Don't get me wrong, I agree. But the first person who brings this up is going to get their faces eaten off by no only scarborough residents, but also the Fords (and as a result, probably Etobicoke), the scarborough councillors, and both the Liberal and Conservative Scarborough MPs. I don't think anyone wants to deal with all that, even though I'm sure everyone thinks it's probably the best for everyone.
As long as MPAC is fair with assessments in Scarborough following the completion of this plan, I guess I could live with the current plans. Property reassessments + property tax increase to pay for their unnecessary subway. Either way, Scarborough needs to pay proportionally more since this extension compounds existing systemic issues and does nothing for the majority of Toronto (I can't see any need to ever travel to Scarborough, personally).
