UNDERDOWN, PETER JOHN. On Tuesday, September 22, 2020, Peter Underdown, 89, passed away peacefully surrounded by his family at his home after a short but courageous battle with pancreatic cancer. He was a loved and admired father, grandfather and friend known for his patience, sharp wit and never ending knowledge of just about anything. Born in London, England on January 12, 1931, he achieved the distinction of Flight Lieutenant in the Royal Air Force at the young age of 19. Years after surviving a remarkable flight accident and fall from 2000 ft, he retired from the RAF at age 38. Peter had met his future bride while stationed in Germany and emigrated with his young family to Toronto in 1969, where he would enjoy a 25 year career as a systems analyst at Sony Music. He was an avid reader, crossword puzzle enthusiast and skilled bridge player who for decades enjoyed weekly card games with a close knit group of friends. He is survived by his loving wife Joan of over 60 years and their children, Richard (Louise), Robert (Janet) and Debbie (Leon) and grandchildren Lindsay, Chantal, Ryan, Lauren, Danielle and Adam. He is also survived by brothers and sisters-in-law Bob and Carol Howes and Trevor and Sylvia Doyle and many nieces and nephews. Peter was predeceased by his sister Pam in Australia in 1998. A special thank you to Dr. Mike Borachuk and the CE LHIN Palliative Care Team, as well as the many caring staff and friends at both his Chartwell Pickering City Centre residence and his local West Hill and Durham Region communities. In lieu of flowers, donations may be made to https://www.debracanada.org/ Due to restrictions surrounding COVID-19, a small family service will take place on Saturday, September 26 at The Simple Alternative Funeral Centre on Brock Rd. in Pickering.
