For the most part, I think people are spot-on about how Ottawa does not have as many services designed for luxury consumption as other cities, even other cities in the same size range. This is a big drawback when you're young and rich.
That said, I wouldn't underestimate the value of living in a city where the average Joe does better. According to
this article, Ottawa has the second-lowest proportion of low-income citizens (behind only boomtown Calgary). And, while there's room for improvement, Ottawa has a pretty good record for treating its least fortunate. This is a pretty important consideration. It's not actually all that desirable to have to live in a gated community or an isolated suburb because the downtown in the metro area is ravaged with crime and poverty (hello, Detroit and St. Louis!). Also, being very wealthy in a highly unequal society is an exercise in cognitive dissonance where you constantly have to rationalize your own wealth in the face of the abject poverty of others.
I'm not sure how much that consideration plays out in reality - I think services for luxury consumption are still probably more important at the end of the day - but it's something I would think about, all else equal.
