Ford, grandson of former Masters champion Doug Ford, was deadlocked with fellow American Patrick Moore at 10-under after 17 holes at Barefoot Resort's Pete Dye course and both players found trouble left off the tee on the par-4 18th.
Moore found the water on the final hole and eventually made double bogey while Ford was about two feet from the lake. Standing with a leg in the water, Ford pitched out to the middle of the fairway then knocked a 96-yard wedge to less than two feet to secure his first Canadian Tour victory and $24,000.
Moore, David Faught of South Africa and Americans Dave Christensen and Jess Daley tied for second at 8-under. It was the fourth second for Moore in his 15 events played since he joined the Canadian Tour at the start of the 2000 season.
Five players had a share of the lead at 10-under early on the back nine but Faught and Moore emerged as the front runners and were deadlocked at 11-under after 14.
However, both bogeyed the tough par-3 15th and then Faught drove his tee shot on the par-5 16th into a hazard and bogeyed his second straight to drop to minus nine.
Ford, meanwhile, also bogeyed 15 but regained a share of the lead with Moore at 10-under with a birdie on No. 16. He then knocked a 7-iron long and left on the par-3 17th and saved par with a 10-foot putt to remain deadlocked with Moore on the final tee.
