This is actually just modern drafting technique.
If you look at the existing provision dealing with this, you see that it refers to six sections of the Criminal Code, the Aeronautics Act, and the Railway Safety Act federally. There is not a mention of any shipping act or anything like that. The modern practice is to ask what this is to be used for and not to try to tie it around. All of this information is connected with drugs or alcohol, so I would imagine that adding the drugs or alcohol back in isn't a problem whatsoever. Trying to list the legislation would be an impossible task.
