Jean-Étienne (Stephen) Fournier (c. 1852 - 1929) was a Canadian politician, who served as the first mayor of Sudbury, Ontario.
Fournier was born about 1852 in Trois-Pistoles, Fournier worked for the Central Canada Railway and the Canadian Pacific Railway in Petawawa before moving to Sudbury, where he became the community's first postmaster[1] [2] [3] in 1884. In 1885, he established the community's first general store, and was elected reeve of McKim Township. When Sudbury was incorporated as a town in 1893, he became the town's first mayor,[3] and served a second term as mayor in 1896.[3]
Fournier was also chair of the town's first school board; classes were initially held in his own home until the town's first school was built. Fournier Gardens on Louis Street in Sudbury was named in his honour.
