One big issue that I see (or at least perceive) in Ottawa is that it's a city that doesn't belong to itself. I always felt like a "tenant", rather than a full fledge resident. Authorities have worked too hard to make this a (fuckxxx) "city for all Canadians", which has some merits, but falls short of pleasing and catering to locals. This has contributed to a strange self-deprecating phenomenon or lack of civic pride. I'm old enough to remember when the city was trying to get a new NHL franchise and reading in the Citizen's sports comment section "why go see a hockey game in Ottawa when you can "just" go to Montreal".

... So bizarre and wet noodle-y.
The feds - and by extension the NCC - have performed an abundance of urban design faux pas. Granted, there have been a few winners over time (the NAC, the Rideau canal, the parliamentary district overall and Sussex drive come to mind), but the bad far outweighs the good:
• The Greber plan is a disaster and encourages suburban exodus and a massive urban sprawl
• The feds never gave a rat's ass when expropriating downtown Hull communities and building those horrible towers
• They bulldozed Lebreton (which today would be a thriving inner city community with thousands of households, multiple restaurants and shops) to make way for government buildings that never materialized and ended being a brown field which is the laughingstock of people all over the country
• Tunney's Pasture is an eyesore and a complete joke in terms of user experience
• That parcel of land that now houses the US embassy should have been developed in a small entertainment district, with restaurants and bars, or a museum... Not that disastrous bunker.
• The NCC imposed that silly height limit downtown, which resulted in dozens of fat, stubby buildings with zero street interaction to save on space.
• And my all-time favorite NCC blunder: Union Station. This stunning design should be a train station, not another lifeless government building. Imagine the vibe in that area if it were allowed to live it true purpose... I'm heartbroken.
• There are other less well known cases, but it gives me a headache thinking about them
• I also console myself when I hear my Korean friends say "Canada is a boring heaven, but Korea is an interesting hell)... we're not the only ones with a mediocre urban landscape, but I digress.
Having said that, there are some encouraging signs on the horizon such as Zibi, the various building being proposed at Lebreton, a dozen+ cranes downtown, better designs being proposed, a loosening of those silly height limits, the growth of downtown eastward and westward, and that big city feel that is becoming more apparent with each passing year. I think that Ottawa is about to begin its golden age... I hope I'm right.
