51. (1) A land surveyor carrying out boundary operations agreed to by the parties or ordered by the Court shall place one or more boundary markers to mark the boundary of any land or property which he is surveying, or to show the course of any division line.
(2) The form, dimension and nature of the boundary markers placed by the land surveyor shall be established by regulation of the Bureau.
(3) Any person, other than a land surveyor, who places a boundary marker contemplated in subsection 2 is guilty of an offence and is liable to the penalties provided in section 188 of the Professional Code.
(4) When, because of local conditions, it is impossible to place a boundary marker in accordance with subsections 1 and 2, the land surveyor shall enter such fact in his minutes; he shall fix the boundaries and describe his operations by designating the streets, neighbouring properties and other fixed objects in such manner that any other land surveyor may by means of such minutes repeat the operations and determine the boundaries, points, lines and other details; he may also fix the boundaries and describe his operations with respect to a local system of rectangular coordinates detailed in the minutes.
