I visited the top of the C.D. Howe building during Doors Open, and you can visit the original post here. I had a couple of extra shots stashed away. The garden up here is pleasant to visit, and the views of both Ottawa and Gatineau are splendid. The cranes and scaffolding are part of the ongoing work on Parliament Hill. I'll have to come back here again next year for the weekend, now that I know about it.
