While filming for their adventure channel, three YouTubers tragically fell to their death.

Three young YouTubers behind the popular travel adventure channel High On Life have died after falling at a waterfall in Canada.

According to the Vancouver Courier, vloggers Ryker Gamble and Alexey Lyakh, both 30, died after they jumped into Shannon Falls to save fellow YouTuber and Lyakh’s girlfriend, 29-year-old Megan Scraper, who had slipped and fallen into the falls.

The trio, who were believed to have been filming a YouTube video at the time of the accident, were swimming in the pools at the top of Shannon Falls – the third highest waterfall in British Columbia.

The remaining members of the High On Life YouTube channel posted a tribute video yesterday, saying “they were three of the warmest, kindest, most driven and outgoing people that you could ever meet, and the world has lost a great deal of light with their passing. They lived every single day to its fullest.”

Ryker Gamble’s girlfriend, Alissa Hansen also posted a tribute to the popular vlogger on Instagram.

Grief seems to bring everything to a halt. What was once possible seems irrelevant. The schedule is cleared, the mundane ignored. One moment a wave of catastrophic emotions, the next a cavern of emptiness. Death is not a request to stop living, it is a request for loving. It calls us to see fully what is in front of us. To see what needs healing. To see those for whom our hearts would break if we did not speak the words that need speaking. It asks us to tend to one another. To value this moment here and now. To face our own ephemerality. Death violently shakes us awake, time and time again. Words by @heyheatherobscura. . The only words I have right now to share are from my dear soul sister Heather. May we all send prayers to their souls as they transition.

The High On Life YouTube channel has over 500,000 subscribers and over a million Instagram followers.

In the past, the group has been seen as a controversial influence on teen viewers, as the vloggers often recorded themselves partaking in dangerous activities and adventures.

It’s not the first time a YouTube star has died while filming for a video.

Just weeks ago, 22-year-old American YouTube star Pedro Ruiz III died while filming a vlog with his pregnant girlfriend Monalisa Perez.

In a daring stunt, Ruiz instructed Perez to shoot at an encyclopedia he was holding in front of his chest, in the hopes the video would go viral.

The bullet pierced through the book, killing Ruiz.
