Another set back for the revitalization of Toronto’s Union Station.

The city is now projecting the completion will be delayed by up to a year and cost another $23-million.

The project was supposed by be finished by 2015 at a cost of $640-million.  It was already two years behind schedule and $160-million over budget before this latest set back.

A draft report, obtained by the Toronto Star, points to additional project requirements for Metolinx’s track and platform reconfiguration to accommodate the Regional Express Rail Expansion and increases to Go Transit service.

The report suggests the work will take till the end of this year and push the overall cost to almost $835-million.
