Dr. Clive Lewis Greenstock


August 14, 1939 – July 12, 2020

It is with great sadness that we announce Clive’s passing after a long struggle with many health issues following five devastating hemorrhagic strokes.
He will be forever loved, remembered and missed by his wife of 55 years, Gwen, his daughters and sons-in-law, Erica and Glenn Charette and Andrea and Tom Patrick and his granddaughters Keely and Kiana Patrick. He will also be missed by Gwen’s sisters and brothers- in-law, Claire and Peter Shragge and Marilyn and Harold Duplacey and their families, as well as relatives in the US and South Wales. He was predeceased by his parents Clarice and George Greenstock.

An only child, Clive was born and raised in England on the outskirts of London where his father was a police officer. He excelled in school and obtained a BSc in Physics at Leeds University and an MSc in Medical Physics at the University of London. He came to Canada to do a PhD in Medical Biophysics at the University of Toronto in 1964. He met and married Gwen in 1965 and they had an amazing life together, living in many places and traveling all over the world. Clive was a research scientist at Atomic Energy of Canada Ltd. (AECL), first for 18 years in Pinawa, Manitoba and then for 17 years in Chalk River, Ontario. He and Gwen lived in England on two occasions – in London for two years right after his PhD on a post-doctoral fellowship and a year’s sabbatical in Manchester when Andrea and Erica were in Grades 4 and 6. That year was a fantastic experience for the whole family. Clive retired in 2005 and enjoyed good health and nine great years of retirement before his first stroke in 2014. He and Gwen traveled widely with their Fifth Avenue Collection business, as well as for pleasure and spent their summers at their cottage on Round Lake, surrounded by family and friends. Even after his first stroke, life for Clive was pretty good and he and Gwen were able to live a somewhat normal life, including trips to China, India, Europe and the Panama Canal, until 2018 when four more strokes changed his life forever. These past two years have been very difficult, but Clive bore it all with tremendous strength and courage, tried as hard as he could to recover, and was loved by everyone who knew and cared for him.

In addition to his work, Clive absolutely adored his daughters and granddaughters and liked nothing more than playing with them for hours on end, building play structures, forts, snowmen, teaching them all kinds of sports and life skills and helping them understand the world of science around them. In addition to his family, his next love was a toss-up between sports of all kinds and cars of all kinds – and the sportier, the better. He loved to travel the world, for his scientific work and for the pleasure of exploring cultures unlike his own.

The family wish to thank Dr. Bruce Strader, Jean Benton NP, Christine Rossi RN and the nursing staff of 2C at Marianhill for their excellent care of Clive and especially for such love and compassion shown to both Clive and Gwen in his final days. We are also indebted to Mark Peever PT, and his staff from House Calls Physiotherapy, and Dr. Debbie Timpson and her staff at the Rehabilitation Unit of the Pembroke Regional Hospital for their kind and compassionate care of Clive over the years. We are very grateful to all of our friends and relatives, who visited Clive in hospital and at Marianhill and lent their support to all of us, especially during these past two years.
In remembrance of Clive, please consider a donation to the Pembroke Regional Hospital Foundation or a charity of your choice.
As per Clive’s wishes, cremation has taken place. Due to the constraints of covid-19, a private family grave side service will take place. Arrangements by the
