"Mizuno says only 3% of USA golfers are LH and close to 20% of Canadians due to Hockey.."

Legend has it the highest percentage of lefty golfers in the world is in the area around Kingussie-Newtonmare in the Scottish Highlands, where the game of shinty (a field hockey-like game) is very popular.
From David Owen's 2007 article in Golf Digest:
"When we had finished, we had a drink with a group of regulars sitting at two picnic tables outside the clubhouse. One of them told me, "Kingussie has more left-handed and cross-handed players than any other golf club in the world" -- a consequence, he said, of the town's intense devotion to shinty, a bruising Highlands stick game that is similar to the Irish sport hurling (from which it evolved) and to field hockey, and in which there is a tactical advantage to playing from the wrong side of the ball, apparently. No, no, another member insisted: There are more left-handed golfers in Newtonmore, Kingussie's principal shinty rival, three miles to the west. The conversation then veered into a discussion of Newtonmore's golf course, which my new friends unanimously dismissed as too flat to bother with."
