It is with deep sadness that we announce the passing of Dr. Mark Antoniazzi on August 20, 2025, at Joseph Brant Hospital, at the age of 71. Mark was the devoted husband of Linda for 30 years, and the loving father of Mark (the late Anna) and Andre (Lidia). He was a proud Nonno to Ava, Ella, Sofia, and Marco. Mark was the cherished son of Mary and the late Lino Antoniazzi, and the dear brother of Alan (Rachel) and Marcia Antoniazzi. He will also be missed by his brothers- and sisters-in-law Annette (Marc), Diane (Bruce), Julie (Mark), Anita, and Mike (Lisa), as well as his many nieces, nephews, aunts, uncles, cousins, and friends.

Mark lived a life filled with compassion and music. He loved playing guitar and was a long-time supporter of “League of Rock.” A dedicated clinical psychologist, he spent more than 50 years helping others. In his early career, he worked at Downsview Rehab Hospital before moving to the Toronto Rehab Hospital, where he supported brain injury patients. He later established a respected practice, Baxter Antoniazzi and Associates, serving the communities of Hamilton and Burlington.

Visitation will take place at Bay Gardens Funeral Home, 1010 Botanical Drive, Burlington, on Tuesday, August 26, 2025, from 2–4 p.m. and 7–9 p.m. A private family service will follow, with cremation to take place afterward.

In memory of Mark, donations to The DeMazenod Door Outreach or your local food bank would be greatly appreciated. Messages of condolence may be shared online at www.baygardens.ca.
