Of Brampton, Ontario, passed away at Guelph, Ontario on Sunday, May 28, 2023, in her 85th year. Beloved mother of Mark (Lorraine), Peter, and Ryan (Nancy). Proud grand-mother of Fiona, Ella, Nathan, Harrison, James, Hudson, and Annabelle. Predeceased by her loving husband, Robert (Bob) Greenham, and brother Nathan (Bud) Davison. Diane was a dedicated and caring primary educator for over 40 years with the Toronto and Peel Boards of Education teaching Kindergarten and Music. Over the course of her life, Diane balanced her love between the rich Niagara farmland of Port Colborne where she was born and raised, and the rugged beauty of her precious cottage in the Muskoka Lakes. Thank you to the staff and residents of Riverside Glen, Guelph, for helping to make Diane's last few years a lovely experience. Her ashes will be spread at a private family ceremony later this summer. Arrangements entrusted to the WALL-CUSTANCE FUNERAL HOME & CHAPEL (519-822-0051 / www.wallcustance.com). If desired, donations can be made to the Alzheimer Society of Canada.
