101. A person may, without the authorization of the commission, alienate, subdivide and use for a purpose other than agriculture a lot situated in a designated agricultural region, in a reserved area or in an agricultural zone, to the extent that that lot was being used or was already under a permit authorizing its use for a purpose other than agriculture when the provisions of this Act requiring the authorization of the commission were made applicable to that lot.
This right exists only in respect of that part of the surface of the lot which was being used for a purpose other than agriculture or for which a permit authorizing use for a purpose other than agriculture had already been issued, when the provisions of this Act requiring the authorization of the commission were made applicable to that lot.
