Motor Vehicle Safety Regulations — 111
111 (1) Any mirror referred to in this section that is installed on a vehicle shall (a) have a stable support; (b) be adjustable in the horizontal and vertical directions; (c) be a unit magnification mirror, except in the cases referred to in subsection (6), paragraph (13)(b) and subsection (16); (d) be free of sharp points or edges that could cause an injury to an occupant of the vehicle or to a pedestrian; (e) except in the case of a System B mirror installed on a school bus that has a forward control configuration, be installed so that the driver’s field of view through the mirror is not obscured by the portion of the windshield that is not wiped by the windshield wipers or by any opaque portion of the vehicle structure; and (f) in the case of an outside rearview mirror, have no greater protrusion beyond the perimeter of the vehicle than is necessary to meet the field-of-view requirements for the mirror prescribed in this section. (2) A rearview mirror referred to in subsection (7) or (11) or paragraph (26)(a) shall be capable of adjustment from within the occupant compartment of the vehicle. (3) The average reflectance of a mirror referred to in this section shall be determined in accordance with SAE Standard J964, Test Procedure for Determining Reflectivity of Rear View Mirrors (June 1992). (4) A mirror referred to in this section that is a single reflectance mirror shall have a reflectance level of at least 35 per cent. (5) A mirror referred to in this section that is a multiple reflectance mirror shall have a daytime reflectance level of at least 35 per cent and a night-time reflectance level of at least 4 per cent. In the event of electrical failure, the mirror shall be adjustable, either manually or automatically, to a reflectance level of at least 35 per cent. (6) An outside rearview mirror referred to in paragraph (7)(b) or subsection (26) or (27) that is installed on the side of the vehicle opposite the driver’s side may be convex if (a) its reflective surface area is equal to or greater than the reflective surface area that a unit magnification mirror must have in accordance with that paragraph or subsection; (b) its average radius of curvature is not less than 890 mm (35 inches) and not greater than 1 800 mm (71.5 inches); and (c) the radius of curvature at any point does not deviate by more than 12.5 per cent from the average of any five radius-of-curvature measurements made on its reflective surface at least 6 mm (0.25 inch) from the edge of the image display. Passenger Cars and Three-wheeled Vehicles SOR/2003-272, s. 13 (7) An inside rearview mirror shall be installed on every passenger car and three-wheeled vehicle and shall, under the conditions prescribed in subsection (8), (a) provide the driver with a field of view to the rear that (i) is not less than 20° measured horizontally rearward from the projected eye point, and (ii) extends to the horizon and includes a point on the road surface not more than 60 m (200 feet) directly behind the vehicle; or (b) where the inside rearview mirror does not provide the field of view to the rear described in paragraph (a), be accompanied, on the side opposite the driver’s side, by an outside rearview mirror that has not less than 90 per cent of the reflective surface area of an outside rearview mirror installed pursuant to subsection (11). (8) For the purposes of subsection (7), the vehicle shall be on a level road surface and loaded with the lighter of the following loads, calculated on the basis of the driver and each occupant weighing 68 kg (150 pounds): (a) a driver and four other occupants, and (b) an occupant in each designated seating position. (9) A field of view to the rear described in paragraph (7)(a) may be partially obscured by seated occupants or head restraints. (10) An inside rearview mirror referred to in subsection (7), if situated in the head impact area, shall, when the reflective surface of the mirror is subjected to a force of 400 N (90 pounds) in
