The Windsor Hotel was soon at the centre of Montreal's social and business worlds, attracting not only railway visitors, but also business leaders, politicians, socialites, artists, and even royalty. The hotel was home to both the annual St. Andrew's Society Ball and the Winter Carnival Ball, the former being a mainstay of the hotel and of Montreal's social calendar for nearly a century. Sarah Bernhardt, Mark Twain, Dolores Costello, Rudyard Kipling, Fanny Davenport, Lillie Langtry and Oscar Wilde were among the Windsor's famous guests in its early years.
