Dianne COOPER-BARNES

Dianne Lynn Cooper-Barnes passed away peacefully at University Hospital in London on May 12, 2026, at the age of 61, with her loving husband by her side. Born in 1965, in Dr. McMillian's residence in Tweed, Ontario, she was the only daughter of the late Thomas and Margaret Mastervick. Dianne was the beloved wife of Stu Barnes and a devoted mother to Patricia Cooper-Barkley, Tyler, and Sarah Cooper (Matthew Kneller). She was also a 'second mother' to Sarah, Ashley, and Morgan Barnes (Josh Whittier). As a proud Nana, she will be deeply missed by her grandchildren, Tristan, Faith, Isabella, and her beloved hound dog Wiley Girl. Dianne was a woman of incredible strength and intellect, having worked in nursing, real estate, and as a paralegal, approaching everything with kindness, compassion, incredible drive, and her wicked sense of humor. She leaves behind a legacy of love strongly felt by her family and dearest friends. Arrangements have been entrusted to Cremation London & Middlesex. A Celebration of her Life will be announced at a later date. Online condolences may be shared at www.cremationlondon.com.
