@daivey FYI, if only because I have really no idea of your expertise in these matters and you are only posting a news article that disturbs you.
@jaswest2754 - This is already in effect and has been as long as I remember but Canlii only publishes historical editions of the C.C.C. back to 2003, more later in this post..
@angryaudifanatic Because you stated you have a Law Degree and are an expert in H.T.A. matters (goes somewhat hand in hand with C.C.C. driving matters). Give your head a shake, you and the lawyer quoted in the article.
First off the new provisions specifically reference alcohol AND drug combination. The newest word included is "ceasing to operate a motor vehicle". In reality this has been in effect for alcohol as far back as when I was active, albeit under the provisions of Sec. 254(2) and they are still in effect, albeit the provisions of S. 254(2) reference a 3 hour limit. The police have always been able to demand a sample pursuant to 254(2) and there is numerous Case Law that references this and the reasons for why there is a limit. FYI - Experts have never been able to quantify results and extrapolating those results beyond a 2-3 hour window. As for the subject in the news article, there have been many an impaired driver arrested and charged as a result of drinking the night before and thinking they have "slept off" the alcohol in their system, when in reality they are still over the legal limit.
All this Legislation has done is bring the provisions of Sec. 254(2) into play within Sec. 253. Provisions that were always there but now with one less hour for the police to work with.
Yes, there will be Court challenges but I suspect the challenge will be with the difference in times and that it will be the 3 hour limit in Sec. 254(2) that may be challenged.
