I'm thinking of anecdotal evidence only. Evan, I believe, keeps track of the reports from the DRE-trained officers.
Before I pass it over to him, you asked about standard field sobriety testing being tested in the courts. Some of the provinces, certainly Manitoba, have regulations under their highway traffic acts requiring people to do that. My understanding is that challenges to that have been unsuccessful, but that's a challenge to provincial administrative law. This is the Criminal Code. We'll have our own challenges, no question.
