In the very last scene two Royal Canadian Mounted Police SUV's can be seen off in the distance revealing this location to be in Canada.
At the end of the episode, when Shaun walks out of the hospital in the rain and looks back, the "San Jose St. Bonaventure hospital" sign on the building's wall is missing. The city hall of Surrey, British Columbia, Canada that is used for exterior shots of the hospital obviously does not have this lettering in real life.
