Miss Dominion of Canada was a beauty pageant held in Niagara Falls for many years, primarily at the Sheraton Brock Hotel, on July 1, Canada's Dominion Day (now known as "Canada Day"), beginning in 1959.
The winner of this pageant represented Canada at four of the world's largest international beauty pageants, Miss Universe (until 1977), Miss World (1962–1979), Miss International, and Queen of the Pacific. The Miss Dominion of Canada pageant originated when the Bruno family of Ancaster, Ontario obtained franchise rights to select and send Canada's exclusive representatives to these international pageants. As many as 40 contestants selected via local pageants across many provinces of Canada competed in the annual Niagara Falls competition. Throughout the 1970s, there were generally between twelve and twenty contestants competing at the final judging.
Most contestants progressed through as many as five consecutive preliminary local and regional pageants, somewhat similar to a golfer winning progressively more competitive golf tournaments, victorious in each one until finally winning the highest level competition. The Miss Dominion pageant required the finalists to participate in events including evening dress, swimsuit, interviews, talent, and various singing and dancing vignettes. Notable individuals selected as pageant judges would then select the runners up and the winner.
The contestant selected as Miss Dominion of Canada would visit nearly every Canadian province and other countries such as the United States, Japan, Australia, and Europe during her one-year reign. Until 1977, Miss Dominion of Canada was the country's representative at Miss Universe. The Miss Universe franchise in Canada was taken over by the nationally televised Miss Canada contest in 1978. Miss Dominion of Canada also represented the country at Miss World from 1962 to 1979 after which the franchise was taken over by Miss World Canada.
