Join us for a contemporary Christian experience in the beauty of an historic cathedral



Our Parish has a simple mission: To know Christ, and to give glory to God. We welcome all people to our community of worship, service, and evangelization.

Whether you’ve been a Christian your entire life, or you’re interested to learn about Christianity and the Catholic faith, our welcoming, faith-centric community is a place to discover and experience.




The centre of our Parish is the iconic Cathedral of Saint Peter‑in‑Chains, an historic Roman Catholic church located in the heart of Peterborough, Ontario.

This remarkable church, which has stood for over 180 years, is emblematic of our Christian heritage, a bridge between yesterday and today. Come, see what the contemporary Catholic experience is all about, in the beauty of an historic cathedral.




Our Parish is blessed to have an extraordinary team of faith leaders, known in the community for their devotion to Catholic faith and principles.

If you are seeking Christ in your life, have questions about the Catholic faith, or are interested in becoming part of a faith community, speak to one of our priests. They invite your questions, welcome dialogue, and are always willing to help!

New to the Cathedral?

Are you seeking Christ, curious about the Catholic faith, or simply new to the Peterborough area?

As a Catholic faith community, we’re here to spread the gospel of Jesus Christ. We believe there’s no better way to live this life than in the moral principles of the Christian faith.

Attend a mass or other faith event. Talk to a priest. Meet others in our community. Check out the Schedule, our weekly Bulletin, or the Contacts section below. You can also find us on social media!

Become a volunteer

Our parish is a vibrant community of Christians, just like you. Many contribute their time, energy, and talent to ministry through music, hospitality, and many other ways.

Consider becoming a volunteer. Whether you have a musical talent, would enjoy speaking, are gifted in hospitality, have professional knowledge, or simply want to give back by assisting during masses and other events, there’s a place in our Parish where you can help. See the Ministries page to learn more.


The Cathedral was constructed in 1837 and is easily one of the most iconic and recognizable buildings in the City of Peterborough. In addition to the regular operational expenses of a living, breathing faith community, funding the ongoing maintenance of an historic building is a major operational challenge for our Parish.

Help ensure that our children will know and enjoy this beautiful Cathedral in the years and decades to come. Please consider regular donations, or donate online.
