It's reasonably aggressive and in 5 years will have 3/4 of the city covered as far as main lines for buses to connect to. The big extension to the NW will be complex due to the CN main yard and Yellowhead.
It should have a couple station expansion south to Ellerslie Road and the future hospital site u/c in few years as well... then not too far from YEG in a decade or two.
