Anniversary celebration to re-open doors of Assumption Church

A UWindsor history professor will discuss the role Assumption parish played in the development of the region as part of celebrations this week marking the 250th anniversary of the Roman Catholic parish.

In 1728, Jesuit missionary Armand De La Richardie came from Quebec to establish the Mission of Our Lady of the Assumption among the Hurons of Detroit. It is the oldest continuous Catholic parish in the province of Ontario, and the oldest in Canada west of Montreal.

The current Assumption Church at the corner of Huron Church Road and University Avenue dates from 1842. It closed in 2014 pending restorations, but will open to the public August 13 and 15:

  • On Sunday, August 13, the grounds will host an outdoor Mass at 11 a.m., followed by a free community barbeque. From 12 to 5 p.m. the doors to the church will be open for all.
  • Tuesday, August 15, the church will open from 9 a.m. to 6 p.m. At 6 p.m., University of Windsor assistant professor of history Guillaume Teasdale will deliver his free public lecture, “The Wyandot and French Roots of Assumption Parish, 1728-1867.”
