Algonquin and Lakeshore Catholic District School Board (ALCDSB), in collaboration with Loyalist College, celebrate the first ever graduating class of the School-Within-A-College (SWAC) pathway program.

At the end of each month, the CEO will share an update with all families that celebrates the people, learning and achievements within our schools, while also providing important board-wide news and information.

More than 130 golfers helped raise $25,714.33 to support ALCDSB students and families in need of urgent financial assistance.
