St. Mary Catholic School (Trenton) Home

The Algonquin and Lakeshore Catholic District School Board (ALCDSB) is excited to launch our new Board themes, which will guide us in our faith journey over the next five years.

Congratulations to the eight Algonquin and Lakeshore Catholic District School Board (ALCDSB) students who placed at the Quinte Regional Science and Technology Fair (QRSTF).

Wishing all families, staff, and community members an enjoyable summer break!
