In April 1831, Catholic residents gathered to plan the construction of a church. By May 1832, Bishop Macdonnell was granted four acres of land. The construction commenced and concluded in 1834. On November 9, 1835, Bishop Alexander Macdonell of Kingston consecrated the timber-framed church, adorned with Gothic windows. Pews were installed in 1844, and the original clapboard exterior was stuccoed in 1923.
By 1965, the church had expanded, incorporating a nonagon structure that matched the original windows and featured three sets of oak doors. The sanctuary was also renovated according to the Second Vatican Council's liturgical reforms.
On July 25, 1965, The Most Reverend Thomas J. McCarthy, Bishop of St. Catharines, dedicated the refurbished original church and the new polygonal extension at the front.
St. Vincent de Paul Church stands today as a testament to early Canadian church architecture and is the oldest Catholic Church in continuous use for worship in Ontario.
