A city councillor is asking why construction of the York University subway station appears to be stalled.

Coun. Anthony Perruzza tells CBC News the construction site has been idle for months and water has filled a giant hole where the station will eventually be built.

The TTC says the project has shifted from the contractor who dug the hole to a second contractor that will build the station. That process includes testing, inspections and extensive paperwork.

The TTC tells CBC News heavy machinery will be on site this week. Station construction is expected to be complete in 2016.
