Starting September 21, Ontario renters face shorter eviction notice periods and new rules under amended Residential Tenancies Act. Renters have seven days to pay missed rent before eviction filings, and "persistent late payments" are defined as three late payments within six months. Landlords giving 120 days' notice to end tenancy for personal use no longer owe compensation. Tenants must pay 50% of arrears before hearings to raise issues. Renoviction rules require landlords to provide renovation updates or face compensation claims.
