It is with profound sadness that the family of David Brian Marzetti announces his sudden passing at Markham-Stouffville Hospital, on Wednesday November 25th, 2020, at the age of 65. Dave will be forever remembered by his wife Hilary of 43 years. He will be deeply missed by his children, Adrian & Larissa, his grand-pup Bailey, and his brother, Richard (Silvia). He was predeceased by his parents, Elio & Assunta Marzetti, and his sister, Pamela. Dave will also be fondly remembered by his extended family, co-workers and friends. Born and raised in Sault Ste. Marie, ON to Elio & Assunta Marzetti, Dave developed a passion for electronics and cars, and loved exploring the mechanics of both. He studied Computer Science at the University of Waterloo, where he met his wife Hilary, and a few years later, teamed up with five other like-minded individuals to build Filbitron Systems Group until his retirement in 2015. David’s passions included, rallying, HAM radio, and snowmobiling, becoming an active member in each of these clubs and organizations. He loved to share his passions with others; helping out anywhere and anyone he could, usually by building something on the fly to solve a problem. The family would also like to give a special thanks to his doctors, nurses and caregivers at Markham-Stouffville Hospital for their exceptional and compassionate care. In lieu of flowers, the family would prefer donations to be made to the Markham-Stouffville Hospital Foundation mshf.on.ca. A private graveside service will take place and a celebration of life to occur at a later date. Memorial condolences may be made at www.forrestandtaylor.com.
