400 Barrels Of Toxic Waste - In February 2017, a man in Ontario discovered 400 barrels of toxic waste hidden behind the walls on his property. He had originally only discovered 400, but found an extra 400 barrels after knocking down the wall (making a total of 800 found barrels). John Currie, the building's past owner, was known for inappropriate waste disposal when he operated a tar product business there.
