429 Transport Squadron of the Royal Canadian Air Force is one of four squadrons attached to CFB Trenton in Trenton, Ontario.

The squadron was originally formed as a bomber squadron of the Royal Canadian Air Force (RCAF) attached to RAF Bomber Command during the Second World War.

The final move was in 1990 to 8 Wing in Trenton, Ontario.

Two years later in August 2007, 429 Squadron was again re-activated, this time operating the CC-177 Globemaster III strategic transport aircraft.

It used these new aircraft in support of Canada's operations in Afghanistan.
