Welcome to the Holy Trinity Catholic School website! 

Holy Trinity Catholic School is a kindergarten to grade 8 school located in southeast Sarnia.  Our school serves a diverse population and I am pleased to say that approximately 440 students and 45 staff members are proud to call Holy Trinity their home school.   With the support of St. Benedict Church right next to our school, we are a dynamic Catholic Community dedicated to providing an outstanding faith-based education.

At Holy Trinity Catholic School, we are committed to working with the parents and our greater community to provide the best learning environment for all of the students in our care.  Our staff members are dynamic and extremely dedicated as they strive to meet the needs of our students so that they can reach their potential.  Children learn by example so it is our responsibility to be outstanding role models in our daily lives. 

Over the past year, we have been making wonderful strides to within the school and community to incorporate 21st century learning skills and now is the time to make this progress visible.  This website (along with our twitter handle) will aim to keep students, parents and the greater community better informed of the wonderful things happening at Holy Trinity Catholic School.

We look forward to continuing our work within the community and hope that you enjoy browsing our updated website!

Privacy Advisory

Our families and staff enjoy opportunities to share some of their activities with parents and the school community through teams, clubs and special events. Many of these are ‘memory making’ for families and as such, photographs and videos are often taken.

We ask that families exercise their discretion when taking photographs or videos at school events and consider the privacy of other students who may also be present in those pictures. We would appreciate if families not upload images of students other than their own to the Internet (e.g. YouTube or Facebook). Your cooperation with this request is appreciated.
