Welcome to Bishop Tonnos Catholic Secondary School.
In 2002, the Hamilton-Wentworth Catholic District School Board approved the construction of a new secondary school in Ancaster to alleviate overcrowding at St. Thomas More Catholic Secondary School on the West Mountain and St. Mary Catholic Secondary School in West Hamilton. The school – the first new Catholic secondary school to be opened in 25 years – was named in honour of The Most Reverend Anthony F. Tonnos, eighth Bishop of Hamilton. Bishop Tonnos served as the faithful shepherd of the Hamilton Diocese from 1984-2010, and was a steadfast supporter of Catholic Education.
An official ground breaking ceremony was held on May 22, 2003 on the grounds of the former 17.5-acre Marshall Potato Farm on Highway 53 just west of Fiddler’s Green Road. In September 2004, the school’s inaugural Grade 9 & 10 students began their first semester of the 2004-2005 school year at the former Christ the King Catholic Elementary School. Bishop Tonnos Catholic Secondary School opened in February 2005 with an initial enrolment of 475 students. An official blessing and dedication ceremony, celebrated by Bishop Tonnos, was held on April 17, 2005. The 178,000 sq. ft. school was built at a cost of $24-million with a Ministry rated capacity of 1,250 students. On June 20, 2016, the Board of Trustees approved the installation of a 110,000 sq. ft. artificial turf sports field at the school. A field blessing and dedication, officiated by Bishop Tonnos, was held on October 6, 2017.
We are blessed to have a modern facility where we can provide an excellent broad-based, balanced education to help young people grow to their fullest potential, where they can see and experience the richness of a Christ centred education, and achieve the academic requirements for the Ontario Graduation Diploma. With the guidance and help of an extremely dedicated staff our young people’s experience will be a journey of faith, academics, social teachings, athletics, relationships, and preparation for life experiences.
It is our goal to serve our community with our pastors, with the parents of our students and with our Bishop, to be part of the Church’s mission to place Christ and the teachings of our Church at the centre of our students’ education, and of their lives, because we truly believe in the inscription in the foyer of our building:
