Skoob is right that the streetcars are terrible at best. The city deliberatey hamstrung the system and that's let to terrible service even in dedicated lanes.
- There's no signal priority over cars at intersections so streetcars stop twice at every intersection.
- There are too many stops especially along Queen. The worst is near the Eaton Centre, where the streetcar stops at University, York, Bay, in front of the Eaton Centre, Yonge and then Victoria. They should remove the cross walk in front of the Eaton Centre. For one, there's a pedestrian bridge right above the crosswalk and Bay and Yonge are very close together. They could remove many other stops to increase the service speed
- Streetcars still crawl through most intersections because the driver has to watch for the switch position. The driver has to exit the vehicle if the position is in the wrong position. There are automatic switches, but the TTC hasn't changed many of them because they cost more.
- We should stop closing the streetcar lines along King for TIFF or Queen for other events. There has to be a way to run those events while keeping the streetcars running.
I don't think these issue exist on St Clair because there are no streetcars lines that cross 90 degress to it. The same is likely true with Eglinton and Finch. On the other hand, I think they also do not have signal priority over cars.
They have to resolve these issues to increase efficiency and reliabiltiy to the system. The Queen route should improve once the subway is running. On the other hand, I don't know what will happen on the surface.
If LRT is "1920's technology" then why are these cities and more investing in them? With Bombardier vehicles no doubt. You're obviously unaware, but many Chinese cities are investing heavily in LRT

Funny you mention Hong Kong because it built a light rail system in the mid-80's in one of the newer communities and I've ridden it many times.
https://en.wikipedia.org/wiki/Light_Rail_(MTR). The government set aside land for the tracks while the neighborhoods were going up. The vehicles do look dated, but they work quite well. The system moved almost 500K people in 2015.
