing, such as flyers, yard signs, digital advertising, or newsletters, the REALTOR® must list it on an MLS® System within the timeframe set by the local board, and that timeframe is capped at three days.

The amendment also added a duty of cooperation to the REALTOR® Code. Published summaries of the policy describe two seller-facing parts. First, the REALTOR® must explain the benefits of MLS® exposure to the seller. Second, if the seller chooses not to use the MLS® System, that decision is documented in writing, and the property then is not marketed to the public. These two parts are drawn from published summaries rather than from the full text of the policy, so a seller should confirm the exact requirements with the listing brokerage. Local boards enforce the policy through the existing Code procedures, which means the practical details can differ slightly from board to board.

The summaries also note that the policy applies to residential properties offered for public sale. Published exceptions include new construction in multi-unit developments, commercial properties, and rental listings. A seller should treat these summaries as a starting point and confirm the current wording with the listing brokerage, since policies of this kind can be amended.

What the policy does not ban

One point is easy to miss. The Canadian Real Estate Association has stated that the policy does not ban exclusive listings. The dividing line it describes is between "one-to-many" and "one-to-one" marketing. Marketing aimed at the public at large triggers the requirement to list on an MLS® System. Direct, individual communication between REALTORS® does not.

In practical terms, a seller who prefers limited exposure, for example for privacy reasons, can still discuss that option with a brokerage. What the seller cannot do is have the property advertised broadly to the public while keeping it off the MLS® System. The association has described the reasoning in terms of fairness to other REALTORS® and their buyers, who might otherwise miss the chance to submit an offer before a sale is arranged.

Each approach has trade-offs that a seller can weigh with a brokerage. Broader exposure generally means more buyers can see the property, while a limited approach can mean fewer showings and less public information. Neither the policy nor this note predicts which approach produces a higher price or a faster sale, and a seller should be cautious about any brokerage that guarantees an outcome.

Open offers under TRESA and RECO

The second set of rules concerns competing offers. According to published reports, since December 1, 2023, Ontario's Trust in Real Estate Services Act framework has allowed a seller to authorize a brokerage to share information about competing offers with other bidders. Published reports describe the earlier process, in which the content of competing offers could not be shared, as a blind bidding process.

The Real Estate Council of Ontario describes the current rules in its Bulletin 4.1. Three points stand out. The seller's brokerage must tell every bidder how many competing offers exist. The brokerage cannot reveal the content of those offers unless the seller gives explicit written authorization. And the brokerage can never reveal personal information about a bidder, or anything that would identify the bidder, regardless of what the seller instructs.

The seller keeps control. A seller may choose which parts of the offers to share, such as the price, the closing date, or particular clauses, and may change those instructions at any time, before or after offers arrive. When a seller does authorize sharing, the brokerage must provide the requested information to all competing bidders equally. The bulletin also states that a seller's agent should explain the benefits and risks of disclosure to the seller.

Buyers have a matching option. A buyer who does not want an offer's content shared can ask for a confidential submission, and the bulletin directs a buyer's representative to explain that flexibility so the buyer does not form unrealistic expectations. Open offers are therefore optional, and a seller who prefers the traditional approach is not required to adopt the new one.

What this means for rural properties

Rural sellers often ask whether farms, acreages, and waterfront properties are treated differently. The published summaries of the Cooperation Policy name exceptions for multi-unit new construction, commercial properties, and rentals. They do not name farms, hobby farms, vacant land, or acreage as exceptions. A seller of a rural residential property should therefore confirm with the listing brokerage how the policy applies to that specific property, rather than assuming an exception exists.

Rural properties also raise questions that sit outside these two rules but affect the same decisions. Buyers of acreage commonly look at well and septic condition, access, zoning, and land use limits, and those details influence how a property is presented. The page on acreage near Kemptville and North Grenville covers the land side, and evaluating a country estate and its acreage covers how house and land are considered together.

Waterfront and higher-priced properties often draw buyers from outside the immediate area, which can make decisions about exposure and offer handling more consequential. For background on how price relates to what a buyer is actually receiving, see what a luxury price is paying for.

The local board picture

Because the Cooperation Policy leaves the exact listing timeframe to each board, the board that covers a property matters. Rural Eastern Ontario is served by more than one board, and the boundaries are changing. On March 25, 2026, the Ottawa Real Estate Board announced that members of the Renfrew County Real Estate Board voted in favour of merging with it. The announcement stated that the official merger date was still being finalized and that the boards would work on aligning systems and ensuring continuity of services.

The announcement did not publish operational details, so this note does not describe any effect of the merger on listing timeframes or procedures. A seller in the affected area can ask the listing brokerage which board's rules apply and whether any transition steps are expected. Board-level market statistics for the region are compared in a separate note on rural Eastern Ontario board reports.

The decisions a seller actually makes

Put together, the two rules leave a seller with a short list of decisions. The first is the exposure decision: whether the property will be marketed to the public, in which case it goes on the MLS® System within the board's timeframe, or whether the seller prefers limited, one-to-one marketing through the brokerage. According to published summaries of the policy, a seller who declines the MLS® System has that choice documented in writing and the property is not marketed to the public, and the brokerage can confirm the exact process.

The second is the offer decision: whether to authorize the sharing of competing offer content, which parts to share, and whether to revisit that choice once offers arrive. The number of offers is disclosed to each bidder either way, and personal information about bidders stays private either way.

The third decision is timing. A seller can ask the brokerage to explain the sequence in advance: when the listing goes live, when offers will be reviewed, and how bidders will be told. Having that sequence in writing before the property is advertised reduces the chance of surprises later.

Questions to ask before listing

• Which board covers the property, and what is that board's timeframe for listing a publicly marketed property on the MLS® System?
• What forms of marketing count as public marketing under the policy, and what counts as one-to-one communication?
• If a limited approach is considered, how will that decision be documented, and what marketing is unavailable as a result?
• How does the policy apply to a farm, acreage, waterfront, or other rural property, given that published exceptions do not name them?
• Will competing offers be shared, which parts, and can the instruction be changed after offers arrive?
• How will the number of offers be communicated to each bidder, and when?
• What written instructions will the brokerage keep on file about exposure and offer sharing?
• Would a real estate lawyer review the listing agreement and offer documents before they are signed?

What these rules do not say

Neither rule sets a price, promises a result, or says that one approach sells a home faster. The Cooperation Policy does not say that MLS® exposure always produces more offers, and the open offer rules do not say that sharing offer content produces a higher price. They describe what a brokerage may and must do, not what outcome follows.

The rules also do not replace the listing agreement, board rules, or legal advice. Board-level procedures differ in detail, rules can be amended, and the published summaries cited here were current when reviewed. A seller with specific questions can raise them with the listing brokerage, the local board, or a real estate lawyer.

Frequently asked questions

Does a seller in Ontario have to list on MLS?

Not in every case. Under the REALTOR® Cooperation Policy, a residential property that receives public marketing must be listed on an MLS® System within the board's timeframe, capped at three days. According to published summaries of the policy, a seller who prefers not to use the MLS® System can decline, with that decision documented in writing, and the property then is not marketed to the public. The full policy text and the local board's rules govern the details.

Are exclusive or private listings banned in Canada?

The Canadian Real Estate Association has stated that the policy does not ban exclusive listings. It distinguishes between one-to-many public marketing, which triggers the MLS® requirement, and one-to-one communication between REALTORS®, which does not.

Can a seller share competing offers with other buyers in Ontario?

Yes, according to the Real Estate Council of Ontario, with the seller's explicit written authorization, and published reports place the start of the open offer rules at December 1, 2023. The brokerage must tell every bidder how many offers exist, may share only the parts the seller approves, and can never reveal personal information about a bidder. A buyer can also ask that an offer be submitted confidentially.
