No really sure where you are trying to go with this post? But ill take the time to shed some light as it seems what is obvious to me and for whatever reasons is not quite clear
1..
"Scarborough council" -
After amalgamation with Toronto, community councils were formed to process issues considered local to their community.[61] Scarborough's community council, made up of Scarborough's ten councillors, meets once a month at the former offices of the city of Scarborough just south of the Scarborough Town Centre. ...
My point and fact was the Scarborough councillors were heavily pushing for the BDL extension to Miller. There are better references which speak of Scarborough councillors requesting the subway in Millers term Ill have to dig them up if you still really have any doubt?
Here's a good one to dispel the notion that subways was a new Ford phenomena : http://www.pressreader.com/canada/toronto-star/20051027/282093452134773 Ironic to see David Soknaki of all councillors asking residents to sign a petition for the subway during Millers years. There is certainly far larger subway roots here than what is told to the average outside resident. Like I said all Leaders from all stripes and basically all Scarborough politicians at all levels knew what to do when Ford ran with it at the front of his campaign. Not really discussed but Fords opponents in Giambrone and Smitherman both ran directly on the subway extension to SCC.
Heres a bit about the review in Millers term that spun into his Transit City
https://transit.toronto.on.ca/subway/5115.shtml "The question of extending the RT did come back into play starting in 2005, as the TTC calculated that the Scarborough RT was ten years away from requiring significant renovations in order to keep operating. With the Mark I equipment nearly obsolete and not available for production from transit vehicle maker Bombardier, the TTC considered what would be needed to keep trains operating beyond 2015. An extension of the Bloor-Danforth subway was expensive, and upgrading the line to handle Mark II ICTS vehicles was also costly. When the TTC compared these options to converting the line to conventional LRT operation....
2. Ive always supported/defended the SSE (moreso on the RT corridor) as a line. But as a network ive supported any plan that connects the Centre to the existing infrastructure and in conjunction with a better detailed overall plan on all other routes. The sheppard subway would have been proceeding had council agreed to Ford-McGuinty SCC connection to the Eglinton Crosstown as Sheppard subway was the other half of that agreement. Not sure I understand what you mean with the "system will be enough" We are currently designing BRT, LRT local feeders, local/core with the subway and GO RER spread out over many areas serving many differing needs. A very detailed overall plan for the entire City is now moving forward and the funds are being directed in the right place, while I personally don't agree with all the details/alignments it still meets various needs and most importantly its a plan that will be supported by the residents who are directly impacted the most and we can finally move forward.
