In Ontario, at the mouth of the Thames (not pronounced "Tems" as in England, but "thames" as it's spelled) River near Tilbury.  This light was built as a result of the war of 1812 making it the second oldest light in Ontario.  The lighthouse is on private property, but can be seen from the north side near the boat launch.  Exit off highway 2 and follow the signs to Lighthouse Cove.
