Most Canadians, like most Americans, are naturally right-handed, so the discrepancy has nothing to do with national brain-wiring. And how you hold a pencil, say, has little or no bearing on how you hold a stick. A left-handed shooter puts his right hand on top; a right-hander puts the left hand there.
But none may be so simple as how one holds a hockey stick. According to sales figures from stick manufacturers, a majority of Canadian hockey players shoot left-handed, and a majority of American players shoot right-handed. No reason is known for this disparity, which cuts across all age groups and has persisted for decades.
