Okay, so I guess my real question is WHY?
Every FSS knows you're inbound. They have a strip on you. They even give you as traffic to other aircraft, even BEFORE you inform them of your presence. So why is this "warning, I'm inbound, hide the women and children" call even a requirement?
I suspect this came from some space dork in Ottawa to justify his existence.
Seriously. WTF? It's silly. Adds nothing to safety and ties up frequencies.
As an FSS, who happens to work some of the places mentioned(YTS, YMO), maybe I can clear up some of the confusion. Yes, we get a strip on IFR inbounds and outbounds. However, this strip only includes: who you are, what you are, where you're coming from/going to, and a CAATS estimate of your arrival time overhead the field. It does NOT include: your intended runway or approach information. The "heads up" calls 15 minutes out are nice because they help up plan out what we're going to need to do, lets us know if you have the ATIS information so we don't have to go into a long monologue of all the current information(weather, pireps, preferred runways, notams, rscs, etc) when you get handed over, and a more accurate ETA. When it's busy, we don't always get a point out from Centre, they give us one if they have time to, or if they're holding onto someone within 15nm.
You may not think it adds to safety, but the information we get on those calls is a huge help. Also, it closes a hole in the swiss cheese on the odd time that we DON'T get a strip on someone. In the event of a comm failure or the likes, we would have no clue that you're coming in otherwise. This happens more in YMO than it does in YTS. Has something to do with the connection between Winnipeg and Toronto that flight plans/itineraries opened by Winnipeg don't always populate.
If you have any further questions on the matter, I'll try my best to answer them for you.
