I am originally from the GTA and also use a Rebel XT hehehe... I really like how you decided to put them side by said. The long exposure effects are also very neat.
If you don't mind I guess I have a suggestion. I know you probably didn't leave your camera on it's tripod without moving it for a few hours... but I think you picture would benefit if you had tilted and cropped both day and night pictures to look more alike. They both seem pretty slanted.
