Ottawa is Canada's majestic capital city. Greater Ottawa has a population of over a million people, the city is across the Ottawa River from Hull, Québec. Your first stop will probably be the historic Parliament Buildings. Here is the seat of the Federal Government. In the summer see the 'Changing of the Guard'. At night you can see a sound and light show, and listen to a symphony performance.
The downtown area is close to Parliament Hill, visit Confederation Square (the site of the National War Memorial and the National Arts Centre). Go down to the Rideau Canal which has 10km of pathways around it. Go canoeing, or in winter, skate on what becomes the world's longest ice rink.
Two places that should not be missed are the National Gallery of Canada and the National Museum of Science and Technology.
