Between 1888 and 1906, the number of Catholics in Saint Boniface had increased from 2,154 to 4,615, almost all of them of French heritage. By 1900, Saint Boniface was the fifth-largest city in the West and needed a larger cathedral. Local contractors Senecal and Smith were engaged to build a new cathedral to plans by Montreal architect Jean-Omer Marchand. On August 15, 1906, Monsignor Louis-Philippe Adélard Langevin dedicated the cathedral, which became one of the most imposing churches in Western Canada.
