A new report from the Region of Waterloo shows that Bombardier is set to miss another ION train delivery deadline.
Earlier this year, Bombardier said they were committed to delivering all 14 trains to Waterloo Region by the end of June.
The monthly update from Bombardier shows only six trains have been delivered with two more expected by early July.
The original deadline for Bombardier was December 2016, that was pushed back several times, most recently spring 2018 and then June 2018.
The region has said it plans to have ION service up and running in December 2018.
The latest delivery delays puts that date in jeopardy because each train needs approximately five months of testing before it is fit for service.
The region has indicated they only need 12 fully tested trains to begin service.
The report says the trains still in Kingston are close to completion and five out of the six trains in Waterloo Region are nearly done testing.
