141. No person may, without the authorization of the council of the municipality,
(1) destroy all or part of a recognized heritage document or object or demolish all or part of a recognized heritage immovable, move it or use it as a backing for a construction; or
(2) demolish all or part of an immovable situated on a recognized heritage site, or divide, subdivide, redivide or parcel out a lot on such a site.
Before ruling on an application for authorization, the council must obtain the opinion of the local heritage council.
A person performing an act described in the first paragraph must comply with any conditions the council of the municipality sets out in its authorization.
The authorization is withdrawn if the project described in an application submitted under this section is not begun within one year after the authorization is given or if the project is interrupted for more than one year.
If a project is interrupted, the withdrawal of the authorization does not prevent the municipality from obtaining an order under section 203.
