It could cost at least $2.1 billion to end work on Calgary's first phase of its long-sought $6.2-billion Green Line light rail transit project. City officials and Green Line board members say more than $1.

The cost of winding down the transit project will amount to a minimum of $850 million, on top of roughly $1.3 billion already spent.

Calgary city council is set to face the fallout Tuesday of losing Alberta government funding for its Green Line light rail transit project, as Mayor Jyoti Gondek says it's clear the province isn't willing to budge on its rerouting demands.
