7.1 (a) The horizontal and vertical alignment of the road approach and the road over the grade crossing shall be smooth and continuous within the safe stopping sight distance. 

(b) The horizontal alignment of the road over the tracks shall be straight extending beyond the outside rails for a distance equal to the length of the design vehicle. 

(c) The profile and elevation of the grade crossing surface and the rest of the road shall match and safely accommodate the maximum road operating speed in accordance with the design standards of the Geometric Design Guide.

7.2 Subject to the conditions in subsection 7.1 and except to provide for vehicular grade crossings of superelevated track as required in subsection 7.4, the maximum gradients for roads at a grade crossing shall not exceed the following:

1. ratio of 1:50 (2 per cent) within 8 m of the nearest rail and 1:20 (5 per cent) for 10 m beyond, at unrestricted grade crossings for vehicular use;
2. ratio of 1:50 (2 per cent) within 8 m of the nearest rail and 1:10 (10 per cent) for 10 m beyond, at any other grade crossing for vehicular use;
3. ratio of 1:50 (2 per cent) within 5 m of the nearest rail at grade crossings for pedestrian or cyclist use only; and
4. ratio of 1:100 (1 per cent) within 5 m of the nearest rail at grade crossings specifically identified as a route for persons using assistive devices.

7.3 Roads in grade crossings constructed before(CIF), shall conform to the following:

1. in the case of a public grade crossing for vehicular use, the ascending or descending gradients of roads shall not exceed a vertical to horizontal ratio of 1:20 (5 per cent), unless authorized by the National Transportation Agency prior to January 1, 1989 under the Railway Act, or the Minister of Transport for Canada after that date, under the Railway Safety Act; and
2. in the case of other grade crossings, the ascending or descending gradients shall be safe for the use to which the grade crossing is put. 

7.4 At vehicular grade crossings incorporating superelevated track, the difference between the gradient of the grade crossing surface on superelevated track and the gradient of the adjacent road shall not exceed the limits specified in the Geometric Design Guide. 

7.5 The width of the travelled road lanes and shoulders at the grade crossing surface shall not be less than on the road approaches. 

7.6 A grade crossing where the maximum railway operating speed exceeds 15 mph shall be constructed as specified in Figure 7-1, with the angle of intersection between the road and the track of: 

1. not less than 70 nor greater than 110 degrees without a grade crossing warning system; or 
2. not less than 45 nor greater than 135 degrees with a grade crossing warning system.

7.7 The surface of the road approaches and that part of the road forming the grade crossing shall be maintained in good condition for the maximum road operating speeds, including clearance of snow and ice or adequate treatment with abrasives, in a manner to permit vehicles: 

1. to stop safely within safe stopping sight distance of the grade crossing; and 
2. to start from a stopped position at the grade crossing and proceed safely over the tracks.
