Mr Burton said the catch, which was nearly three times heavier than his previous record of 10lb, was "a struggle to lift for the photographs".
He said he "never thought he'd catch anything this big. This is truly the capture of a lifetime, and even more so from the canal."
The pike was returned to the canal for others to catch "if they're lucky enough", Mr Burton said.
According to the Canal and River Trust, a 37lb (16.8kg) pike was caught from the Gloucester and Sharpness Canal in 2004 while a 42lb (20kg) pike was caught from Northamptonshire's Boddington Reservoir in 2010.
