The Shady Sanitarium is a Canadian mental hospital in "The Harum-Scarum Sanitarium", an episode of The Scooby-Doo Show. It is near Niagara Falls in Ontario.
Dr. Tooksbury is the owner of the sanitarium. He operates it with his two guard dogs, Cuddles and Schnookums. The previous owner, Dr. Coffin, is deceased.
The sanitarium was losing potential patients because it was the center of a gold-smuggling operation, elaborately covered up by Officer Oldfield posing as the ghost of Dr. Coffin.
