Allan Terwilleger was a loving father, dedicated husband and selfless firefighter with 30 years service to the people of Oshawa.

It is with profound sadness that we announce the passing of Allan on April 26, 2025, at the age of 82. He died peacefully in his sleep in the supportive care unit at Lakeridge Health Oshawa after a long battle with cancer.

Allan was the dearly beloved husband of Helen (nee Higgins) and devoted father of Jill and Paul (both deceased). Helen, Jill and Paul meant more to him than anything else in this world.

Predeceased by his parents Margaret and Archie, and siblings Eileen, Peg, Donna, Gloria, Fran, Archie, Ralph, Don and Judd. He is survived by his sisters Kaye and Jean.

He will be deeply missed by his sister-in-law Ann Higgins and her spouse Graham Rockingham, his nephews Alex, Matthew and Michael, the Way family and the Higgins family (of Peterborough) as well as many dear friends who were so much a part of his life throughout the years.

Allan served with dedication on the Oshawa Fire Department for 30 years, retiring as a Captain in 1995. During retirement he and his wife Helen enjoyed many trips overseas including a Pilgrimage to Spain where he served mass at one of the local churches.

A fan of the Leafs, Blue Jays and Argos, Allan enjoyed skiing, golfing and biking. He was active in his community, delivering Meals on Wheels for 15 years as well as offering his time to several other charitable activities in the area.

A lifelong resident of Oshawa, Allan loved to learn of its history and was always interested in listening to the stories of those he met. He was a truly gentle soul, as well as a devout Catholic, serving as an alter boy daily, and at the first midnight mass at St. Gertrude’s church.
