Coordination algorithmique minant la concurrence sur les marchés

RealPage's YieldStar algorithm recommends rental prices to competing Canadian landlords using shared market data — enabling what critics call algorithmic price coordination without the explicit agreements that competition law was designed to address.

Multiple Canadian institutional landlords, including CAPREIT and Minto Group, have used YieldStar's revenue management system. The algorithm ingests confidential data from participating landlords — occupancy rates, lease terms, local market conditions — and outputs price recommendations. Because competing landlords feed data into and receive recommendations from the same system, the result is price convergence that functions like coordination without any direct communication between competitors.

The documented rent increases are substantial: 7–54% annually for properties using the system, often exceeding Ontario's rent control guidelines. The Competition Bureau of Canada launched an investigation in August 2024, but discontinued it on November 10, 2025, finding that revenue management tools were not sufficiently widespread in Canada to substantially harm competition. A class action lawsuit filed in Canadian courts alleges algorithmic price-fixing. In the United States, the Department of Justice reached a settlement with RealPage in November 2025, effectively banning its core business model of pooling nonpublic landlord data for rent recommendations.

The structural challenge for Canadian competition law is that the Competition Act's conspiracy provisions require proof of an "agreement" between competitors. When firms independently adopt the same algorithm that uses shared data to converge on supra-competitive prices, the traditional concept of agreement may not apply. This is not a gap that can be fixed by better enforcement of existing law — it requires legislative adaptation to a form of market coordination that did not exist when the Competition Act was drafted.
