Ottawa is more of a region.
Ottawa in terms of land, is bigger than the city of Toronto, Montreal, Vancouver, Edmonton, and Calgary put together.
I always use this as my example of why a city with such a low population density is limited in how effective public transportation can be. It's either too costly to have buses going to every nook and cranny every 10 minutes...and having one bus come by every 30 minutes to serve thousands of people isn't efficient.
You either get affordable and inefficient or efficient and bankrupting the city.
That's why Ottawa, being so spread out, should worry about road infrastructure, at least on the outer end, more so than hyper focusing on public transit. I'm hijacking the thread, but express buses coming to Orleans and dropping you off downtown was WAY quicker and more efficient than trying to take a local bus to place dorleans to then take a bus to Blair to then get on a rail. Wtf were politicians thinking? Ottawa doesn't have the population density or the money in their coffers to make this project work.
