Marc A. Caissy

1943-2025

Age 81 years

Marc passed away peacefully on Sunday, August 31st from mixed dementia after a 3½ month stay in a long term care home in Bourget, Ontario. Before his time in long term care Marc lived in the Ogilvie Villa retirement home in Ottawa for 15 months.

He was the loving brother of Claire Lebeau, Suzanne Caissy, Joanne Caissy (Louis-Paul Allard),and Madeleine Caissy. Pre-deceased by his birth parents Claire Guité and Paul-Emile Caissy and his adoptive parents Rhéa Giroux and Roland Lebeau.

Marc will be missed by Jeff Porter (life partner), his sisters and their families, his nephew Nicholas Main as well as close friends of many years including Paul Laplante, Mark McCormick, Fr. John Stopa and the McIntyre family.

Marc was born in late December 1943 in Montreal and adopted in 1944. He was raised with Claire Lebeau in Eastview Ontario (now Vanier) by his adoptive parents.

At age 38 Marc wanted to learn about his birth family. Through friends he heard of an experimental program in Québec to help adopted people find their birth family. Marc was accepted into that program which led to him being introduced to his birth family in the Gaspé region.

His teaching career began in 1963 teaching elementary school followed by many years of University studies. Marc then taught high school from 1979 to 2008 and concluded his teaching career at St. Mark’s Catholic High School in Manotick.

Mark found a welcoming community at St. Joseph's Catholic Church in Ottawa and used his experience and education as a homilist, lector and Eucharistic minister.

After his retirement from teaching Mark continued his contribution to St. Joseph’s and also traveled in Canada, the United States, Ireland, Iceland and the Netherlands with his partner Jeff.

Marc’s family thank the kind staff of the Ottawa Hospital, Ogilvie Villa, and Caressant Care in Bourget.

In lieu of flowers please consider a donation to St. Joseph’s Supper Table or a charity of your choice.

Mass at St. Joseph’s Church, 174 Wilbrod Street at 10:30 a.m. September 16th, 2025 preceded by visitation at 10:00
