Generally speaking training facilities in Ottawa could be better. That being said a person has to work with what he has. On the Quebec side (Gatineau/Hull) it's pretty much the same.
It is my understanding that the Ottawa Athletic Club is a good place to train, with competent trainers on staff. Might be worth a google.
The main YMCA here is dated. However, it has (more or less) all the equipment a person could use.
Outside of this, it's the usual fare of training facilities: community, and the universities- which are completely accessible to the public.
The outdoors is where it's at for running, cycling. That will be self evident when you visit.
It's a small town.
