Toronto council wants a proposed TTC “relief line” — which could run south from Donlands or Pape station to downtown and connect to the other side of the Bloor subway — made a priority over extending the Yonge line into York Region.

Council voted yesterday to ask Metrolinx to make the relief line — an idea that’s been kicking around since the late 1980s — part of its 15-year plan instead of its 25-year plan, and push it ahead of the Yonge extension.

The cost of the Metrolinx-backed 6.8-kilometre Yonge project is estimated at $2.4 billion. The TTC will soon submit its own report on the plan to the Ontario environment ministry, along with conditions for approval that could double the cost.
