Although this is an unpopular opinion, personally I don't think that all-day GO train to Hamilton is a priority given the capabilities and service patterns of the Lakeshore West line. An all-stops trip to Union Station from Hamilton would currently take about 85 minutes which is far worse than the current #16 express bu
Not 85.
West Harbour Trains already sped up to be almost as fast as offpeak #16 express today! It's
only 64 minutes (06:09->07:13 Union) and
67 minutes today (16:02->17:09 Hamilton) for the two fastest West Harbour trains. All current and future West Harbour trains go express. Although not all West Harbour trains are this fast, they compactly vary from 67 minutes to 70 minutes -- all faster than Downtown GO trains. And
ridership is currently surging.
Also, the train is expected to become faster. The
September 2019 Metrolinx Blog for Hamilton says "
Our customers will be happy to hear that this will improve journey times through the area ". Also, in the current GO Expansion Business Case, the hourly allday 2way trains skip Appleby and Bronte too, speeding things up more. (Though I think it should skip Clarkson and stop at Port Credit for interchange with Hurontario LRT). Sub-60 minutes is technically possible.
Figure 1: The express nature of the hourly allday West Harbour trains (red=diesel, yellow=electric) and Niagara trains.
Now, when they electrify, the allstops are faster because of EMU acceleration/deceleration. The 15-min RER trains (that takes 40 minutes to Burlington), when extended to Hamilton, would probably only add 10-15 minutes extra (for a 55 minute trip).
Yellow = electric (circa year 2028), see 45 minutes allstop to Burlington.
For year 2041, when Metrolinx expects 15-min frequency to Hamilton, it is expected to be the extension of the electrified lines. There is a good question of electrifying Hamilton on freight lines, but that can come in many forms
-- Electrification of freight thanks to future climate-change accords/legislation etc.
-- Or Battery operation when crossing freight gaps
-- Or Rail-to-rail grade separation to jog the Metrolinx track to the opposite side of freight tracks
-- Combination. Diesel to Downtown GO, electrified to West Harbour GO
By year 2041, the West Harbour trip would be only about ~50-to-55-minutes, relative to the 45-minute Burlington benchmark that they want to do by year 2028. It is also possible other upgrades along Lakeshore West, will also speed up Burlington to approximately 35-40 minutes, making possible the 45-minute Hamilton EMU train commute.
My map is based on the actual Metrolinx documents, Metrolinx 2041 (full network map) and GO Expansion Business Case (Page 45 onwards).
Also Metrolinx just recently raised the priority of West Harbour -- currently, West Harbour is undergoing a surge of ridership just by doubling trains. Based on what I am currently witnessing on the ground, I think West Harbour will be one of the top5 fast-growing ridership stations on the GO network for at least two or three of four of these fiscal years: FY2020, FY2021, FY2022, FY2023 -- videos below.
Today the fastest West Harbour train is now more than 5 minutes faster than Downtown GO trains, and this is expected to speedup a bit more, once signals on that new third track over Desjardins are fully active. The track is connected now, but the signals still need to be fully commisioned. The GO Expansion Business Case uses a 68 minute value, but that number is already beaten today (67 minute).

...West Harbour in well under an hour has already been achieved with a sufficiently express train
My 2015 Pan Am GO express train ride of lore -- actually
zoomed past Burlington only 30 minutes after departing Union, (plus
reaperexpress data) even with only the 90mph rail speed limit (143mph max). My actual trip Toronto Union to Hamilton West Harbour was only 47 minutes. This is a good demo of the potential to beat the #16 Express with future corridor capacity/speed/electrification upgrades. Even if the future EMU was still allstop to West Harbour, it would still be less than an hour, thanks to EMU fast re-acceleration after stops. The service plan of future Hamilton 15-minute service, as of yet undetermined, may theoretically also include express EMUs.
...The GO EMUs (Burlington 2028, Hamilton 2041) may have a 200kph max speed.
In some parts of Europe is 200kph-rated EMU commuter trainsets -- The Stadler KISS that Metrolinx
famously use in pictograms is a 200kph electric train! There's even a pictogram of a Stadler KISS at Confederation GO station. This may not be anytime soon, but -- imagine. Even if Metrolinx does not choose the Stadler, most of the EMUs that Metrolinx is considering all have a faster max speed than the GO locomotives, with a few of them around 200kph-ish max. This open doors to gradually speeding up the railroad.
...And after that, is possible high speed trains. (50-year window)
Ultralong Term: Strategically, there is a long-term desire to electrify to the US border eventually. If the USA electrifies the Empire Corridor (Buffalo-New York) in 50 years from now. We could have Acela Express equivalents coming to Toronto in 2041, with a stop at West Harbour GO. Current GO trains are 90mph but the speeds could someday be upgraded to 125mph on some parts of Lakeshore West for 2041 in theory. As early as 2028, there'll be a 45-minute allstop to Burlington. And not all EMUs have to be allstop (Burlington in 25-30 minutes). The high speed trains would have multiple stopping plans including nonstop to border, one or two stops (i.e. Hamilton, Oakville), and multistop (i.e. Union-Oakville-Burlington-Hamilton-Niagara) -- much like the service plans of TGV, Taiwan, China, etc. -- and double as long-distance commuter trains as they already do in those countries. Varies by country, but I
rode one of those in Taiwan, unassigned seating, 20min frequency, missed my train, hopped onto next, ticket was not tied to any specific train, and it was just like hopping onto a 300kph GO train. Saw many commuters mixed in with the recreational travellers. This won't happen by 2041 I am sure, but certainly by the end of this century -- and this is yet another reason why West Harbour probably will get catenary before Downtown GO.
...If only one Hamilton route is electrified, it will probably be West Harbour and not Downtown GO
Strategically, West Harbour will be far more important to electrify for all the above reasons. If you combine express stopping plan and 200kph, Union to West Harbour becomes a 30-minute ride including having to slow down after Burlington on the CP tracks. That makes Hamilton-thru-Niagara trains quite much more bearable. It could be that Downtown GO gets the old hourly diesels, and West Harbour gets 15-minute allstop trains (55-min to Union), which would be far faster than a #16 on a 2041-extrapolated-congestion QEW. CN won't let it happen now, but eventually they'll have to capitulate under increasing climate-change-law pressures of the future decades (cheaper to permit catenary happen than not) -- then you'll see cats popping above the freights or adjacent tracks later this century.
...There's lots of time between now and 2041 to make trains faster than bus
By 2028, we'll already have an EMU that's ready to speedup to 200kph. While Lakeshore West is rated 90mph (143kph) at the most, it doesn't have to stay that way till 2041 especially if we have unused speed sitting around in an EMU we've already purchased. Plenty of time to upgrade Lakeshore to support that speed, to make it easily beat the #16 Express by a wide margin (Consider in 2041, the QEW and 403 will be WAY more congested). Now, imagine, we may have an express EMU that goes express Union-Burlington, that goes allstop after Burlington, for stops between Burlington and Niagara Falls, with about 35-40 minutes Hamilton, and 1h20min to the US border, if the Lakeshore West is slowly upgraded to 200kph standards where it makes sense by 2041.
...
Climate change legislation will probably accelerate funding for this
The next 20 years is going to increase pressure against freeway expansions. Only small climate-change dominoes would need to fall between now and 2041 to suddenly fund upgrades. That is more sustainable than 403/QEW expansions. Also, due to corridor constraints, it is easier to speedup West Harbour than Downtown GO.
