Every home in Ontario must have a working smoke alarm on every storey and outside all sleeping areas.
Homeowners: It is the responsibility of homeowners to install and maintain smoke alarms on every storey of their home and outside sleeping areas.
Landlords: It is the responsibility of landlords to ensure their rental properties comply with the law.
Tenants: If you are a tenant of a rental property and do not have the required number of smoke alarms, contact your landlord immediately. It is against the law for tenants to remove the batteries or tamper with the alarm in any way.
