The Sheraton Centre Toronto Hotel is the 33rd-tallest building in Toronto, Ontario, Canada, and is the tallest all-hotel building in Toronto. When it opened in 1972 it was the second largest hotel in Toronto with 1,450 rooms, behind only the Royal York Hotel. The hotel was originally a joint venture with the Four Seasons chain, and was named the Four Seasons Sheraton Hotel. That connection was severed in 1976 when Four Seasons founder Issy Sharp sold his 49 percent share in the hotel.
