The Chapel is the center and heart of St. Mary’s High School. The Chapel was dedicated in 2004 by (then) Bishop Anthony Tonnos of the Diocese of Hamilton. The Chapel serves the needs of all staff and students. Students and staff may visit the chapel to pray, reflect and spend quiet time in the presence of Our Lord. Classes and groups may use the chapel for liturgies, reconciliation, Eucharist and religious events.


“Don’t let anyone look down on you because you are young, but set an example for the believers in speech, in life, in love, in faith and in purity.”
– 1 Timothy 4:12

Hello St. Mary’s!

My name is Deacon Ed MacIntosh (you can call me Deacon or Deacon Ed) and I am extremely blessed to be the Chaplain for St. Mary’s High School. For 10 years I was the Chaplain at St. David in Waterloo and for the 10 years before that I worked in the Elementary School panel doing retreats at Mt. Mary, Camp Brebeuf, and Paradise Lake (YMCA).

I am very excited to be here at St. Mary’s and continuing this journey with you.

Please feel free to stop by my office for a chat or just to say “hello!”
