The guy was working away with a screwdriver and an adjustable wrench, and the camera was moving all over the place for a good hour. I thought he might be re-positioning the camera, but it ended up at its original position again.
If you don't have a condo overlooking the site, nor work in an office with a similar view, I discovered the sbux at Indigo Books (Eaton Centre) has an amazing view of this building under construction!
