Unit owners are legally bound to pay the monthly common expenses whether or not they are happy with the property management company and Board of Directors. If a unit owner does not make his or her monthly payments, the Corporation can register a lien against the unit for the amount owing, together with interest and legal costs incurred. Notification is also provided to the unit owner’s mortgage lender, which may pay the arrears on the unit owner’s behalf (usually resulting in default of the mortgage). If the unit owner or mortgage lender fail to pay the arrears, the Condominium Corporation can sell the unit to collect the amount owing. The Condominium Corporation may lien a unit within three months from the date of the non-payment of common expenses.
