Couldn't provision be made to add a possible branch operation to the Ontario Line? Maybe off at Gerrard Station have double storage tracks. Then in the future, continue those tracks as a branch line along Dundas Street (St. Patrick Boulevard), maybe joining back together in the west end and continuing going up Jane Street.

Not sure. The drawback of branching is a lower frequency of each branch. Lower frequency means lower capacity. Lower capacity may be OK for outer sections, but we want highest capacity in the central section.

Everyone from downtown (south of Eglinton) says that the subway is full by the time it reaches them. Lower capacity in the outer sections most definitely would not be ok - it would just mean the train is even more full when it reached the merge.

In the above suggestion, especially if the line makes it to Seneca College - would be completely full south of Sheppard if it had only half the frequency because it had to accept a branch at Gerrard.

I'll bet any bridges over the Don River and valley (both Riverdale and Leaside) will be built based on the lowest bidder. Nothing artistic about it. Unlike this transit bridge in Jerusalem.

Too true. The trillium extension in Ottawa is crossing the supposedly pretty Airport Parkway with ugly off the shelf girders and concrete. That's Ontario.

One branch would serve Queen and Osgoode Stations on Line 1, the other branch would serve Dundas and St. Patrick Stations on Line 1.

Queen Station (#13) in 2018 had a ridership numbers of 48,700, while Dundas Station (#9) had 73,560. Having two branches would be able to even out the crowds accessing the Ontario Line. The Queen branch would also draw riders from the south, while the Dundas branch draw riders from the north.

Yes, but now you are having two separate tunnels through downtown, one under Queen and another under Dundas. And yet you only can send an equivalent of one subway line through both of them, because they share the upstream section.

If two separate tunnels though downtown are built, then it is preferable to extend both of them further north / northeast / northwest as separate lines, resulting in double total capacity.

The key is to build them cheaper as you move out. Building branches doubles the cost. Building cheaper (at-grade in a ROW, elevated, or cut-and-cover - in that order of preference) means you can serve more areas.
 
A piece of the Exhibition will be dedicated to testing out new transit technologies.

Exhibition Place could be future transportation testing ground

The idea is to create a real-world testing environment that could be used by researchers and industry, whose findings could help improve Toronto’s transportation network.

It sounds like they are thinking in terms of opening it up to autonomous vehicles, and that does make a lot of sense. That said, shades of the maglev much?
 
So long as it doesn’t end up being inspiration for other countries to introduce new tech in their cities where none of it gets implemented here.

If that ends up being the case at least Toronto can charge the rights for them to use it or something.
