I had the privilege of being vice-chair of the parole board for the prairie region earlier in my career, and I can tell you that my colleagues on the parole board and I were never shy about imposing abstinence conditions. It's a matter of policy and training for the parole board. Legislative authority isn't required.
Also, both institutional parole officers and community parole officers generally do a very fine job in discharging their responsibilities, in using their authorities and their discretion in terms of what kinds of breaches they want to bring to the attention of the parole board for review.
In that regard, I don't think this legislation is actually going to make an operational difference for the parole board. Those reviews are already done, and this legislation does not in any way fetter the discretion of the parole board to consider whether or not a positive drug screen is grounds for a revocation or a cancellation of parole. It's still highly discretionary.
