Municipal safety, housing and maintenance standards usually state that it is the owner’s responsibility to make sure that the property can be safely entered and exited.
The RTA does not address snow removal directly. It only says that it is the landlord’s responsibility to make sure that the property is kept in a good state of repair, is fit to live in and complies with health and safety standards. If you file an application to the LTB about snow removal, the member (adjudicator) would decide whose responsibility snow removal is.
If you live in a mobile home park or land lease community, the landlord is responsible for snow removal.
