Saskatoon's Projected Growth Map has been updated as of March 23, 2017. See map
here.
The map indicates a BRT Transit Corridor (Red Line): Blairmore/University Heights/Holmwood. The map also indicates a High Frequency Corridor (Blue Line): Lawson/Nutana.
Not sure why the Blue Line doesn't extend into Stonebridge. Budget constraints, perhaps?
At any rate, there are 19 BRT Stations running east-west on the Red Line, as well as another 5 BRT Stations extending into Saskatoon's northeast on the Red Line.
