The tenant’s fridge stopped working and the tenant lost some food. They’ve provided grocery receipts and expect to be reimbursed for lost food.
There is no provision in the Residential Tenancies Act that that states the landlord is responsible to pay for the tenant’s lost food when the fridge malfunctions. The landlord has a duty to fulfill his maintenance obligations and deal with the situation as quickly as possible.
There is no specific way to prohibit a tenant from obtaining appliances. It can be stated in a lease agreement but even then it would be difficult to enforce. Basically unless the appliance has caused damage or is causing some electrical or plumbing problem the landlord does not really have much recourse.
