BLACK HISTORY MONTH: The Durham Catholic District School Board recognizes and embraces Canada's diverse culture. During the month of February, St. Mary joins with other schools and organizations across the nation to celebrate the contributions and history of Canadians whose roots are in Africa, the Caribbean and South America. Black History Month gives our schools a wonderful opportunity to celebrate the achievements of members of Black community. As a faith community, Durham Catholic District School Board embraces and promotes human dignity, inclusivity, respect, diversity and justice. Please visit DCDSB Equity and Inclusive Education for more information. Please visit the Black History Committee page to see how St. Mary will celebrate.  

LENT: On Ash Wednesday February 22nd we begin the liturgical season of Lent as a time of preparation leading up to the celebration of Easter. By observing the 40 days of Lent, Christians honour Jesus Christ's sacrifice and withdrawal into the desert for 40 days. Traditionally, Lent is marked by fasting, both from food and festivities, prayer and almsgiving. In recognizing that this season of Lent, looks and feels very different we can strive to find meaningful ways to grow in our relationship with God and journey with Jesus on the road to Calvary. Please see DCDSB Lenten Calendar to participate in our daily activities and prayer. 

COURSE SELECTION: Course Selection is an important component of Secondary and Post-Secondary Pathways Planning. Please visit Guidance: Course Levels and Calendars for more information about courses offered in 2022-2023. Course selection forms and fees are due (date to be determined)
