I think it's more a case of if the property isn't being occupied at all the RTB will act, I doubt they would go as far as looking to see who was living there though the landlord must provide the person's name in the declaration. If the landlord was just using the family needs as an excuse and re-let the property, a new tenant with a different name claiming Rent Tax Credit could trigger an investigation.What if the person who moves in is a family member? How would a tenant know every member of a landlords family especially any individual named on the SD?
The landlord is obliged to offer it back to the former tenants.Also, if a family member did move in and was there for less that 12 months but then had to leave - only temporarily - for work or medical reasons, what happens then?
The challenge with the RTB is the unpredictability, in this case they upheld the eviction .
