The 1970s and 1980s saw a number of major hotel projects in central Toronto, with the Sheraton Centre, Toronto Hilton, Sutton Place, and Four Seasons adding thousands of new rooms to the market. The economic downturn at the end of the 1980s saw several hotels run into financial trouble. Since the mid-2000s, a booming real estate market, especially in downtown Toronto, has led to a number of new hotel projects, often in combination with condominium projects. An unprecedented number of major hotel projects were completed in central Toronto, including The St. Regis Toronto (formerly known as Trump International Hotel and Tower then The Adelaide Hotel Toronto), the Ritz-Carlton, Living Shangri-La, and a new Four Seasons Hotel and Residences Toronto.
