The short answer to that is it's absolutely okay.
You raised flag protocol, and in terms of half-masting there is a set of federal guidelines that will apply to federal buildings, federal land. Provinces each have their own, and territories as well. Each province and territory will treat their provincial and territorial flag differently from the other provinces or territories, so they need their own set of guidelines. If you look at them across the country, they all fall in line together, and if you put them together they make sense.
One of the examples I can give you is on the half-masting policy. Both the federal government and provincial and territorial governments have, in some way, built in flexibility to their half-masting policies so that they can mirror the other and still be respectful of what's happening in one province, in one territory, while not necessarily changing the whole policy to do it. If there's an issue on half-masting in one area, we'll speak to the chief of protocol in that province or territory. There's a back and forth on things like that.
