What happened

RealPage’s YieldStar algorithm is alleged to have enabled Canadian landlords to coordinate rental pricing by utilizing sensitive, non-public market data. The software has been accused of contributing to rent increases in non-rent-controlled units through purported collusion and artificial price inflation. Tenants have reported significant rent hikes, which they attribute to landlords' use of the algorithm.
