Regenesis is my absolute favourite tv show and it's filmed in Toronto. If you want the science that goes with each episode here's your link:
The show's mission statement is: The North American Biotechnology Advisory Committee is a trilateral taskforce from Canada, Mexico and the United States to investigate research in biotechnology including the related fields of bioweaponry and nanotechnology.
So every episode they are investigating some crisis caused by either faulty science or scientists implementing new processes without having thoroughly studied the effects of those processes on people or the environment. Unfortunately it's extremely frustrating if you don't start at Season 1, Episode 1 and work your way through as each story builds on the one that proceeded it. At the end of Season 2, there was a terrorist explosion in the lab and it takes all of Season 3 to figure out who was killed and what injuries the survivors sustained. You only find out about an injury when the scientist runs into difficulty performing his/her job because of it.
