They are not. Ontario has already promised to fully fund RER on the Stouffville and Kitchener lines.
That would mean the only difference between RER and ST then is the Heavy Rail down E
Every smart reader will recognize we are disagreeing only on semantics.
There are multiple interpretations of the terms, since RER can be a general plan of the whole GO upgrades, including express diesel trains. So the confusion can arise.
So to fix this confusion:
GLOSSARY -- for the purposes of the SmartTrack thread
"RER" -- pretending Tory never existed -- whatever original Ontario plan for frequent electric trains in the core segment of the Kitchener and Stoufville corridor, roughly between Bramalea through Unionville. We're of course, excluding the non-electrics, even though the RER umbrella often includes upgraded diesels.
"ST"/"SmartTrack" -- the Tory enhanced version of the said above RER plan
More accurately, "SmartTrack same thing as RER"
may be phrased,
if you prefer, as
"SmartTrack is a subset of the whole GTA RER plan. SmartTrack is the all-stop RER train that serves all stops in the core 416 segment of the Kitchener-Stoufville lines."
What this means is there won't be an separate all-stop RER electric train and all-stop SmartTrack electric train. That would make no sense.
Essentially, they are the SAME train, when we're specifically talking about the allstop electric rail beast they're planning to run in the core segment of Kitchener-Stoufville GO routing that the SmartTrack route overlaps.

Now, back onto topic.
The original RER plan was not planning to have the large number of infill stations. And we may very well have been getting electric locomotives rather than, say EMUs. Regardless, it's still a merger of RER/ST into a unified service that combines the best elements of each. Obviously, it's worth debating the large differences in the cost. Were we going to just get simple Exhibition-style platforms and electric-locomotive GO trains, plus maybe 2 infill stations? That's not really worth SmartTrack. The $8bn (for it to really make sense) would need to buy subway-style cars, great stations, good interchanges, subway-convenience, level boarding, a brand new routing (whatever is chosen).
But that's besides the point, since I don't like the Eglinton portion. Removing that (as well as the cost of infill stations that the Eglinton would have needed) could probably save many billions of dollars, and make the estimates far closer (e.g. Ontario original $3bn versus Tory-enhanced-minus-Eglinton $5bn), which would be easily explained in other SmartTrack elements such as the large increase in infill stations, especially if they were better than simple GO stations, considering the Eglinton stations would probably have needed to be underground and the interchange stations are incredibly complex.
Those few Eglinton stations that are underground, plus the interchanges at the endpoints of Eglinton crosstown -- could have ended up eating up $1bn total, the rest of the stations ~$1bn, then we've got roughly a $2bn+$3bn+$3bn math). Now if we eliminate Eglinton, the math becomes so much cheaper.
Obviuosly, we don't have all the answers yet, so speculation about $3bn through $8bn and what it could have funded (or not) is really speculative. But it makes a lot of sense that high quality subway-style level-boarding infill stations with GO stations redone into SmartTrack specific stations, would be stupendously expensive. That may not necessarily be what citizens want, or need, but would explain a large part of the cost differences, too.
That is exactly what I posted above -- the $8bn is only if Eglinton was built (AND of course, full-monty on all infills, new stations, interchanges, redo existing stations to level boarding, etc).
Obviously, we can save quite a lot of money here; I'm not disagreeing. But that is not the point. I was simply merely pointing out that Eglinton was a huge part of the $8bn cost, by showing the 2.6+2.6+2.6 breakdown example.
Regarding
specifically the allstop electric rail beast they're planning to run in the core segment of Kitchener-Stoufville GO routing that the SmartTrack route overlaps. Honestly, there
isn't going to be two separate kinds of electric trains doing exactly the same stops in the overlapping section.
