Highway Safety Code
(chapter C-24.2, s. 633.2).
1. Section 474 of the Highway Safety Code (chapter C-24.2) is suspended with respect to a flexible folding aerodynamic system installed at the rear of a road vehicle provided that, as shown,
(1)  no part of the system located at more than 1.9 m from the ground exceeds the rear end of the vehicle by more than 152 cm when extended;
(2)  no part of the system located at less than 1.9 m from the ground exceeds a virtual line connecting the following points when extended:
(a)  a point located at 1.74 m from the ground and 121 cm from the rear end of the vehicle;
(b)  a point located at the rear end and the lowest part of the vehicle bumper or, if there is no bumper, a point located at the lowest part of the rear end of the vehicle;
(3)  no part of the system exceeds the rear end of the vehicle by more than 30.5 cm when folded.

2. With respect to a flexible folding aerodynamic system installed at the rear of a road vehicle, the second paragraph of section 4.1 of the Vehicle Load and Size Limits Regulation (chapter C-24.2, r. 31) is suspended and replaced by the following:
“The same applies to the flexible folding aerodynamic system located at the rear of a road vehicle, provided that, as shown,
(1) no part of the system located at more than 1.9 m from the ground exceeds the rear end of the vehicle by more than 152 cm when extended;
(2) no part of the system located at less than 1.9 m from the ground exceeds a virtual line connecting the following points when extended:

(b) a point located at the rear end and the lowest part of the vehicle bumper or, if there is no bumper, a point located at the lowest part of the rear end of the vehicle;
(3) no part of the system exceeds the rear end of the vehicle by more than 30.5 cm when folded.
M.O. 2024-04, s. 2.
3. With respect to a flexible folding aerodynamic system installed at the rear of a semi-trailer of a road train, subparagraphs 3 and 4 of the first paragraph of section 3 of the Special Road Train Operating Permits Regulation (chapter C-24.2, r. 36) are suspended and replaced by the following:
“(3) the first semi-trailer has a maximum length of 16.20 m and a minimum length of 12 m, in the case of a type B double train, or 13.50 m in the case of a type A or C double train, the whole without taking into account the presence of a flexible folding aerodynamic system located at the rear of the semi-trailer, provided that, as shown,
(a) no part of the system located at more than 1.9 m from the ground exceeds the rear end of the vehicle by more than 152 cm when extended;
(b) no part of the system located at less than 1.9 m from the ground exceeds a virtual line connecting the following points when extended:
i. a point located at 1.74 m from the ground and 121 cm from the rear end of the vehicle;
ii. a point located at the rear end and the lowest part of the vehicle bumper or, if there is no bumper, a point located at the lowest part of the rear end of the vehicle;
(c) no part of the system exceeds the rear end of the vehicle by more than 30.5 cm when folded.
(4) the second semi-trailer has a maximum length of 16.20 cm and a minimum length of 12 m, without taking into account the presence of a flexible folding aerodynamic system located at the rear of a road vehicle and complying with subparagraph 3.”.
