Landlord’s Self-Help Centre can only provide summary advice on “most” landlord/tenant related questions from landlords. Unfortunately, as the nature of your questions is very specific to the history of your property, and the municipality in which the property is located, the “rules” vary from one municipality to the next. We will not be able to provide you with accurate and usable summary advice on your situation. You may have to deal with a lawyer specializing in municipal law to coordinate and access the information you are seeking. I imagine you have already dealt with the municipality staff directly, but it is a good idea to do so if you have not.
