One of the tallest buildings in western Canada is the Bow. It was originally going to have a twin tower, but there was a bit of an economic downturn that prevented it. I think that might be better as a solo building; this futuristic-looking skyscraper really stands out and adds a very modern flair to the skyline. Inside it appears to have some really high ceilings and very luxurious-looking office space. Maybe one day I will take a tour and get some pics from the inside.
