Passed away peacefully in Toronto on October 13, 2025, after a long and brave battle with Alzheimer’s and prostate cancer.
Peter was a devoted husband, father, brother, brother-in-law, uncle, and grandfather. He leaves behind his beloved wife, Dorothy Joy Lothian; his children, Alex (Tania) and Nina (Scott); and five cherished grandchildren, Ben, Emily, and Aliana Lothian, and Claire and Kieran MacDougall. He will be dearly missed by his sister, Elizabeth Dyment, and fondly remembered by sisters-in-law Catherine MacHattie and Susannah Ames, extended family, and many friends.
Peter’s life was rich with friendships and community, built through skiing, running, hiking, paddling, work, and many other passions. Known for his chatty nature, he often lingered longest at tea time after church or struck up conversations with strangers on family walks—much to the amusement (and occasional exasperation) of his family.
A passionate cook and baker, Peter’s specialties included muffins, Christmas cake and pudding, hot cross buns, marmalade, and his famous “everything cookies.” Born in the United Kingdom, he took a leap across the pond to Montreal in 1972 for a programming job at the Bank of Montreal. He met Dorothy through skiing and paddling shortly after arriving and what was meant to be a 2-year stay turned into a lifetime in Canada. Together they shared decades of active pursuits—cross-country skiing, hiking, biking, camping, sailing and paddling with family and friends.
Peter and Dorothy traveled extensively, with highlights including a trip to the Himalayas to see snow leopards, officiating cross-country skiing events at the 2010 Vancouver Olympics, visiting Nina in Zambia, sailing adventures around England, Lake Ontario, Guyana, Trinidad, and Argentina. They also explored parts of Europe and Egypt, often with Peter’s sister Liz and her friends.
Even in his later years, Peter remained active—often walking home from radiation appointments in downtown Toronto, partly for the exercise and the chance to explore, partly for the story it gave him to share with friends and family.
The family extends heartfelt thanks to the compassionate caregivers at Wesburn Manor for their kindness and support. Special thanks also go to Dr. Christina Reppas and Dr. Rachel Wortzman for their exceptional care and dedication throughout Peter’s health journey.
A celebration of Peter’s life will be held at Humbercrest United Church, date still to be confirmed. In the meantime, please feel free to share a memory or reach out to connect.
In lieu of flowers, donations in his memory may be made to the Bruce Trail Association, the Salvation Army, or Médecins Sans Frontières.
Peter will be deeply missed and lovingly remembered by all who knew him.
