HSR should not be viewed only as a noncommuter system -- France is proof -- Japan is proof
Britain is proof. Hitachi-built Class 395 Javelin trains run regional services using the infrastructure built for Eurostar. They are good for 140 mph, so they don't bog down the true TGV style trains heading for the Continent. And...they switch from pantograph to third rail en route.
Okay, it would be hard to interleave a slow GO bilevel stopping every three miles with a TGV, but something in between is possible. Certainly, regional services stopping at the main centers on the Ontario lines would coexist well with true HSR.
As to why KW and not the Brantford line ...trying to coexist with CN freight is not a wise strategy. The Dundas hill is a big obstacle. CN runs its freights at crawl speeds up that grade, often 10 mph or less. There are regular stalls, which blocks the line until a set of rescue power is dispatched to push the freight up to Copetown. So one track has to be assumed to be occupied by CN all the time. If you look at the current VIA schedules, even at 4 trains a day, one track is occupied by a VIA train a great deal of the time between Brantford and Bayview. Adding additional tracks in that area would be very costly.
The Stratford line has very light freight operations. The Limehouse grade is shorter and more benign than Dundas. Not having freights in the way means not crossing over, thus avoiding the problem that makes the Kingston Sub unworkable for fast passenger. This line is not really so much longer in mileage, at good high track speed the difference is only a few minutes.
