Ryker Gamble and Alexey Andriyovych Lyakh - half of Vancouver-based "High on Life SundayFundayz", a group of travel video bloggers on YouTube - died Tuesday after they fell into fast-moving waters at the falls.
The trio were in their late 20s to early 30s, according to Canada's National Post.
Vancouver YouTube star Ryker Gamble has been identified as one of three young adults who died after slipping into the river above Shannon Falls on Tuesday. "Your bright personality will be greatly missed", one person posted on Facebook.
They landed in a water pool about 30 metres below, triggering a desperate rescue effort involving police, firefighters, paramedics and search crews from Squamish and Lions Bay.
Underwater dive teams worked hard on Wednesday undertaking a "complex recovery" of the bodies from a hard-to-access pool, according to an RCMP release.
The adventure group's core members were a trio consisting of Gamble, Lyakh and a third surviving friend.
The travel and vlogging communities are mourning a major loss as it has been revealed that three of the "High on Life" YouTube travel vloggers passed away after they slipped and fell during a hike at a Canadian waterfall.
Gamble, Lyakh and another group member, Justis Price Brown, made headlines in 2016 and earned bans from USA federal lands after they participated in an out-of-bounds excursion on a sensitive hot spring in Yellowstone National Park.
RCMP Cpl. Sascha Banks says pools at the falls are not accessible by side trails, so teams are trying to figure out how to recover the bodies.
Until the recovery operation is complete, Shannon Falls and any trails leading to the pool system will remain closed to the public, authorities said.
In recent years, he also worked as an instructor in a business that aims to teach people how to build a popular account on Instagram.
"Unless you have the knowledge of that area, the expertise and the right equipment you should not be up there", Banks said. "And with more volume comes more responses".
