The Eglinton Crosstown may have the same issues with accidents in the intersections as the Calgarys LRTS do.  This will cause them to shut down transit in the east and west ends where they will travel on their own lanes on  one of the busiest streets in Toronto.  It could have been  underground at each major intersection instead of only underground for the middle 9 km.  I don't care what type of vehicle goes on rapid transit as long as they have sufficient capacity and can travel quickly without getting stopped by traffic problems.   

Putting a single stop  on the Scarborough subway is foolish and makes it look really useless.  A stop at Lawrence would provide access to a hospital and cut bus routes on Lawrence to 15 minutes from the east end.  This is the longest bus route in the city and is bogged down every day getting to the Eglinton subway station on Yonge.    The on-street lines with dedicated right-of-ways for transit are still slow in my experience.
