Mary Flannery-Castonguay Obituary
We are sad to announce that on March 26, 2025, at the age of 69, Mary Flannery-Castonguay (Ottawa, Ontario) passed away. Leave a sympathy message to the family on the memorial page of Mary Flannery-Castonguay to pay them a last tribute.
She was loved and cherished by many people including: her parents, Donna Cloutier (Gerald Flannery) and Mary; her husband Marc Castonguay; her children, Alexa, Erika and Christopher; and her grandsons, Brysen, Hudson Castonguay and Krugmann.
In lieu of flowers, the family kindly requests that donations be made in her memory to the CHEO Foundation that reflects her love for children.
