Yes, these signs are still present in a number of the HEP-1 cars. I have seen them in Skyline cars and Park cars for sure, and at least one of the ex-CP HEP-1 coach cars. I think I may have seen one in a Chateau sleeper bathroom as well, although I'm not sure.
Having said that, all of VIA's HEP-1 cars DO have retention toilets, and have for many years now. The signs are simply a left-over from years ago when the cars dumped on the tracks. Yes, they were originally built to dump on the tracks, as recall that these were Budd cars built in the 1950s. They have all been retrofitted at a later date with retention tanks. For whatever reason, they haven't bothered to remove many of the "Do not flush toilet while train is in station" signs. I think it's kind of a neat bit of nostalgia for those of us who understand, although I admit it must be confusing for some passengers!
