In the US, citizens in dozens of states directly elect judges, sheriffs, school board members, and district attorneys. In Canada, those positions are mostly appointed by provincial governments. If we define a better democracy as one that gives ordinary voters more direct control over the officials who interpret and enforce the law at every level, the US wins clearly, messiness included. Canada's Westminster system runs more orderly, sure, but it concentrates power in the PM and cabinet, and Canadians have far fewer ballot initiatives, recall elections, or local accountability mechanisms than most American states have.
