Let's say, for example, that you had the question of deciding whether or not a breathalyzer test were something to be sought, and there were a separate provision in the code that said, “If you smelled alcohol on somebody's breath, they had bloodshot eyes,” or other observational signals for how the signs of a driver look.... If you were to say that, you would use “reasonable grounds to suspect” to enable the officer to order a breathalyzer test at that point.
Then, if there were another, separate provision in the code, which talked about observational driving, and if you saw the car swerving from side to side, it would be important to use the same “reasonable grounds to suspect” in both cases, and not have one be “reasonable grounds to suspect” and the other one “reasonable grounds to believe” in order to order the breathalyzer test.
That may be a bit convoluted, but, essentially, you're coming to the same point. You have reason to suspect that the driver might be impaired, and you have different ways of assessing that. One would be, for example, the physical signs—such as they're slurring; their eyes are glassy, etc.—and one would be how you observe their driving. It would make no sense, in that case, for you to have determined that one would be “reasonable grounds to suspect” and one would be “reasonable grounds to believe”. Would you agree with me in that case?
You would never recommend to the Minister of Justice to put two different standards in the bill for essentially the same type of activity that causes an officer to want to order a breathalyzer test.
