Loving Mother to Manfred and his wife Nancy, Yvonne Riggers, and Terry and his wife Sandra Riggers. Beloved Oma to Nathan Riggers and his partner Jen, Kira Riggers, Kendall Riggers and her partner Cory, and the light of her life, her only great-grandchild, Falon Riggers Glazier. Ilona is pre-deceased by her loving husband Gerd Riggers, parents Paul and Anna Sladeczek, and many siblings. She is survived by her brother Paul and his wife Wendy Sladeczek and extended family. Ilona will be dearly missed by her many friends, especially her best friend Inge and her husband John Huber, and her special friend Ivan Jeric. Ilona was a long-standing, active member of Club Loreley in Oshawa, where she enjoyed socializing with her friends and dancing the night away. She loved flowers and was an avid gardener. Ilona loved to travel and enjoyed life to the fullest. She loved her family and friends dearly. And she made the best soup in the world. Cremation has taken place. A small private family gathering was held on Thanksgiving. A very special thanks to her best friend, Inge Huber who loving assisted the family in caring for Ilona during her illness. A Celebration of Life will be held at a later date. In Lieu of flowers, donations can be made to the Durham Regional Cancer Centre, Humane Society of Durham Region, or the charity of your choice.
