Here is the issue
The area around Islington is densely populated with families. Those are homes, buildings and a majority of them are occupied by families with children. Many of whom work and commute downtown.
That is a tiny snapshot between two major intersections. It goes like that for miles. Is it as desnly populated as some areas getting the LRT? No. However it still houses around 200,000 people.
All that needs to be done is have one LRT line down Islington to Eglington, or, more preferably, going to the subway station.
That one line would serve over a hundred thousand people, easily. Islington is one of the main bloodlines of Etobicoke, especially since it connects to the 401 at Rexdale BlVD.
I am not saying get rid of any specific LRT line. I am saying add one for Islington. The money that will be made will recoup the cost of putting it in.
Another incentive is many of the people building the LRT will be from this area. It's very working class, and a substantial number of the residents are in or connected to the construction business. If you every want to see one section of the LRT system built quickly, on budget and efficiently, it will be the Islington line.
