WINDSOR, Ont. — The local banking community and countless families are mourning the sudden loss of Marc Bissonnette, a retired Scotiabank manager and pillar of the community, who died unexpectedly this week just two days after celebrating his 67th birthday.
Bissonnette passed away after a brief illness, leaving behind a legacy defined by four decades of trusted financial service and a deep, abiding devotion to his family.
For 40 years, Bissonnette was a familiar and reassuring face in Windsor’s financial sector, building a career renowned more for personal connection than for profit. He retired from Scotiabank several years ago but remained a well-known figure, remembered by former clients for his integrity and his “unforgettable million-dollar smile.”
“He wasn’t just a banker; he was a confidant,” said longtime client Eleanor Shaw. “When my husband passed, Marc helped me sort through everything with such patience and kindness. He made you feel like family, not an account number. This is a terrible loss for Windsor.”
Beyond the bank, Bissonnette’s world revolved around his own family. He was the beloved husband of Diana, his partner of nearly 50 years, a proud father to Lauren and Matthew, and an adoring “Papa” to his three grandchildren, Cohen, Ella, and Emersyn.
“His grandchildren were his absolute pride and joy,” said his daughter, Lauren Thibert. “He had a whole list of projects and trips planned with them for his retirement. He lived for family dinners, coaching from the sidelines, and being their biggest cheerleader. We are shattered.”
News of his passing has sparked an outpouring of tributes on social media, with many sharing stories of Bissonnette’s quiet generosity—from guiding young couples through their first mortgage to offering compassionate advice to seniors navigating their finances.
His professional philosophy was simple, according to a former colleague: “Marc always said, ‘We’re not just handling money; we’re helping people build their lives.’ He embodied that every single day.”
A private family service will be held. The family has suggested that in lieu of flowers, those wishing to honor Marc Bissonnette’s memory consider an act of kindness in his name—a gesture that reflects the man who built a life and career on warmth, steadfast support, and a legendary smile.
