Madam Speaker, I do not think we will find a parliamentarian in this House who does not agree that we need to do everything possible to discourage and, hopefully at some point, eliminate impaired driving. As one of my colleagues said the other day, driving is not a right, it is a privilege. The right of people to peacefully and safely drive on our roads must take precedence over any other person's right to drive while impaired.
On the other hand, as legislators, we have a responsibility to make sure that this legislation is very carefully calibrated. The Supreme Court has told us that in R. v. Oakes and other cases.
My questions to the minister are on this new legislation around cannabis. A number of people are suggesting that a reading of two nanograms of THC per millilitre of blood may not indicate present impairment, particularly with chronic users of cannabis, maybe medicinal users, who use cannabis every day. Does the minister believe that measurement is an accurate measurement of present impairment?
Second, I am led to believe that many experts say we do not yet have proper screening devices that can prove true impairment. Does she have any concerns that by adopting those standards, we may be giving criminal records to Canadians who are using cannabis, as her government is going to legalize—
