In April 1831, the Catholic residents met to discuss building a church. In May 1832, four acres of land were deeded to Bishop Macdonnel. The building process began and was completed in 1834. Bishop Alexander Macdonell of Kingston blessed the frame church with its Gothic windows on November 9, 1835. Pews were added in 1844. The original clapboard siding was covered with stucco in 1923.
The original building was enlarged by 1965 with the addition of a nine-sided structure compatible with the original windows and including three sets of oak doors. The sanctuary was updated in keeping with the liturgical directives of the Second Vatican Council.
The Most Reverend Thomas J. McCarthy, Bishop of St. Catharines, blessed the restoration of the original church and the polygon-shaped addition to the front of the building on July 25, 1965.
Today St. Vincent de Paul, an example of early church architecture in Canada, remains the oldest surviving Catholic Church still used for regular worship in the Province of Ontario.
