I'm really not seeing the Collingwood thing.
While thousands of carloads converge on the area both summer and winter, one has to consider where those people come from and how much a commuter train would really help them make the trip more conveniently. My take is - not much and not many. All those cars fan out across various highways - no doubt a lot at the 407, more at 401, not to mention 89, 9, and 124. The catchment area for both Wasaga and the ski business extends from Oshawa to Kitchener - and beyond.
Carrying all those folks downtown to Union and then asking them to take further transit to get home is not going to sell. This is a market where the auto is truly more convenient, even with the congestion created.
I could certainly see a demonstration bus service from Allandale GO, meeting GO trains and demonstrating whether there is demand to either ski hills, Collingwood town, or Wasaga Beach. Certainly some business would appear, and that would be useful to calibrate whether a GO extension is justified.
Relaying the 15 miles of track from Utopia to Stayner, and refurbishing the line east of Utopia to achieve reasonable passenger train speed, strikes me as much lower priority than laying down 15 miles of track on many other places in the GO network. That same envelope would likely make a much bigger difference on Stratford - London, for instance.
I can buy extending GO to the west side of the 400, as proposed, as a way of keeping cars out of central Barrie - but no further.
