Saint Joseph's Church, Scarborough
The first Saint Joseph's Catholic Church was one of many small rural churches established in Ontario during the 1850's to serve the needs of the growing Irish Catholic population which had left Ireland following the great potato famine of 1847. It was the first Roman Catholic Church to be built in Scarborough and the fourth in Metropolitan Toronto.
The first Masses were said in local homes from around 1850. In 1854 Rev. Jean Baptiste Proulx, Pastor of Oshawa, began to erect on this site the first church. St. Joseph's, Highland Creek, was a mission church of St. Gregory's, Oshawa, from 1854 until 1860; of St. Francis de Sales, Pickering, 1860-1914; of Saint Augustine's Seminary, Scarborough, 1914-1929; and became an independent parish in 1929.
