Madam Speaker, I thank the hon. member for the work that he does on the justice committee. I know that he will bring questions like this to the committee, and I am sure the committee will be able to get experts in to address those.
In general, I would say, rather than focusing on the sentencing provisions, what we are looking at is zero tolerance, and to make sure that people who have any drugs in their blood or saliva are not behind the wheel. When we look at mandatory screening, keeping people off the road is better than repeat offences, and the aim is to stop the offences from occurring in the first place.
