The transfer volumes at Eglinton-Yonge Station will be pretty low. Highest transfer volume is westbound Eglinton Line to southbound Yonge Line, at 1160 passengers in the peak hour. That's the capacity of one Toronto Rocket trainset. The southbound Yonge Line platform is already pretty crowded in the AM, but I don't imagine another 1,160 passengers over 60 minutes will dramatically change the situation. Population and employment growth in the Yonge-Eglinton area will probably play a much bigger role in exacerbating the crowding problems at Eglinton Station.
The introduction of the Relief Line North should pretty much obliterate the westbound to southbound transfer volume at Eglinton Station. It'll probably be in the 500 passengers per peak hour range when the DRL North opens. ATO will also bring significant crowding relief to Eglinton Station when its enabled.
