Definitely unlikely. Not a surprise to me, as there isn't demand for LRT service levelss.
The only way to effectively serve airport, north/south travel in Etobicoke , and trips with suburban origin and destination points is BRT. LRT is too expensive to effectively cover a substantial portion of suburban trips.
100 km of BRT could be built for about $1 Billion, delivering 25% to 30% shorter travel times, and more reliable service to 1/4 of TTC trips. It's perhaps the cheapest, quickest and most impactful improvement we can make to transit in Toronto.
The greatest deficiency in our network is how poorly it serves suburban trips, which make up most TTC trips. This is reflected in the extremely low transit modal share for tips with suburban origin and destinations. I hope somebody at City Planning is willing to examine the idea. It's the only way to improve these trips.
