Sonnie Trotter (born November 15, 1979 in Toronto, Ontario) is a Canadian professional climber, known for his strength in many rock climbing disciplines, contributing to hundreds of first ascents around the world. Trotter began climbing in 1997 at age 16, and soon became the first Canadian to climb 5.14c the third North American to have established a 5.14d route. In more recent years, Trotter has gained notoriety for his support of clean trad routes over bolted routes, and his first ascent of the Cobra Crack in Squamish, British Columbia.
Sonnie also made Squamish history in 2006 when he and his climbing partner Matt Segal connected The Shadow 5.13b, The Grand Wall 5.13b and The Black Dyke 5.13b on the Stawamus Chief all free in a single 12-hour push.
