412.21. Every person who carries out the demolition of an immoveable or causes it to be carried out without a permit or in contravention of the conditions of the permit is liable to a fine of not less than $5 000 nor more than $25 000.
In addition, the by-law contemplated in section 412.2 may require that person to restore the immoveable so demolished to its former condition. Where the offender fails to restore the immoveable in accordance with the by-law, the council may cause the work to be carried out and recover the costs thereof from the offender, in which case section 412.16 applies, with the necessary modifications.
