The Holman Opera Troupe, which toured throughout Canada in the 1860s–1880s, were at separate periods, lessees of the London Opera House, the Royal Lyceum, Toronto, the Grand Opera House, Ottawa, and the Theatre Royal, Montreal. The troupe consisted of Mr. George Holman, his wife, his daughter Sallie Holman (soprano/principal singer) another daughter, and two sons, with some others, including William H. Crane and Sallie's husband Mr. J. T. Dalton. Bertha May Crawford (1886–1934), a coloratura soprano from Toronto, was probably the only Canadian singer of her era to achieve significant success performing in major opera houses in Russia and Poland during the First World War and through the 1920s.
