Since you are sharing the kitchen facilities with the tenants, the tenancies are not covered under the Residential Tenancies Act. The only law that may apply in this case is contract law. Since you did have a written contract and it specified that the tenant would have to provide a 60 days’ written notice to end the tenancy, you may be able to pursue him in Small Claims Court if you incur a loss of rent. However, you should try to re-rent the unit as soon as possible. If you need more advice on this matter you may have to consult with a lawyer or a paralegal.
