Posting this in the suburban skyline thread, but it's mostly just suburb, without the skyline.
The lower part of the image is Ottawa, just outside the traditional downtown. From left to right, we have the National Research Council HQ (stone building on the river) and the Lester B. Pearson Building, HQ to Global Affairs. Next we have Green Island, with the former City Hall (original 1958 building and 1988 Moshe Sfdie addition). The Feds now own it, a second office for Global Affairs, named John G. Diefenbaker Building by the Harper Government (oh, the irony).
On the other side, next to the river and falls, is Tavern on the Falls followed by the French Embassy. The rest is the Rockliffe Park and New Edinburgh area. The more forest like setting to the far right is where you'll find the Prime Minister's residence 24 Sussex (river side, though not lived in since Trudeau was voted in, for renovations that still haven't happened) and Rideau Hall, home to the Governor General.
On the other side of the river is the Gatineau sector of Gatineau.
