OLG Casino Sault Ste. Marie  Gateway Casinos Sault Ste. Marie (formerly OLG Casino Sault Ste. Marie) is a casino in Sault Ste. Marie, Ontario. Owned an Operated by Burnaby based Gateway Casinos & Entertainment, it was Northern Ontario's first full-time casino when it opened in 1999. The casino is located near the International Bridge which links the city to Sault Ste. Marie, Michigan. Food and beverage facilities offered by the casino include a 100-seat restaurant and a bar. The gaming area is in size and includes 450 slot machines and 21 game tables. There currently are no accommodations or entertainment facilities on site, making it difficult for the facility to compete with the other casinos in its local market located minutes away in the State of Michigan. The current casino facility has been housed in a temporary movable dome structure since opening in 1999 and has required numerous repairs due to its long-term use. Although the City of Sault Ste. Marie is currently home to the Ontario Lottery and Gaming Corporation, much like its past financial decision to operate two offices, the corporate office based in Toronto currently has no long-term plans for a permanent presence in the Northern Ontario city in the form of any significant investment into any permanent structures. The casino derives some of its customers from the United States, in part because the drinking age in Ontario is 19, as opposed to 21 in Michigan.
