We Remember

MARTINUS, Sebastian William
April 15, 2010 — April 24, 2025
Sebastian Martinus left us far too soon on April 24, 2025, at just 15 years old. His passing, under the heartbreaking circumstances of accidental overdose, has left a space that can’t be filled – but his impact, his laugh, and his love will never fade.
Sebastian was a bright spirit – always fun, curious, and endlessly kind. He had a charismatic presence: goofy and quick-witted, full of laughter, and there to lift someone else up during the tough times. He was much quicker to welcome than to judge, and had a rare gift for making others feel acknowledged. Even his neighbours became friends.
He packed a lot of living into his 15 years. He thrived on the slopes at Mt Baldy and Big White, loved the ocean, whether surfing or simply playing, and found so much joy at the parks and beaches during Okanagan summers. He drummed with energy, gamed with enthusiasm, loved to camp at mountain lakes and embraced any opportunity to travel. Whether kicking a soccer ball, shooting hoops or just hanging with friends, he brought his full heart.
Sebastian is loved beyond words by his mom and stepdad, Niki & John Wall; his dad, Nigel Martinus; his siblings Cole, Austin, Skyler, and Dylan; his nephews Asher, Weston, and James; his grandparents Sue and Al LaBossiere and Len and Barbara Martinus; aunts, uncles, and cousins and a wide circle of friends who will carry his memory forward with love and stories that will be told for years.
A Celebration of Life will be held in May. Details will be shared soon.
Sebastian lived big. He loved hard. And even though he’s gone, he’ll always be here — in waves, in snow, in laughter, and in every goofy grin we see in the people he loved.
In lieu of flowers, please consider donations to Foundry Kelowna in Sebastian’s honour.
