No — an automated number and a professional’s opinion of value answer different questions.
Short answer
No. An automated online estimate is neither a REALTOR®’s comparative market analysis nor a professional appraisal. The Appraisal Institute of Canada describes its designated members as “Canada’s real estate valuation experts” providing independent appraisal services — an online tool has no inspection, no local market knowledge and no accountability for the number it produces.
Even CREA’s own professionally maintained national price benchmark needs over 15 years of sales data and statistical modelling to be trustworthy, and it still only produces a neighbourhood-level figure, not a specific property’s value. An anonymous online tool pulling from public sale records has far less to work with than that, and no way to account for your subject property’s actual condition, upgrades or defects. A CMA is a REALTOR®’s opinion, built with local MLS® access and a client relationship behind it; a professional appraisal from an AIC-designated member is independent and credentialed. An online estimate is neither of those things — it is a starting point, not a substitute for either.
CREA’s own guidance on AI-generated information is direct on this point: “REALTORS® must remain fully accountable for the information, advice and services they provide to clients”, tying that standard to the REALTOR® Code’s advertising rules on accuracy and claims. If you pass an online estimate to a client without your own review, you own that number the same way you would own any other representation you make to them — treat it as a conversation-starter, not as your CMA.
Most online estimates run on public records of past sales, refreshed on their own schedule — not on the market’s current direction. CREA’s own national benchmark edged up 0.1% month-over-month in its most recent statistics package, the first monthly increase since November 2024, after a long run of declines. A model trained on the declining trend can lag a turn like that by weeks, which is exactly the situation where a client relying on an old online number and your current CMA will disagree the most.
