The process allows the minister, if he determines there are public interest considerations, to ask a person or a group of persons--a committee, for example--to investigate what those public issues may be. That opportunity would allow the public to come forward and explain what the impacts--through air, rail, or whatever--may be on their communities.
It also allows for other members of the industry. For example, if you have something happening in rail, it could affect ports, or it could affect one of the passenger rail lines. It allows for all those concerns to be brought forward. Right now that mechanism does not exist at all.
