We Remember
MARTINUS, Sebastian William
April 15, 2010 — April 24, 2025
A Celebration of Life to honour Sebastian will be held on Monday, May 19, 2025, at 2:30 PM, at Emmanuel Church: 2600 Hebert Rd, West Kelowna, BC
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.
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

I remember sebastian from before I moved away from town 5 years ago. I moved back recently and was downtown on the night everything happened. He came up to me asking if I could boot for him. I said no and he seemed bummed and looked at him and said “seb?” He didn’t recognize me which makes sense how long it had been. As soon as I said my name He gave me a hug. I’m gonna miss him. Definitely the life of the party and a lovely person to be around and have in your circle. May you rest in peace and I hope to see you again one day. Irreplaceable soul you had.
We love you Seb, Niki, John, Nigel and Cole and you are forever in our hearts 💜 Seb you are a hero – I am sorry the world let you down. 💙
I wasn’t super close to Seb but I knew him from grade 6 (i’m in grade 9 now) I remember how last year he came to my school just for fun and saw me sitting in the hallway and he just said “what’s up cat how have you been?” I hadn’t talked to him in so long and i didnt even recognize him but he still said hello to me. I was with him a week before he died and he just brought joy to everyone around him, He was full of laughter and smiles, always making sure no one felt left out🤍 He was taken too quickly, LLS🤍
he was such a sweet soul i just wish i was there for you that night. i just hope you the best rest well sebastian LLS 🤍🕊️
Sending Prayers and love to your family. May you and your family hold loving and fond memories of Sebastian in this heart breaking time. Words cannot express the depth of loss in losing such a dear child. May your memories, in time, bring you comfort for the time Sebastian blessed your life.
I hope you get this message. Peace and love ❤️

I wasn’t close friends with seb but we were still friends. He was the sweetest guy ever and always had a smile on his face, I’ll miss singing Umbrella by Rihanna with him and everybody else on the bus, that song will forever remind me of seb. He always brought a smile to everyone’s faces even when they were sad. I’m gonna miss seeing you seb. LLS
I may not have known seb for years and we may not have been together 24/7 but he was kind in every way you could think of, always there when someone needed him, he was funny, always knew how to make someone laugh. I miss him so much but I know he’ll fly high.
LLS🕊️🕊️❤️
I only knew Sebastian for a little over a year and every interaction I had with him he was always a kind and sweet one, he had such a kind heart and I just remember hanging out with him downtown and we would all just chill out and talk and yap about random things and we would laugh. He was such a kind soul and he didn’t deserve to leave this early if I could do anything to have him back on earth I would do it. I bet. His whole family is having such a hard time with this and I completely understand I respect them,
My condolences, Brooke Moore
Your beautiful boy will be deeply missed and never forgotten by so many. I truly enjoyed his kind and cool character. I will miss my supervision side-kick. My heart goes out to all who knew and loved him. You did an amazing job of honouring Sebastian today. May peace find you in the coming weeks and months. Mrs. Holmstrom
