Gerard (Gerry) P. J. Mainguy
GERARD PAUL JOSEPH MAINGUY, affectionately known as “Gerry,” passed away peacefully surrounded by family at Hospice Wellington in Guelph, ON, on September 2nd, 2025, in his 90th year. Born September 14th, 1935, in Sturgeon Falls, Ontario to Alphonse and Imelda Allaire Mainguy. Gerry was preceded in death by his loving wife, Jeannine Paquet. He was a devoted father to children Deborah Pedersen (Bent), Mark Mainguy (Pamela), Kyle Mainguy (Sabrina) and stepchildren, Larry Paquet, Sonya Cullen (Tim), and Ronnie Paquet; and beloved Pépère to Melissa (Jon), Rachel (Wesley), Kyra (Japeth), Ashley (James), Dane (Abigail), Joshua, Amanda, Kristina, Nikki, Jeff, Victoria, and Kayla. He was the proud Great Grand-Pépère to 16 children.
Gerry gave 41 years to General Motors Oshawa and even in his retirement was known for his hard work. A man of few words, he let his actions speak for him. Whether you needed to borrow a tool from his workshop, bodywork done on your car, help with a home reno or a carpentry job, he was the “Main Guy” friends and family would turn to. Gerry would give the shirt off his back –even if it was his Blue Jays Jersey.
He was a cherished brother to Lucille DesOrmeaux (Arthur), Sr. Irene Mainguy, Aurore Monette (Alpheda), Fernand Mainguy (Claire), Rollande Olmstead (Laurent), Jeannette Plante (Orald), George Mainguy, and Jacques (Denise), Gerry enriched the lives of many through his kindness and dedication.
