Honestly I find the anti-Mississauga bias to be quite bizarre. Mississauga is highly connected to Toronto. Hurontario & Burnhamthorpe is 24.3 km from Yonge & Bloor according to Google Maps (using Avoid Highways option). No one can tell me 24.3 km is too far for a subway to go. SCC is 19.3 km from Yonge & Bloor according to Google Maps (again using Avoid Highways option). That makes for a 45 km (Dundas-)Bloor-Danforth subway, not 100 km as DENTROBATE54 has claimed. Big difference there. As for the so-called big gap between the 427 and Hurontario--just, huh? Eastern Mississauga is probably the densest part of the GTA outside the 416. Just, WTF? And Dundas? Can you say ripe for redevelopment? As for GO trains hourly on the Milton line, we need that TOO. Not one or the other. Some people need to get to Union. Some need to get to Dixie. Some need to get to Islington. Some need to get to Dundas West. Some need St. George. or whatever.
Here we go again. Just because some people say that Mississauga isn't the best place for a traditional subway line and alternatives should be looked at doesn't mean we're all biased against Mississauga. Some of us who argue this are from Mississauga, some spent much time there (for example, although I didn't live in Mississauga, both of my parents were employed there).
You just need to wrap your head around an idea... regional rail. Something that exists in New York and every damn city over 250,000 in Europe. Basically, we're saying WE WANT MISSISSAUGA TO HAVE A SUBWAY, and we want it to have the following characteristics:
- We don't want it to take over an hour to get people downtown.
- The way Mississauga has grown and will grow, we need transit to go further than MCC.
- We want it to serve the thousands upon thousands of people and jobs in Erindale, Erin Mills, Meadowvale, and beyond. And we want to make it easier for people in Erindale, Erin Mills, and Meadowvale to reach MCC.
- We don't want it to overload the already crowded Bloor line (the second busiest line from downtown after the Yonge line).
This does not mean a GO train every hour. It means a subway-train-like train running every 20 minutes or better. Adding two new tracks to the Milton Line for dedicated transit usage, with a re-route through MCC would allow for higher-capacity, faster, more attractive, more affordable transit operation than simply extending Bloor-Danforth line. It could be just like a Bloor-Danforth extension, only running express from Kipling onwards.
It's not a simple hierarchy of subway>GO train>streetcar>bus... it's about choosing what can provide the best transit service for the purpose. And regional rail is the best mode for regional trips. Mississauga, Brampton, Durham, Oakville, Burlington, they all need frequent higher-order transit. Subway cannot serve all these needs. There's no existing regional rail equivalent for Yonge (don't say Richmond Hill GO, which runs through a valley parkland for almost its entire route). And for that matter you won't see me defending the VCC extension, I think Woodbridgeites would be far more likely to ride an upgraded Barrie or Bolton GO line.
I'll finish off with a comparison of Toronto to Berlin. Berlin's subway moves 457 million people per year, while their regional rail system moves 375 million, 18% less. Toronto's subway moves 1.2 million people per weekday, while GO trains (which are commuter rail, NOT regional rail) move 170,000, or 86% less.
There's a lot of room for growth in GTA-wide rail service.
