The thing about Central is that being so closely tied to the Mount Royal Tunnel makes the fact of it's existence one of those "OTL is actually kinda weird and longshot" situations. By all rights it never should have happened. With that said, in a more European like scenario with stronger build out, yeah, I absolutely adore the concept of Windsor being replaced with a second tunnel under Central...
Truthfully, I was more thinking that the Bell Centre is built above the tracks and Windsor stays in business, and as part of post-war developments that Central and Windsor are fused into one station, allowing the East-West corridor through Windsor to gain a tunnel to Place Viger, thus allowing Montreal to have a criss-cross arrangement, with trains west to Kingston and Toronto and east to Quebec City using the former CPR lines (as well as Exo's Saint-Jerome, Vandreuil-Hudson and Candiac lines) to use Windsor, while trains north to Ottawa (and those to Mirabel, which if it were me would be made into Montreal's only airport, as the land Dorval sits on could IMO be put to much better use) and south to Sherbrooke (and, ideally, to New York City) use the former Central Station and Mount Royal Tunnel. Of course, this also would likely result in an EXO line along the former CPR along the east end of Montreal Island, connecting with the existing Mascouche line at Montreal East and following the north shore of the St. Lawrence.
- parochially Federal Avenue in Toronto is my highest priority
- and it's obvious follow up of the hockey arena over Union's train shed
- in my mind this also incorporates a version of New City Hall matching the aesthetic, but there's a lot of options there, and I narratively rather like the things that come of indecision with regard to a new City Hall and courthouse.
- how does it sound if Federal goes in while a Victoria Square (as it was then known) is an established but undefined concept with the result that:
- Old City Hall stays city hall, and eventually gains an architecturally matched tower in the courtyard
- the square becomes the new court house
- something is built early post-war, is generally disappointinga and is being replaced by ~2020
There are a few problems here. I mentioned that the building of the grand buildings along Federal Avenue is unlikely due to wars and economic issues until after WWII, and here you'd likely just end up with the bank towers along Federal Avenue than along Bay Street. That said, if you can make it happen by 1920 and then see Toronto build a whole bunch of Art Deck buildings along Federal Avenue, I'd be all for it, and as a few that existed IOTL that would face the new avenues could be kept, I can see Federal Avenue's grander buildings being retained and merged into the later developments.
The Air Canada over the Union Station trainshed is obvious. I had the idea (in grand Toronto-Is-Awesome plan for my TLs) of having the Arena built as the high-speed train system for the Detroit-Quebec City corridor is building built, and the plan not only includes the arena but also includes turning Union Station into a double-deck station, with sizable ramps up to the second level from the east and west to allow Via Rail trains (and other regional services and any long-distance ones) to use the top deck of the station, dedicating the lower one for GO Transit, who would then build OTL's Bay and York Concourses for their use, while Via trains are accessed from a concourse above the second level, with the Air Canada above that. In addition to that, the TTC would build a dedicated streetcar terminal below the existing station, accessed by streetcar ramps off of Front, Lower Bay and the Esplanade, directly connected to the adjacent Union subway station. At the same time, my plan called for the Gardiner to be buried from Parliament to between Bathurst and Strachan. and where the OTL arena is would instead be a major bus terminal, accessed not only by ramps from Lower York and Yonge (Bay is probably too much of a ramp for this) but also from the Gardiner Expressway directly into the Terminal.
With regards to Old City Hall, the problem there is that the original one took so long to build that within a decade of its being completed it was too small, and once the city rapidly grows (and Metro Toronto becomes a thing) the space problem would be that much more acute. The courthouse is going to have an easy place to go once the Armories move to Moss Park in any case so I'm not too plussed about that, but I'd ideally like to keep the Registry Building if possible. Maybe that's what happens - Victoria Square goes at the head of Federal Avenue with Osgoode Hall to the West, the Registry Building at the top of it and City Hall to the East, but the uproar about preservation of Toronto's past leads to the Land Registry Building becoming rebuilt as part of the project, with City Hall to the east of it. Maybe the building proposed in the 1920s is built instead:
And this building is what becomes the Courthouse, with the OTL Court House site becoming another building in the 1930s as part of a proto-WPA plan for Canada, while Victoria Square becomes a much more landscaped and interesting place than the expanse of concrete of OTL.
- nationally is saying I want to avoid privatization of the big crown corporations concrete enough?
Some of them, I really wish that hadn't happened either, particularly Canadian National Railways and Petro-Canada, both of which if well managed could be a sizable source of funds for Canada that doesn't involve taxation of any sort.
- If not I'm going to go with a two part answer of building the Georgian Bay Canal and changing... something about the transcontinental build out to avoid the extreme over building and collapse on their respective sides of WWI
The thing is, I'm pretty sure the buildout was kinda inevitable unless something happens to force the CNoR and GTP to work with each other. Maybe both face financial problems way earlier and as a result they are forced together, with the CNoR handling everything west of Winnipeg and the GT handling everything east of there. At the time, the CPR was weak in Ontario and Quebec and nowhere in the Maritimes and the Grand Trunk held a virtual monopoly on freight traffic in Ontario.
- REALLY big picture, I'm in support of most things that get Canada a larger population earlier, doubly so those that create an earlier focus on the west coast
- even without getting into wholly Canada Wank territory it would be REAL nice for the border to be at the Columbia River
- significant Indian immigration to the west coast in the 19th century really is one of those ideas that I keep coming back to
For that to happen you pretty much need to get Canada to send a lot of people west a lot earlier, before the Americans can forge the Oregon Trail and fill up both the Williamette Valley and the shores of the Salish Sea. As for Indian immigration, I'm not sure how you'd make that one work with the racial attitudes of the time, though one thought that occured to me was for America's growth westward to be slowed down and then once the Potato famine hits Ireland like a ton of bricks Britain instead develops a system of shipping lots of Irish westwards across Canada. Maybe the War of 1812 leads to America expelling as many First Nations people as possible, and Canada takes them in in huge numbers and uses them to assist Canada's westward expansion. They start by forging Manitoba by the 1830s and then they keep on going, and once the Famine happens the British quickly send them to Canada and then get them to go further west. They reach BC by the 1850s, and when the Yakima War happens the Irish Canadians intervene to assist the local first Nations, leading to the border being defined by the Columbia River and British Columbia being everything north and west of it. The War also results in Canada's independence and the building of the Canadian Pacific Railway earlier than OTL. The tribes and Irish form an alliance with each other that forces the British (who need them to keep the Americans from occupying the coast) to treat the First Nations peoples better, first in BC and then across the entire country.
