Welcome to Holy Cross Parish

Welcome to the official website of Holy Cross Roman Catholic Parish. This website contains information on schedules, operations and activities of Holy Cross.  We are a vibrant community located in Oshawa, Ontario in the Archdiocese of Toronto under the pastoral guidance of Rev. Keith Callaghan. Holy Cross is always welcoming to new members and visitors. We are a small community with a big heart. One would say probably one of the Diocese little secrets.


“Each one of us has been given the opportunity to make a unique contribution in the form of our time, talent, and financial support to build up the parish of Holy Cross in order to be a living presence of Jesus Christ in our community.”
