You could say that it's too far along, too late to make changes. They are already doing design meetings with the bidders for the major contract that includes the surface part this year, although that contract doesn't become finalized till Spring 2015.
Anyways it's a huge "if", this is very very hypothetical. Clearly Ford didn't get his way during his first term as mayor. If he did, Eglinton would not be under construction, and the Sheppard east subway extension would be going ahead..
He also implied he would get rid of streetcars during his 1st term and they are still running.
So there are multiple hypotheticals that need to happen to even get to this scenario.
