It is with deep sadness that we announce the passing of Tobias (Tobi) David Mankis, aged 40, who left us unexpectedly on June 13, 2025, after a short and courageous battle with cancer. He was an adored son, brother, uncle, and friend whose gentle and kind spirit touched everyone who knew him.

Tobi had a wonderful appreciation for nature and spent much of his time outdoors. He enjoyed hiking and birdwatching, and his love of photography and videography allowed him to capture the quiet beauty of the wildlife and landscapes. Being a thoughtful and curious reader, Tobi found joy in learning through his immense book collection.

He studied at the Royal Military College, the University of Toronto, and Laurentian University, leading to a dedicated career in Science Communication. The friendships and colleagues he formed during those years remained close to his heart throughout his life.

Originally from Waterford, Ontario, he later built a home and community in Sudbury, Ontario where he was known for his wit, generosity, and his love of the outdoors. His Sudbury circle became like a second family, sharing in his adventures.

Tobias is predeceased by his father, David and he is survived by his mother, Twila; his sister, Larissa (Greg); and his beloved nieces, Evelyn and Amelia, to whom he was a fun-loving uncle.

A celebration of Tobi’s life will be announced at a later date. In lieu of flowers and in honour of Tobi’s love for the environment and science, please consider a donation to Junction Creek Stewardship Committee (https://junctioncreek.com/donate/).
