Pennsylvania Has No Water Border with Canada

Pennsylvania Has No Water Border with Canada

Correct. Pennsylvania is a landlocked state—it does not touch any of the Great Lakes, the St. Lawrence River, or any other international water boundary.

Pennsylvania’s Borders

• North: New York (land border, 42° N parallel).
• East: New Jersey (Delaware River — but NJ opposite, not Canada).
• South: Maryland, West Virginia, Delaware (Mason-Dixon line, etc.).
• West: Ohio (meridian line).

Nearest Water Border to Canada

• Lake Erie: Pennsylvania has a 51-mile (82 km) shoreline on Lake Erie (Erie County), but the international boundary runs through the middle of the lake—so PA’s waterfront is domestic. The US–Canada line is offshore.
• New York, Ohio, Michigan, Minnesota have actual water borders with Canada (Great Lakes, St. Lawrence, Rainy River, Lake of the Woods).

So: Pennsylvania touches Lake Erie, but no direct water boundary with Canada.
