Bill 51: Rent Stabilization Act, 2025

This bill directly impacts residential landlords and property management companies operating in Ontario — from individual landlords renting out a single unit to large corporate landlords managing hundreds of apartments. Day-to-day, landlords will need to file statements with the Landlord and Tenant Board every time they enter a new lease or change rent, maintain their properties to strict repair standards (with no defence based on effort alone), and will no longer be able to raise rent to market rates between tenants. Small landlords who self-manage a handful of rental units will face significant new administrative burdens around registry filings, while larger property management firms will need to update their systems and processes to ensure compliance across all units. Landlords who fail to file required statements can be blocked from filing their own applications at the Board and face fines of up to $1,000 per day for non-compliance with maintenance orders.
