No. Last election had a very high turnover of councillors (most retired, few incumbents defeated). I expect council after the election to look pretty similar to what we have now. Obviously, if Ford wins Stintz will not be on council.
That said, a provincial election between now and October could certainly shake things up; though I suspect the choices are LRT in 2020 or subway in 2040. Hudak will quickly cancel the LRT but if he's funding from the existing taxes the DRL will be forced to be funded first and will take 5 to 10 years to do it; the banks and Board of Trade will insist on it.
He would be short even if Finch, Sheppard LRT, and chunks of Eglinton were cancelled. I expect Yonge would take priority over Sheppard too from a provincial political view. Ford's relationship to Hudak was pretty weak even when Ford was at his peak popularity.
