Mr. Durocher mentioned the mandatory notification process with respect to mergers. At the bureau we have obviously a general ability to gather our own intelligence. That may come from other work we are doing. We've been increasing our intelligence function at the bureau to make sure we are kind of keeping our finger on the pulse of what's happening in competition in markets.
Certainly complaints are a big factor in terms of what we may be looking into. There are specific ways for us to detect some of the conduct that was mentioned to you earlier, such as cartels conduct, which can be one of the most difficult to detect. I would let my colleague Mr. Guay add anything he may wish to, but in that area there's a specific program for immunity, under which we try to encourage members of a cartel to come forward, because it is a very difficult area for us to detect.
All of these things combined are how we try to identify anti-competitive behaviour.
