The only option you have to enforce the Order of the Landlord and Tenant Board is the Sheriff. The Sheriff's fees can be recovered from the tenant when you are collecting on the Order received from the Board. One method of collecting is to file a Garnishment of Wages or Bank account which is done in Small Claims Court. You must have the information on where the tenant works to proceed with a garnishment. If you do not have this information you may have to go to a collection agency instead.
