Yup, substantial parts of Ottawa's Transitway over the next decade or so will be upgraded to LRT. It was partially designed for LRT in that it has grade separations in key places, but for stations outside of the downtown (Blair, Cyrville, St. Laurent, Train, Hurdman, Lees, uOttawa, Bayview, LeBreton) they're being more or less completely rebuilt in order to support LRT, although the degree of reconstruction varies depending on the station.
And many of the stations downtown are being completely replaced by the tunnel anyway.
Ottawa's Transitway serves as a baseline route for the replacement LRT, but it's largely no different from fresh construction from scratch.
