256.2. No permit authorizing a cadastral operation may be refused on the sole ground that the area or the dimensions of the tract of land do not allow it to satisfy the pertinent requirements of an interim control by-law or of a subdivision by-law in respect of a tract of land that meets the following conditions:(1) on 30 November 1982 or on the date preceding the date of the coming into force of the first interim control by-law of the regional county municipality, whichever date is the later, the tract of land did not form one or several separate lots on the official plans of the cadastre;
(2) on the date applicable under subparagraph 1, the tract of land was the site of a structure built and used in accordance with the by-laws in force at that time, if such was the case, or protected by acquired rights.
To be authorized, the cadastral operation must result in the creation of a single lot or, where the tract of land is comprised in several original lots, of a single lot for each original lot.
The first two paragraphs apply even if the structure is destroyed by a disaster after the applicable date.
