Madam Speaker, I thank my hon. colleague for the statement in terms of constitutionality. The purpose of this legislation is to ensure that people are deterred from thinking they can consume any level of drug or alcohol and think it is reasonable to get behind the wheel of a car. The intention, in terms of the mandatory breath screening, is to change the thought processes of individuals who think they can get behind the wheel of a car and to ensure that police officers have the opportunity to increase their ability to catch people who are impaired by drugs. That would increase by 50%, according to the evidence we have.
In the House of Commons on May 19th, 2017. See this statement in context.
