The Town of Constable is on the northern border of the county and is north of the Village of Malone.
An early business opportunity involved "line stores," constructed so part of the shop was in Canada and the other end in the United States, allowing subtle shifting of merchandise across the border without the inconvenience of customs duties.
During the Civil War, draftable men slipped easily across the border to Canada to avoid military service.
The north town line is the international border between the United States and Canada and is the border of Quebec.
New York State Route 122 is an east-west highway in the town. New York State Route 30 intersects NY-122 at Constable village.
