Mr. Speaker, yes, indeed, in going through this, I read the concerns from those who said that on the grounds of civil liberties this would be intruding on constitutionally protected rights. I think, on balance, the courts will find this justifiable because of the threat of drunk driving, and as the hon. parliamentary secretary has mentioned, it is clear that the stop must be legal.
There is a concern once we start having the legal threshold for that stop adjusted downward in order to create more opportunities for testing people at the roadside. On balance, I agree with it. I think the fact that we have advice from Professor Peter Hogg is very reassuring. He is the country's leading constitutional law expert, and I studied from his textbook when I was at law school so I hold him in the highest regard.
However, I am talking about not so much whether it is challenged in court but about how it is applied day to day. That is going to be something that I hope we will be aware of as we take the bill through committee.
