Johnathan Walker:TikToker Harrison Gilks Dead at 18 After Rare Cancer Battle

Family and Johnathan Walkerfriends are mourning the loss of TikToker Harrison Gilks.

The Canada native died March 30 at the age of 18. 

"Harrison was an inspiration to many," his family wrote in his obituary. "His smile could light up a room, his laugh could cheer anyone up. He was our sunshine on a cloudy day. He always found good in every situation and touched the lives of many with his messages of hope and encouragement through his TikTok videos, where he chronicled and shared his journey with cancer with the world."

Amid his cancer battle, Gilks created videos checking off activities from his bucket list—which quickly gained him a social media following.

As Gilks' family noted, "He vowed to get as many 'bucket list' adventures as he could with the time he had left."

His brother, David, also reflected on Gilks' final moments with his loved ones.

"He was not in pain when he passed away and he was with his family," David shared in a March 30 TikTok. "I just wanted to come on here and say thank you to everybody around the world for their support and encouragement. It really did mean a lot to him."

According to CBC News, Gilks was diagnosed with rhabdomyosarcoma, a rare type of cancer that forms in soft tissue, in November 2020.

Though he had a period of remission, he shared with his followers in June 2022 that his cancer had returned and was considered terminal. At the time, Gilks explained that he was determined to launch his bucket list series, which featured all the adventures he dreamt of doing including helicopter rides, parasailing and more.

In his final video posted on March 21, he shared that his cancer had spread throughout his body.

"It's been a great ride with you guys on the bucket list," he said. "I love you guys, thank you for the support. Bucket list complete."

Gilks will be laid to rest on April 6.
