DURHAM CATHOLIC DISTRICT SCHOOL BOARD
Approved Boundary Changes for St. Elizabeth Seton Catholic School

We are pleased to inform you that the revised boundaries for the new Seaton #1 Catholic Elementary School and changes to select school boundaries in Ajax and Pickering were approved by the Durham Catholic District School Board of Trustees at the December 15, 2025, Regular Board Meeting. These changes were developed through a comprehensive review process and reflect feedback gathered from families during the consultation period.

We sincerely thank you for your participation and input throughout this process. Your engagement was invaluable in helping us make decisions that best support our students and community.

Please note: No current St. Elizabeth Seton students (as of September 2025) will be affected by the boundary revisions.

Boundaries, Maps and Implementation

There are three approved recommendations as a result of the new Seaton #1 Catholic School construction. These include the adjustment of Seaton #1 Catholic School Boundary (recommendation #1), a boundary adjustment to St. André Bessette Catholic School, St. Catherine of Siena Catholic School, and St. Jude Catholic School (recommendation #2), and a boundary adjustment to Notre Dame and Archbishop Denis O'Connor Catholic Secondary Schools to align with the proposed changes in recommendations #1 and #2 (recommendation #3). 

 St. Elizabeth Seton Catholic School Implementation

• Study Area 1 (referred to as "SA 1" in the map) will move to be within the Seaton #1 Catholic School boundary.
• No current St. Elizabeth Seton students (as of September 2025) will be affected by the boundary revision.
• Any new students will be made aware of the upcoming proposed boundary revisions at the time of registration.
• Any new student moving into the new Seaton #1 Catholic School boundary after December 15, 2025, will be directed to the Catholic school associated with the new boundary.
• The secondary school boundary for Seaton #1 and St. Elizabeth Seton is St. Mary Catholic Secondary School and remains unchanged.
• Transportation will continue to follow the Board's Transportation Policy (PO429).

Looking ahead, we are excited to share that further information and opportunities for engagement regarding the naming of the new school will be provided to families in early 2026. We look forward to continuing this collaborative process.
