The Parliament building is nice, you go with a tour guide who had a great knowledge of the building and Canada's history - and can see the backstage of the Canadian quiet politely politic debate. And it's priceless if there are Americans together in the same tour and hear they asking: "wait, the tour is almost ending and you haven't said anything about Canada's president, where's his room? And who's he?"

They could improve the ticket center though, you have to wait in a long line on the streets.
