The present cathedral was designed by architects Maurice Perrault and Albert Mesnard. The total cost of the building was C$81,052 Based on the plans for a church built in Vaudreuil-Dorion, Quebec, Perrault and Mesnard borrowed much from the medieval architecture of European churches. The double asymmetrical towers are typical of Quebec churches and a characteristic of the High Victorian Gothic style. This was an attempt to follow the "unfinished" look that made fourteenth and fifteenth century churches popular. The main tower boasts a spire that was designed to hold a clock and a set of bells.
