Originality.ai finds 37% of Canadian real estate listings likely use AI

Originality.ai says a new review of 72,047 Realtor.ca listings found that 37% of Canadian real estate listings are likely AI-written, with the highest rates in Calgary, Moncton and Hamilton. The findings raise fresh questions about disclosure as AI becomes more common in property marketing and consumer-facing listing copy.

Why it matters: - Homebuyers and renters often rely on listing copy to make one of the biggest financial decisions of their lives. - Originality.ai’s findings suggest AI is already shaping public-facing real estate descriptions at scale, without clear disclosure in many cases. - The study points to a growing transparency gap as AI tools spread across property marketing.

What happened: - Originality.ai analyzed 72,047 active Realtor.ca listings across 20 Canadian cities. - The company found that 37% of Canadian real estate listings were likely written by AI. - The research was recently covered by The Globe and Mail. - The full Originality.ai study is available online: More information.

The details: - Calgary had the highest share of likely AI-written listings at 70%. - Moncton followed at 63%. - Hamilton came next at 62%. - Montreal and Quebec City were notable low outliers, at 7% and 9% respectively. - Sale listings were more likely than rental listings to contain AI-written descriptions. - 42% of for-sale properties were flagged as likely AI-generated. - 22% of rental listings were flagged as likely AI-generated. - Originality.ai found likely AI-written listings more often used common real estate phrases such as “exceptional,” “ideal,” and “nestled.”

Between the lines: - The data suggests AI use in real estate is uneven across markets, with some cities far more exposed than others. - That spread may reflect different brokerage practices, local competition, or varying comfort levels with AI-assisted marketing. - Madeleine Lambert of Originality.ai said the concern is not that realtors are using AI tools, but that public-facing listing content may be changing without consumers realizing it.

What's next: - Originality.ai says the findings support clearer disclosure standards for AI use in public-facing real estate content. - AI tools are expected to keep expanding across real estate workflows, including marketing, lead generation, listing descriptions and virtual staging. - Originality.ai says it will continue research into how generative AI affects digital content, publishing, search, education and consumer trust.

The bottom line: - AI-written real estate copy appears widespread in Canada, and the biggest issue now may be transparency rather than technology itself.
