Concerning the example you gave of perhaps a shift from a website to social media, as a communication person I would have a problem with that specifically, simply because you have a routine such that people know where to look and can reliably go to a website and find the information there, and not go to Transport Canada one day, Health Canada the next. Sure, put it on Health Canada, but be consistent. Always putting it on the Transport Canada site is something that I think makes sense.
I can certainly support Mr. Aubin's “and” versus the “or” on that basis.
