If your tenant is moving out without a doubt, you should not serve him with a notice of non-payment of rent. As of September 1, 2021, landlords can file an application for arrears of rent 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.

Once you have obtained an order from the LTB, there are several ways you can try to enforce that order including garnishee of wages, garnishee of the bank account or recovery using the services of a collections agency.
