The at-grade Eglinton East section of the Crosstown is something Toronto will regret for a very long time. The only reason LRT was suggested was due to Miller and his "great city building" propaganda like somehow the Golden Mile was a Yorkville in the making. It should be grade separated {elevated} across the entire route.
This line will only be able to have frequencies of every 4 minutes each way max as opposed to a grade separated line that could run every 90 seconds and be cheaper to run due to automation. When considering the huge cost of this project, LRT was the slowest, most unreliable, lowest capacity, lowest frequency, and most expensive system to run they could have thought of.
Anything is that TC {and very much Eglinton} was based on Miller's population estimate of Toronto reaching 4 million by 2030 but it set to cross that marker with 1 to 2 years and will probably be closer to 3.5 million by 2030. That's an extra 500,000 people not being taken into consideration in this project. The Canada Line with it's McStations will still have higher capacity than the Crosstown but be much faster, more reliable, safer, and less intrusive than this mega project.
