I think that a Kanata North transit connection to the O-Train can be handled by extending the Baseline BRT buses through Bells Corners, along Moodie, Carling, and March to Kanata North. This route also connects the DND campus to the Moodie Station. The actual BRT lanes would not need to be continued along the entire route, but the rail overpass on Carling should, probably, be replaced.
The blue line in this image would be the BRT bus route:
For fun, I have included a path for an autonomous electric vehicle, following the green line. I have put it along the Golf course corridor, since that will be new development, and is fairly central. This would give Kanata North the chance to prove that it is a leaded in small, autonomous transit vehicles. (Because of the potential for snow-covered roads, I would suggest using a buried-wire guidance.)
