If they're being "transferred to Eglinton," that just means even more people will be on Yonge before the Bloor/Danforth crowd gets a chance to get on Yonge trains. Sheppard could also flood the Yonge line with tens of thousands more riders, not to mention the Yonge extension, Don Mills, Morningside, etc., all of which will only add riders that use Yonge & Bloor station. The *only* solution is to have less people using the Yonge line...and it's not like there's any capacity to spare north of Bloor. The Spadina extension will address this by removing Finch West riders away from Yonge. South Etobicoke passengers already have an intervening transfer opportunity in the form of the University line.
