Rayside-Balfour was a town in Ontario, Canada, which existed from 1973 to 2000. It is now part of the city of Greater Sudbury. The town was created as part of the Regional Municipality of Sudbury and took its name from the townships of Rayside and Balfour, which fell within the boundaries of the new town; prior to the town’s creation in 1973, Rayside and Balfour were separately incorporated as township municipalities. Although the Regional Municipality of Sudbury was a very important centre of Franco-Ontarian population and culture, Rayside-Balfour was the only town in the regional municipality which had a majority francophone population. It remains as such still today.
