I also like that shot of the white post/buoy and especially the reflections and the negative space. It's very simple and for that reason, very effective.
Having spent some time in Toronto a very long time ago, was that skyline shot from Ontario Place? Which was, as I recall it, like an island where they had some sort of exposition at one time? Anyway, I like that shot and how it brings back my memories of that truly great city.
