Dixie, Cawthra, Cooksville, MCC, Streetville, Meadowvale...
These locations are all on (or just off of) major arterials and would not require major transit re-routings. Most of Mississauga's busiest routes serve these stations already. I wouldn't consider any of those stations to be "middle of nowhere". Just like in Toronto, re-routing buses to serve rail stations does not mean disassembling the grid. What it does mean is that someone heading from Meadowvale to MCC would be routed onto a faster, more comfortable train for part of their trip.
Lets see...............Dixie over 5+ minute walk from the 1's let alone the 5's. The 5 has poor service outside peak.
Cawthra has no real bus service. Depending where you put a station that connect to Dundas, it will be a 5 minute walk or more. 1 does has good service with the 81.
Cooksville has good service on 19, but falls off for the 61. It's a 5 minute walk from the 28 to get too the station. Ridership on the 2 shuttles is poor.
Erindale is about a 5 minute walk to either the 9, 38, 6 or 26, but all have poor service.
Streetsville is a 5+ minute walk to either the 9 or 44 that has poor service. You have 49 and 10 using the station a peak time as well adding more time to riders travel time who use the 10.
Meadowvale only see peak service only and is no where land.
Lisgar sees the 38 now 7 days a week. There is new peak service for weekday only.
Getting to Meadowvale to get to MCC is a pain in the rear and not worth the time to use GO in the first place. It takes the #9 35 minutes to get terminal to terminal. Add in the time that takes a rider to get there, they could be looking at an hour travel time. It ends up been a no winner for riders in the Meadowvalle area until the 109 hits the road next month. GO will never cut the mustard to service MCC with good service as it stands now.
Go and talk to the Burlington Route 1 riders as what they think about the off route trip they have to take to get to the Aldershot station considering next to no riders get on/off at the station in the first place. It is about a 10 minute walk from the station to Plains Rd. It's a waste of their time.
I have issues when major riders are ignore for a few ppl who use GO or other transit routes that forces riders off the grid system.
As long riders have to pay more money to use more than system, very few ppl will use a GO-? off grid service.
