I received a copy that newspaper ad in the mail along with a brief covering letter, so I assume Metrolinx mailed them to all residents within at least 700 metres of the line.
I emailed the provided contact person inquiring about how this particular double-tracking segment (Steeles to Rutherford) fit in with the other ones, but received no reply.
Can't remember where, when or what about seeing an expansion to doubling track from the double track bridge over CN to Wilson with a new GO Station for Sheppard as well keeping the current University one.
Keeping the University should happen and moving it closer to Steeles. Shepperd was plan for the subway when it open in 2016/17
Under the old EA Act, anything over X distance change the Ontario EA to a Federal EA which has more teeth in it, longer to do and one reason the Blue22 EA was broken up as 3 different EA's. When the new one came into effect, not sure what happen for distance and one reason why you are not getting answers to your email as well mind on the expansion.
In the next year or 2, 1 or 2 EA will surface for the Dupont Grade Separation and a station at St Clair and Eglinton. One can say that the line will be double track from south of Dundas to Rutherford.
One reason for having more than one is to get various sections being built at different time due to funding issues than doing it all at once. Doing it in phases has a larger impact on service since it will take longer to do than all at onces. It may also have to do with manpower by Metrolinx in doing one EA vs. X numbers as well construction.
The Barrie Line will not have the same issues as the Georgetown when it comes to construction.
This line is a drop in the bucket for the big picture and getting the big picture built in 10 years now.
