English: As seen in July 2015, overlooking the Sault Ste. Marie Canal in Sault Ste. Marie, Ontario, Canada is the former canal superintendent's office, an almost anachronistically late-period example of Second Empire architecture that sets itself apart with unusually heavy massing for the style; as with other buildings on the site, its exterior walls are of randomly coursed blocks of locally quarried sandstone finished in smooth-textured limestone trim. Nonetheless, most of the style's other trademarks - façadal symmetry, arched windows, copious Classically-inspired detail, and of course, a mansard window pierced by a pedimented central dormer - all make their requisite appearances. Under the ownership of Parks Canada which operates the canal as a historic site, the building continues in its original function as administrative offices. The canal itself stretches about a mile in length between Whitefish and Saint Mary's Islands, and was built in 1895 to replace an earlier facility that had been destroyed in the War of 1812. A smaller, more northerly alternative to the Soo Locks that lies fully within Canadian territory, the impetus for the canal's construction was an 1870 incident in which Colonel Garnet Wolesley of the British imperial army, in charge of an expedition to Manitoba to quell the ongoing Red River Rebellion, was refused passage through the other canal by American authorities who were angered by his support for the Confederacy during the U.S. Civil War. The canal's original lock, decommissioned in 1987 after the collapse of one of its walls, is notable as the first in the world to be powered by electricity, which was generated onsite in the powerhouse.
