REALTOR® and MLS® Trademarks on Your Canadian Agent Website

Short answer: In Canada, REALTOR® and MLS® are registered trademarks controlled by CREA, so your website must write them exactly that way, use them only in the right context, and include a trademark statement. MLS® describes a co-operative selling service, never a database, so "search the MLS®" is wrong while "search MLS® listings" is fine. On top of CREA's rules, your provincial regulator sets advertising rules; in Ontario, RECO requires your brokerage's registered name to be clear and prominent on every agent and team site.

Why Canadian agent sites get this wrong

Most website templates and IDX plugins are built for the US market, where "MLS" is a generic term. CREA's own legal counsel has written that nearly every website they review uses the MLS® mark incorrectly, and puts it down to exposure to American marketing. In Canada, MLS® is registered, so the same wording that is harmless in Texas is a trademark problem in Toronto.

Do and don't: the REALTOR® mark

Based on CREA's guidance for members:

Write it in capitals with the ® symbol: REALTOR®. CREA allows a few exceptions, but capitals plus ® is the safe default.
Use it to show membership: "Priya Shah, REALTOR®" is acceptable. Adding a job title ("Priya Shah, Sales Representative, REALTOR®") is CREA's preferred option.
Add a trademark statement wherever there is room. CREA says websites have room, so it expects one there. Accepted statements include: "The trademarks REALTOR®, REALTORS®, and the REALTOR® logo are controlled by The Canadian Real Estate Association (CREA) and identify real estate professionals who are members of CREA."

Don't

Use REALTOR® as a job description. CREA's example: "My job is a REALTOR®" is a misuse; "My job is a salesperson. I am also a REALTOR®" is correct.
Write "Realtor", "realtor" or "realtors" in headings or meta titles because they look cleaner. The form rule applies to your SEO titles too.
Let non-members use the mark. Only CREA members may.

Do and don't: the MLS® mark

CREA's MLS® rules are stricter than its REALTOR® rules.

Wording	OK?	Why
"I provide MLS® services"	Yes	Refers to the co-operative service
"Browse MLS® listings in Kingston"	Yes	Listings offered through the service
"Search the MLS® System of [your board]"	Yes	Names the board's system correctly
"Search the MLS"	No	Treats MLS® as a database, and no ®
"Coming soon to MLS®"	No	Implies a database
"Mls listings"	No	Form rule: M, L, S capitalized, ® immediately after, no exceptions

Add the MLS® trademark statement. CREA says only one wording is accepted: "The trademarks MLS®, Multiple Listing Service® and the associated logos are owned by The Canadian Real Estate Association (CREA) and identify the quality of services provided by real estate professionals who are members of CREA."

Getting listings onto your site: DDF®

REALTOR.ca DDF® is CREA's managed service for sharing listings with websites. CREA's DDF® page describes several feeds, including:

Member Website Feed: your own and your office's listings on your personal website.
National Shared Pool: share your listings with other brokerages and display listings from the pool on your site.
Franchisor feeds: for brand websites.

DDF® has its own Member Policy and Rules, and CREA publishes technical documentation for developers. Your web developer works from that documentation, but you're the one who agrees to the rules, so read them. Your local board's IDX or VOW feed is a separate route with separate terms; which one you use depends on your board and what you want to show.

Practical points to settle with your developer:

How often the feed refreshes, and how sold or expired listings are removed.
Whether required attribution (listing brokerage, data provider notice) appears on every listing card and detail page.
That listing pages are crawlable for SEO without copying descriptions you have no right to reuse.

Provincial advertising rules: Ontario as the example

CREA's rules sit alongside provincial law. In Ontario, the Real Estate Council of Ontario (RECO) administers the Trust in Real Estate Services Act (TRESA). Its advertising bulletins are direct about websites:

Brokerage name on everything. Bulletin 5.1 says all advertising must include the name of the brokerage, and agents may not advertise unless the brokerage is "clearly and prominently identified". The name must match the one registered with RECO, with "brokerage" or "real estate brokerage" alongside it.
Your registered name, not a nickname. Short forms and nicknames must not be used.
Permitted terms. Describe yourself with a term the legislation allows, such as real estate agent, salesperson or broker.
Team sites are brokerage sites. Bulletin 5.3 says websites featuring an individual agent or a team are all brokerage websites, and one of the most common complaints RECO receives is a brokerage name that isn't prominent enough.
Consent for testimonials and sold data. Photos and names of happy buyers need written consent; so do property-identifying photos or sellers' names with a sale price.
No scraping. RECO calls plagiarism and scraping unethical; using someone else's images or verbatim descriptions needs written consent.
Claims must be verifiable. Comparative claims, sales volume and awards need the basis, source and date.

Other provinces have their own regulators and rules, for example the BC Financial Services Authority, the Real Estate Council of Alberta and the OACIQ in Quebec. Check yours before launch.

Site setup checklist

Header or top bar: brokerage name as registered with RECO (or your regulator) plus "Brokerage", clearly visible on every page.
Agent name as registered, with a permitted term.
REALTOR® and MLS® written correctly across pages, meta titles, alt text and URL slugs where they appear as words.
Footer: both trademark statements.
Listing feed under a signed DDF® or board agreement, with required attributions.
Written consent on file for testimonials, client photos and sold-price content.
A page or footer link to your brokerage's contact details and complaints process.
A yearly review, because regulator bulletins change.

FAQ

Can I use "realtor" in my domain name?

CREA's Trademark Manual covers domains and firm names, and it treats the mark strictly. Check the manual or ask your board before registering one; a neutral domain avoids the question.

Do I need the trademark statements on every page?

A site-wide footer satisfies "where possible" in practice, because it appears on every page.

Can my team brand be bigger than the brokerage name?

Your logo can be prominent, but in Ontario the brokerage must still be clearly and prominently identified. If a visitor could think the team is the brokerage, it's not prominent enough.

Is an IDX search widget a problem under these rules?

The widget is fine; the wording around it matters. Label it "Search MLS® listings", not "Search the MLS".
