Éliel Bureau-Lafontaine

In 2005,  Eliel Bureau-LaFontaine graduated from the 3 years long adventure tourism diploma from the CEGEP de la Gaspesie et des Iles, Quebec. 

Eliel since spent the past 16 years developing my guiding skills in a variety of disciplines including Expedition Sea Kayaking and River Canoeing, Back-backing, Mountaineering, Rock Climbing and Skiing.

The desire to expose himself to pristine remote wilderness regions brought Eliel to the Yukon territory where he spent 6 years leading multi weeks exploratory expeditions in the Yukon, Alaska, NWT and Northern B-C’s Wilderness. During his time off, he would go on solo expeditions, would take a plane to climb summits of the Andes and Himalayas or would hike up to the Bugaboos and climb or develop new routes on alpine granite faces.

Some of the notable trips Eliel has done in the past include the 36 days solo winter traverse of the Gaspe peninsula when he was 19 years old, a month-long winter solo retreat along the arctic circle and the fastest known traverse of the Juneau Icefield from Atlin to Juneau.  Over the past few years, he also opened multiple first ascents and ski descents in the Yukon territory, NTW and northern BC, Skied Fairweather (Highest Summit of BC) and climbed multiple difficult long climbs on remote alpine granite walls. 

Now 14 years after Eliel became an avalanche professional, he works with MSAA as a CAA 2, Apprentice Ski Guide and Apprentice rock guide. You will find him on AST, crevasse rescue or ski mountaineering courses as well as guiding around the sea to sky corridor and the Coastal ranges.

Eliel is an extremely positive, high energy and charismatic guide who has dedicated his entire professional career to make your outdoor dreams come true.
