Bertrand Leo Dube, 80, of Nashua, passed away unexpectedly at his home on November 1, 2025. Born in Quebec, Canada on March 11, 1945, he was the son of the late Lionel and Lucia (Mailloux) Dube.

Bertrand was the devoted husband of Lise (Allaire) Dube, with whom he shared 59 wonderful years of marriage.

He worked for 35 years at Ingersoll Rand and later retired from Costco, where he was employed as a maintenance worker. Known for his strong work ethic and kind heart, Bertrand was respected and well-liked by all who knew him.

Outside of work, Bertrand found joy in life's simple pleasures. He loved fishing, hunting, and playing cards—especially cribbage. He also cherished dancing with his beloved wife during their years together in Canada. Bertrand will be remembered for his warm smile, sense of humor, and the deep love he had for his family and friends.

In addition to his wife Lise, Bertrand is survived by his daughter Julie Dube; his daughter-in-law Dannielle Dube; his five grandchildren Scott Dube, Angelia Dube, Brian Dube, Christopher Dube and Jason Dube; his nine great grandchildren; his sister Sylvia Labonte and her husband Martin; as well as several nieces and nephews.

Bertrand was predeceased by his two sons, Mario and Donald.

Family and friends are invited to Bertrand's funeral mass on November 14th, 2025 at 10:00 am St. Louis de Gonzague Church, 48 W. Hollis Street, Nashua. Interment will follow at St. Louis Cemetery.
