Elgin Mills? A potential extension of the extension should really only go to Major Mackenzie in terms of development potential along the corridor. I guess a further extension to Elgin Mills does make sense if you consider that Viva Blue runs in mixed traffic between Major Mackenzie and just south of Elgin Mills, however that really shouldn't be an high priority.In this thread before it was suggested that it could eventually be extended to Elgin Mills, significantly reducing the length of the Yonge Viva route.
If you were addressing my post above, then just to be clear I was referring to the Yonge corridor between Hwy-7 and Elgin Mills.Bear in mind that ignoring the capacity issues to the south, the Hwy 7 extension makes a LOT of sense from a network perspective - as hubs go Richmond Hill Centre is damn good, with the Subway, 407, RH GO, hwy 7 and Viva meeting in a fairly TOD friendly location. Going further north reintroduces exactly the kind of linear transfers that people hate, and adds a transfer between Viva on Yonge and Viva on Hwy 7.
It could be a light rail line up Yonge, starting at Hwy 7 and going north. Tunnels could be built in sections where street widening is impossible (Aurora?).I'd prefer a solid BRT route over an elongated subway line whose reliability is dependent on no delays occurring on the rest of the line.
It could, eventually... But the Morraine pretty well stops intensive development on a big chunk, and a sensible service patterns demands whatever goes north of 7 continue to Newmarket. A Richmond Hill tunnel will be justified long before converting to rail, and I fully expect Hwy 7 light rail to make sense before Yonge does assuming we have RER on the Barrie line.It could be a light rail line up Yonge, starting at Hwy 7 and going north.
