I love how everything is so straight and square. When I shoot wide, everything warps! Are you doing any straightening in post processing? LOVELY photo, by the way! In fact, I like this even better than your ribbon winner (which is a fine photo as well.) This one has more depth, more fine detail in it.
I'm thinking that HDR was used to obtain the results you have here, especially in the detailed shadows. Regardless...you did a very nice job with post tools to put together a fine image here. Well done!
Lots of shots on here of the CN tower are taken from across the water. Nice to have a different perspective, and you have it perfectly positioned between the two buildings.
