Well, I tried to explain the situation in the SSE thread, without much success. But will try one more time.
There is no point building parking garages in the middle of Etobicoke. Eg West LRT will get a substantial percentage of its riders just walking to the stations. For those who live too far to walk, central Etobicoke has a decent bus network, and every bus route crossing Eglinton will connect to at least one EWLRT station.
The interceptor parking garages need to be built at the edge stations. In case of EWLRT, the natural location is at the Renforth Gateway. If someone is driving from Bolton via 427, or from Milton via 401, they can leave the car at the edge of 416, and take the LRT if it goes where they want to go. For example, to the Yonge & Eglinton area. If there is no parking there, they will drive all the way to their destination. They will not switch to their local bus that runs once in 90 min, or to GO that only runs to Union.
The policy of not having parking spaces at the edge stations is effectively pro-emission (encourages more car-kilometers driven), even though its proponents are kidding themselves into believing they are pursuing the green agenda.
