I don't believe so. They seem to have incident reports. The Office of the Correctional Investigator says that there were 3,532 incident reports involving visitors from February 2015 to April 2017, and 25% of those were positive hits on the ion scan. That seems to be the total sum of information that's available. I've done multiple requests for information and can get no better information than that.
On November 2nd, 2017. See this statement in context.
