Anyway, to answer the OP: no, I didn't hear it was Reserve Recognition day and didn't see any sign of an announcement by DND amidst the other announcements this week.
Now going against the grain here, and self-pronouncements of big 'nads aside, since the day's not really talking about people working in a DND facility where everyone wears a uniform, I can see as a Reservist it has the potential to be weird. In fact, I imagine even our crusty Reg F brethren would find it noteworthy if they walked into a Timmies or Best Buy or whatever and were served by someone in uniform.
Not that a little weirdness should stop anyone (Hey! possibly a future unit motto there, if you put it in Latin) , and IMHO the public seems much more welcoming in general, definitely more than in the '80s.
