Nothing, Ottawa is one of the most beautiful cities in Canada, it is home to the world's longest, outside, skating rink, the Rideau Canal. Thee major rivers meet at mid city. There are many great eating places, a great museum of technology, a world class war museum, and it home to the hockey team, The Ottawa Senators.

I agree with the above... Ottawa is a great place to live.

The public transit is annoying, especially if you live in the suburbs. The highway commute can get bad also, but not nearly as bad as Toronto.

Also, if you don't speak much or any French, you may be limited in what jobs are available to you. Although Ottawa is mostly English-speaking, we're right on the Quebec border and many jobs (especially in the government) prefer or require bilingualism. Of course, that depends greatly on what line of work you're in.

Besides that, there's a decent nightlife, plenty of restaurants, shopping and movie theaters. We have the Sens, if you're a hockey fan. And being close to cottage country and provincial parks is nice for a bit of fresh air.
