How do you develop quality canter before introducing fences?

Developing a quality canter before introducing fences is the most important foundational investment in a hunter jumper horse's training, because the quality of the canter determines the quality of every approach to every fence throughout the horse's competitive career — and time invested in developing a genuinely quality canter before jumping begins pays dividends across the entire subsequent training program. The primary qualities to develop in the canter before jumping are rhythm, balance, and adjustability — three interconnected qualities that together produce the canter from which excellent jumping naturally follows. Rhythm development requires riding the canter consistently on large figures — circles, diagonals, serpentines — with specific attention to whether the pace varies on straight lines versus corners, whether the horse speeds up without reason or slows without being asked, and whether the beat of the canter is genuinely three-beat and regular. A rhythmically inconsistent canter will produce inconsistent distances to fences regardless of how much jumping training follows, making rhythm correction a higher priority than fence introduction. Balance development in the canter comes primarily through transitions — the same transitions between and within gaits that develop canter quality for dressage also develop the canter quality that hunter jumping requires. Canter-to-trot and trot-to-canter transitions that ask the horse to shift weight and reorganize its balance develop the half-halt responsiveness that allows the rider to balance the horse before fences. Adjustability — the ability to lengthen and shorten the canter stride within a consistent rhythm — is developed through within-canter transitions and is the quality that allows the rider to meet fences on correct distances rather than accepting whatever distance the unmanaged canter produces. A horse with genuinely quality, adjustable canter before jumping begins will learn to jump courses significantly faster than one whose jumping training must simultaneously develop both jumping skills and canter quality.
