in the context of your post....I don't understand your rhetorical question. If you are suggesting that if ReR to Brampton was extended further than is currently planned.....that Brampton would be a viable place to work while living in Toronto....why would an LRT taking people out of Brampton make a difference to that?
Read my post again. I said AD2W, not RER.
Right now, the Brampton hourly GO trains stop service too early for Toronto downtown dwellers (who live or study in/near Brampton). The extra trains is the expected continuance of hourly trains through Brampton.
There are other destinations along the northern reaches of Hurontario-Main, and quicker reach to Steeles. With Brampton's fast-growing transit ridership and the
definitely increased GO service (TOAreaFan I do not care how you spin/RER/AD2W it, it's still
increased GO train service) that I feel they were an ideal candidate to get LRT service.
(To be fair: Metrolinx's RER initiative includes both electric and diesels, and the AD2W is a subset of the broad-ranging RER umbrella if RER is a multilayered service term like the Paris/France definition rather than a type of train).
As a commuter (Toronto-Waterloo, Ottawa-Montreal, and now Hamilton-Toronto), Brampton isn't an attractive place to me for work if I were living in downtown Toronto. IT software developers often sometimes suddenly work late unexpectedly, and need predictable easy evening options that they do not dread. Hourly trains that run till nearly midnight (like LSE/LSW) helps fill that void. If Brampton wants to attract incoming commuters, they have done a good job increasing ridership with Züm, attracting all-day GO service, but is now missing the LRT fill-in between Steeles and the GO station. If my theoretical office tower was on the LRT route slightly south of Brampton, the existence of LRT would have increased the likelihood.
As a software developer, I once turned down a six-figure contract because there was no good transit (I really don't want a 1.5-hour-long driving commute behing a steering wheel -- If I am commuting that long I'd rather be fully productive during transit (work sleep catchup Facebook family email telecommute VPN etc) and it is quite important that destinations become transit-friendly. Although I have now homesteaded down permanently in Hamilton, I know many who make decisions whether or not to accept work based on whether it's transit-accessible.
