I'd have to think about that, but I think “by regulation” in this provision, at the very least, would cause some confusion when it's read with the rest of the provision, because section 4.2 is a listing of the responsibilities. It's kind of a high-level list of responsibilities and authorities that the minister has to administer the Aeronautics Act and to enter agreements and things like that. Not all of those responsibilities can be fulfilled by means of a regulatory instrument, and you wouldn't necessarily want it to have to be done that way. Some of those responsibilities...it would make it very difficult to negotiate the agreements if everything had to be done by regulation.
I'm not sure what the intention was of “by regulation” at the end of that provision, but I don't think it achieves a goal that you would want to have.
The only other concern I have is with the wording itself. I think it really constrains the minister, because it says:
shall ensure that aeronautical activities are conducted at all times in a manner
There's no ability in that wording for him to do anything different, and “shall ensure” is really difficult wording to live up to.
