Prayer Of Peace in recognition of recent violence in Quebec


Prince of Peace, today we pray for peace in our hearts, in our minds and in our actions.  In a world struggling to find meaning and often finds itself witnessing deliberate acts of violence, help us be peacemakers.  Grant us the wisdom, insight and prudence to resolve issues and conflicts without violence.  Grant us the vision to recognize that we are all unique and different.  Help us to see the commonality rooted in our humanity, dignity and worth.  Help us to embrace the model that you lived and to love one another as you continue to love us.



(based on a prayer from 365 prayers for Catholic schools and parish youth groups, Novalis, 2016)

 The Online Reporting Tool

The Dufferin-Peel Catholic District School board has developed a new way to help nurture a safe, caring and inclusive school environment.  The Online Reporting Tool is intended for students in grades 3 – 8 who become aware of bullying incidents and negative behaviours.  The student can simply ‘click’ on the link below to fill out the report.  The report will then be directly emailed to the principal and/or vice principal and will be dealt with accordingly.

It is important to recognize that the Online Reporting Tool is an alternate reporting option.  It is best practice to speak directly with a responsible adult at home and/or in the school.

St. Sebastian Catholic Elementary
School Motto

“Soldiers of Faith, Endurance and Freedom”

St. Sebastian Catholic Elementary School

St. Sebastian Catholic Elementary School, located at 3460 Aquinas Avenue in northwestern Mississauga, opened in September 2004 and was blessed on May 3, 2005.  The focus of our school community is the successful working relationship of school, home and parish triad. The school actively joins our parish, Merciful Redeemer, as evidenced by our close relationship with the parish team. Our pastors and other lay church leaders connect to the school through Masses, St. Vincent de Paul initiatives, Sacramental Preparation and Youth Ministry. 

Our school is named after the martyred Roman Praetorian Soldier who was killed for converting people to Christianity. He is patron saint of athletes because of his physical endurance and his energetic way of spreading and defending the faith.  We believe our school motto, “Soldiers of Faith, Endurance, and Freedom”, encapsulates the essence of the life and example of St. Sebastian and the individuals who are members of our school community. Our academic achievement, faith and social action initiatives continue in the valiant spirit of St. Sebastian as our school community demonstrates its devotion to Gospel values. Our charity food drives and fundraisers, Virtues liturgies, Masses, sacraments and liturgical celebrations following the church’s liturgical calendar and, perhaps most importantly, our daily interactions with one another foster the development of our academic, spiritual, personal skills and achievements to become Soldiers of Christ.
