That is a very important question and has been probably for a few decades. People have recognized that international mergers pose significant challenges for domestic competition authorities, particularly in smaller jurisdictions. If you're the United States or Europe, you may have enough clout to deal with the mergers as you wish. For a smaller authority, such as the Canadian Competition Bureau, you have to co-operate.
I'm no expert on the mechanisms of co-operation. I know it's in the legislation that they are allowed to co-operate, but there are sometimes limits put on the degree to which they can co-operate and share information. Obviously, it's more sensitive in criminal matters than it would be in merger reviews. I can tell you that all international agencies that I know of are very seized with the need to coordinate.
One of the reasons the commissioner wanted some changes to our merger review was to put our system more in line with the Americans so that we weren't passing on mergers that the Americans were going to block. Sometimes you might like to free-ride on the others, but you want your own voice in these fights. I think we need to worry about that.
