Social posts for every listing, automatically

Generating a listing's social posts automatically is straightforward. Publishing them automatically is where the failures are. A public post and a direct message are governed differently, and the "just sold" post has a consent matrix of its own.

Key takeaways

  • • CASL applies to messages sent to an electronic address; the CRTC states that a wall post is not captured while a social messaging system message is.
  • • Where CASL applies: consent, identification and an unsubscribe link valid at least 60 days, processed within 10 business days, with penalties up to $1 million for an individual.
  • • Ontario requires agent and brokerage identification to be visible on the profile and applies its advertising rules to personal accounts used for business.
  • • A sold post needs the seller's consent before completion and the buyer's after, and both parties' consent to mention price or terms.

Automate the generation of listing social posts, never the publication. That single rule handles almost every risk in the workflow, because the things that go wrong — a wrong price, a missing consent, a post about a property that just fell out of escrow — are all caught by a person spending fifteen seconds looking at a queue.

The second thing worth knowing before building anything is that a public post and a direct message sit under different laws in Canada, and most people building automation do not know that.

Where CASL starts and stops

Canada's anti-spam legislation applies to a commercial electronic message sent to an electronic address. The CRTC's frequently asked questions on CASL define an electronic address as an email account, a telephone account, an instant messaging account, and any other similar account — and then draw the line that matters here: a typical advertisement placed on a website or blog post would be excluded, and a Facebook wall post would not be captured, while messages sent to other users through a social media messaging system would be.

So the listing post on your business page is not a commercial electronic message. The direct message you send to twelve people telling them about it is. The regulator also notes that CASL applies to SMS and other messaging to mobile devices, but not to live voice or automated telemarketing calls to telephone numbers, which are governed by the unsolicited telecommunications rules instead.

Where CASL does apply, the CRTC sets out three requirements: obtain consent, provide identification information, and provide an unsubscribe mechanism. The unsubscribe link must remain valid for at least 60 days after the message is sent, and a request must be processed without delay and no later than 10 business days after receipt. The maximum administrative monetary penalty per violation is $1 million for an individual and $10 million for a business, and directors and officers can be personally liable where they directed, authorised or acquiesced in the violation.

The consent distinction is the part most worth getting right before automating anything, and the sister firm covers it in implied versus express consent under CASL, with the mechanics in unsubscribe mechanism requirements.

What the real estate regulators require of the post itself

Ontario applies its advertising rules to social media without modification. RECO Bulletin 5.3 states that while social media platforms may seem less formal, the same advertising requirements apply; that proper identification of the agent and brokerage must be readily visible or accessible on the account profile through the available fields and profile graphics; and that an agent using an account for both personal and professional purposes must ensure both the account and each message relating to trading in real estate comply.

It also handles the character-limit problem head on: where a platform limits content, a verifiable statement can be advertised with an easy-to-find link pointing to a full explanation. That is the sanctioned way to carry a qualification a caption cannot hold.

British Columbia is slightly more permissive on mechanics and identical in principle. BCFSA's advertising guidelines require the name of the related brokerage on the profile screen when social media is used for business purposes, and note that each individual post is not required to contain it — while all platforms used to market services or properties must follow the same guidelines as print advertising.

Sold posts have their own consent matrix

The "just sold" post is the single most common compliance failure in real estate social media, and Ontario publishes the answer in a grid. RECO Bulletin 5.4 sets out that advertising a property as sold requires written consent, that the consent must be clear and include the dates on which it takes effect and expires, and that whose consent is needed depends on timing and content.

Before the transaction completes, advertising that a property is sold requires the seller's consent, whether the advertisement is placed by the seller's brokerage or the buyer's. After completion, it requires the buyer's consent, again from either side. And in every case, adding the price or other terms of the deal requires both the seller's and the buyer's consent.

An automation that generates a sold post from a status change in your CRM will get this wrong unless the consent state is a field it can read. Which is the argument for the queue.

The trademark rules a template will break

If you are a CREA member, the REALTOR® mark has rules that a caption generator will not follow. CREA's plain-language summary gives three: first use must be in capitals followed by the registered symbol; the mark identifies membership rather than a job title; and business and promotional material displaying the mark must, where possible, carry a trademark statement. Its guidance for advertisements works through what that means when space is short, and its trademark page explains why the marks are policed at all.

Ontario adds the permitted-descriptor list in Bulletin 5.2, including the point that REALTOR®-based descriptors are limited to CREA members in good standing and that short forms and nicknames must not be used in advertising. Put your compliant signature block into the template as fixed text rather than letting the model write it each time.

The pipeline that works

Trigger: a listing status change, not a calendar. Status is the fact; a schedule is a guess.

Generate: three caption variants from the verified listing description only, with the brokerage identification and any trademark statement inserted as fixed text.

Gate: a queue a person clears. The check is four items — is the status still true, is the consent in place and unexpired, is every fact in the caption in the listing, is the identification present.

Publish and log: record where each post went and the consent end date, because Ontario requires content to come down when consent expires and to be removed promptly on request.

Common questions

Can I schedule a month of posts in advance?

You can schedule the drafts. Publishing a month ahead means publishing facts you have not checked on the day, and listing status, price and consent all change inside a month. A queue reviewed twice a week gets the same time saving without that exposure.

Does a direct message campaign need an unsubscribe link?

If it is a commercial electronic message sent to an electronic address, then yes — consent, identification information and an unsubscribe mechanism are all required, and the CRTC expects the link to stay valid for at least 60 days and requests to be processed within 10 business days. Direct messages through a social platform's messaging system are the case the regulator gives as captured, which is why the public post and the DM should be treated as two different systems.

Can I post about another agent's listing?

Only with permission obtained through the agent representing the seller or tenant, and any post featuring that listing must credit and include the name and contact information of the originating brokerage. The same bulletin treats using another party's imagery or verbatim property descriptions without written consent as a breach, and calls plagiarism and scraping unethical.

Where does this fit with the rest of the marketing?

Social distribution is one channel of a listing's launch. The video half is covered in AI listing video without a videographer, and the copy it all draws from in writing a property description with AI.
