Lakeshore Psychiatric Hospital (Etobicoke, Ontario, Canada)

Although the former psychiatric hospital (the “Asylum by the Lake”) has been closed since 1979, and the buildings are now part of the Humber College Institute of Technology and Advanced Learning, there’s still nothing like gothic old asylum buildings to fill a morbid heart with contentedness.  And you can visit the cemetery and remember all the poor, misunderstood souls who suffered there over the years. (Thanks to Lady Morgana for the suggestion.)
