I'll start, and then I may ask my colleague if there's an operational example that may reinforce what I'm going to say.
With the way the legislation is proposed now, “reasonable grounds to suspect” is for a constellation of facts that you have possession of, and it's at the very beginning of an investigation. You're still trying to link a criminal to a crime where there's a victim. The confirmation of service demand is simply about having enough facts, which you need to document and are disclosable in court, to say, “Do you service this person, yes or no?”
You get your answer, and then you build on that. There has to be investigative work done to support what you've already found out, in addition to any other investigative avenues you have, in order to get subscriber information to try to link somebody to the crime that you're investigating.
