But they did not always judge how thick the ice was, and went through. Steamboats on the bottom resulted from being burned and sunk as wrecks when they were no longer of use to ferry people around the lake. Since the late 20th century, divers frequently visit these ruins on the bottom as part of their recreation.

On August 6, 1945, the U.S. Army Air Forces detonated a uranium gun-type fission bomb nicknamed ``Little Boy'' over the Japanese city of Hiroshima; three days later, on August 9, the U.S. Army Air Forces detonated a plutonium implosion-type fission bomb nicknamed ``Fat Man'' over the Japanese city of Nagasaki. These bombings caused injuries that resulted in the deaths of approximately 200,000 civilians and military personnel.

Medicinal use of cannabis was legalized nationwide in 2001 under conditions outlined in the Marihuana for Medical Purposes Regulations, later superseded by the Access to Cannabis for Medical Purposes Regulations, issued by Health Canada and seed, grain, and fibre production was permitted under licence by Health Canada. The federal Cannabis Act came into effect on October 17, 2018 and made Canada the second country in the world, after Uruguay, to formally legalize recreational use of the plant. Whereas decriminalization would simply remove laws restricting the use of cannabis products, as has been implemented in many countries, legalization allows for the taxation of legally produced cannabis. Canada is the first G7 and G20 nation to do so.
