Diamond Tooth Gertie's Gambling Hall is a casino in Dawson City, Yukon, Canada. It was first opened in 1971 by the Klondike Visitors Association, making it Canada's oldest casino. Gertie's, as it is colloquially known, as well as most of Dawson City is reminiscent of the area's Klondike Gold Rush history. Patrons are treated to a daily vaudeville show inspired by one of Dawson's most famous dance hall stars from the Gold Rush era, Gertie Lovejoy, who had a diamond between her two front teeth.
