The Rideau Transit Group has missed three deadlines to complete the Confederation Line but said it intends to hand over the LRT system before the end of June.

Dominion, Westboro and Tunney's Pasture stations will be closed to riders from 5 a.m. to 2 p.m. on Mar. 31. and connecting buses will be detoured, according to OC Transpo.

Given doubt that the LRT will be ready by March 31, some councillors questioned whether a freeze on transit fares should be extended beyond July 1 at Wednesday's transit commission meeting.

After two missed deadlines, the city still expects the Confederation line to be completed "sometime" in the first three months of 2019. The consortium building the train was supposed to hand over the keys to the system on Nov. 2.

The city's finance committee heard Monday that the consortium building Ottawa's Confederation LRT line told the city they could not meet all their contractual obligations by their Nov. 2 deadline, despite a six-month extension granted to them earlier this year.

The number of layoffs is about 200-250 less than initially projected.
