As of September 1, 2021, section 88.1 of the Residential Tenancies Act allows a landlord to file a claim for damages with the LTB within one year from the date the tenant is no longer in possession of the rental unit. The tenant must have moved out of the rental unit on or after September 1, 2021. However, you will need to know the tenant’s new address so you can send them a copy of the documents. We cannot advise on whether you can take action against the property management company, as we can only advise on the landlord and tenant issues. You might have to speak to a lawyer or paralegal about this issue, as it would probably come under contract law.
