But the BCA was TTC / City Council centric and didn't consider GTA transit planning as a whole. Did the BCA consider the impacts of a Durham BRT offloading at Scarborough Centre? Did it consider the Metrolinx McCowan BRT link between Markham Centre and Scarborough Center? Did it consider where to best locate transit hubs in the city (i.e. Urban Growth Centres) and how this plan fits into that vision? I suspect that the BCA only looked at the SRT as a single route in isolation of others, put no relevance on hub locations, and looked at growth trends largely based on the current and planned transit system which is cumbersome to use.
It seems quite obvious to me that most BCA and EA studies run by the city seek out to validate an already made decision, not to find the best solution. If Metrolinx is given some teeth and controls the purse strings things could get fixed, otherwise a trip from York U to U of T Scarborough will end up a transfer at Finch West, a transfer at Finch, a transfer at Sheppard, a transfer at Don Mills, and a transfer at Scarborough Centre rather than a transfer at Downsview and a transfer at Scarborough Centre.
A good transit system would have one hub in each Urban Growth Centre identified in the Places to Grow document and direct transfer-free routes between neighboring Growth Centres. Scarborough Centre is one of the Growth Centres and its nearest neighbours are Yonge & Eglinton, North York, Markham Centre, and Pickering Centre. Transit City is at odds with the provincial vision so the question becomes... is the province going to do anything about it or will it allow Toronto to spend money on miscellaneous routes which do not come together to form a cohesive system supportive of Metrolinx and Places to Grow goals.
