Also, don't forget that Scarborough already has the subway, and has far superior GO service than any part of York Region.
Objection on the "far superior GO service" part. Central and north-eastern Scarborough has no GO trains, only two stops of the infrequent, mixed-traffic GO buses. Western Scarborough has the Stouffville line, with service as lousy as York Region's. Only the southern and eastern parts of Scarborough are close enough to the Lakeshore East GO stations and a relatively frequent service.
Furthermore, York Region has the "50c-to-GO" fare integration arrangement (subsidized by GO, not by YRT), local bus routes optimized to serve GO stations, and ample parking lots for those who prefer to drive to a station.
In contrast, Scarborough residents have to pay full second fare for taking TTC to GO; the local transit network is not integrated with GO (with the exception of Kennedy Stn); and there aren't many parking spaces at GO stations within Scarborough.
