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.

Seb was one of my homies even though i didnt see him all that much i will never forget the kindness and true friendship he held to his heart for every one of his friends. LLS🦢❤️
I had the most fabulous experience knowing Sebastian, His smile when he approached,, his love ad passion for life his amazement of my toys and how eager he was to learn about them.. Always respectful, caring, interested, loving and fun to be around … we shared many laughs together and I always looked forward to the next time I would see him. We were planning to fly model plans together and I offered to teach him all I knew about fishing but he said he had never gone but was willing to go and learn! There ware many topics that we shared in conversations and that could be what I will miss the most … his smile, his presence, his gentle personality and the vast knowledge and wisdom I saw in him that he had gained thru his short life! It showed his love and passion for life and the respect he had for it! Sebastian, my buddy you were taken to soon I will never forget you and I miss you terribly but in my senior years I know my time will come soon enough and I am sure you my best buddy will be there to greet me, to help me and show me the way on to our next journey together! I know our Creator must have very special plans for you! If there is one wish I could ask from our Creator is this …Creator if you have made a mistake …please reconsider and send Sebastian back to us, he is too important to us,, we need him and his love to continue with us here in this life!, Our hearts are crushed without him Love always my friend Hawkeye!
My heart goes out to you Niki & John , plus Nigel and the whole family. Helen told me the other day and a flood of incredible memories flooded my mind. I had great dances and enjoyed some special times over the years with your family . Words alone cannot express the profound sadness I feel for all of you. You have many incredible friends please continue to lean on them to get you through your grief and process this devistating loss. Thank you for sharing you son with all of us, he will be truly missed by many.
Hugs Sincerely your Friend and Sebastian ‘s
