For a long time the laws of Canada have explicitly banned gambling in any form. This may be the reason why the country does not have so many gambling establishments as the USA - but their quality surely makes up for the quantity. The first Canadian casino was opened in Dawson City, Yukon, in 1972 - it was the first one after gambling has been banned in the country in 1892. The Diamond Tooth Gertie's Gambling Casino did not operate for long, though. The first permanent commercial casino was opened in 1989, and it was the first of many - there are currently 75 casinos operating on Canadian soil.
