I'm not sure whether you've had an opportunity to look at paragraphs 28(2)(a) and (b) of the act. From my perspective, reading in light of those would seem to indicate and cause some confusion, because there it is already stated exactly what kinds of businesses they can undertake. I would suggest this is redundant, except, of course, if you want to amend that section.
This could seriously compromise the existing activities in support of port operations, including activities of mutual benefit between, for instance, ports and municipalities. For instance, the Quebec Port Authority actually did some work in lead-up to the 400th anniversary—the Quebec birthday, in essence—and other things. My understanding is that the Saint John Port Authority has worked with the municipality sometimes. This would eliminate any opportunity for that.
