Ottawa benefits from not having a lot of heavy industry and has a government civil service, that while not well paid, isn’t really very poor. It also doesn’t have the racial strife on the same scale as other cities i.e., in the U.S. In a lot of cities I’ve spent time in, there’s a lot of areas of the city where you don’t even think of going to. It's both dangerous and rather decrepit (slum). Older parts of the city and the buildings are just decaying. I see buildings that are falling apart and should be leveled, but that doesn’t happen for whatever reasons. I guess I’m thinking of the so called "rust belt" in northeast U.S. for some of the things I’ve mentioned here.
I also think that having a city plan for many decades that includes parks, green space and the mere fact that there’s been a plan is more a net positive than a negative. Outside of the northeast U.S., you have some really sprawling cities like Dallas/Fort Worth (DFW metro complex) that are newer cities, but are sprawling. To get from the west side of Fort Worth to say the north east side of Dallas (e.g., Richardson), pack a lunch because it will take a hour & a half to get there. And they have plenty of impressive freeways all over the place there. That is problematic for workers (even my ex wife as an example). Don’t think they had any urban plan there at least none that I heard of in the years I spent there. You also don’t have a brown smog hanging over a large city that you do in a few west coast U.S. cities. Some of the things I’ve mentioned in this paragraph are not atypical of other cities west of the Mississippi I’d think.
Anyhow, that is just my point of view, but perhaps it's built on a wider perspective. That wider perspective may contrast or be attributable to having lived in more cities than one all of my life. To drudge up a well known cliche, the grass is always greener on the side of the fence, except of course when you’ve spent time on the other side of the pasture/fence.
I think the problem many city planners and plans that were crafted let’s say in or around the 1950s (if they even had a metro/regional plan) is they underestimated population growth and city sprawl. I agree that train & street cars were often too quickly replaced by buses, but in part, a factor in those decisions is the lack of anticipation of the population growth. Ironically, many cities had street cars which were removed and replaced by buses. But, in the last couple of decades, many cities (at least in the U.S.) have implemented street car systems. When they build rali systems, they often find that there is urban development that grows & is developed very near to those rail systems. From a more historical perspective, most of the growth of Long Island happened in conjunction of the building of commuter rail, now called Long Island Railroad (LIRR).
When you build a rail system, the planning has to be based on 50 years out, not 1, 5 or even 10 years after the system is built. To use an extreme example, you are not going to fix New York city's transportation & commute problems by building more roads. I used to commute from Philadelphia to New Jersey & New York, and even within the Philly metro area by rail a lot & never used a car. Parking is like $50/day, so that was one reason right there, plus you never saved any time driving your car. Some employers even use monthly passes as an employee benefit. I know that New York/Philadelphia is a different situation, but I wonder what the population of Ottawa metro area will be in 50 or 60 years from now?
