Our Story: Three Hearts, One Trinity

Welcome to Trinity Presbyterian Church in Oshawa! We are a vibrant and unified community of faith formed by the amalgamation of three long-standing Presbyterian congregations in Oshawa: Knox, St. Luke’s, and St. Paul’s. As of January 1st, 2025, we began our shared journey together as Trinity.

Gathering at our Rossland Road location, Trinity builds upon a rich collective history and a shared commitment to faith, community, and service in the Presbyterian tradition.

Our worship is centered on knowing, loving, and serving God, rooted in the truth and inspiration of the Holy Scriptures. We are a down-to-earth community that extends a warm welcome to everyone—whether you are exploring faith for the first time or looking for a new church home.

Our Mission & Outreach

At Trinity, our faith calls us to action. We maintain a strong focus on missions and outreach, striving to make a positive impact in the Durham region and around the world. We believe in nurturing faith across all ages through Bible Studies, Youth Groups, and community fellowship.

Our Ministers

We are currently served by the Reverend Bill Grace and the Reverend Deon Slabbert.

As Trinity Presbyterian Church, we look forward to honoring the legacies of our founding congregations while prayerfully stepping into the future together, guided by God’s grace.
