In addition to lodgings, the hotel offers a number of event spaces. The hotel features an entire floor of function rooms, primarily used for conferences. A notable room at the hotel includes the Ballroom, which features an oil-painted ceiling from the hotel's opening. The Concert Hall is another event space at the hotel that is outfitted with a Casavant Frères pipe organ. With five manuals and one-hundred-and-seven stops, it was the largest pipe organ in Canada. Another notable event space within the hotel is the Imperial Room, which was once used as a nightclub from the 1940s to the 1990s. The space featured a stage at the north-end of the room, a sunken floor with tables and a dance floor in the middle, and raised booths at the other end of the room. The room is presently used as a meeting and event space, most often by the Empire Club of Canada.
