1906 Port Arthur Utilities Cover, Thunder Bay

A 1906 manhole cover from the former Port Arthur Public Utilities Commission, now part of Thunder Bay’s unified public works system. Before amalgamating with Fort William in 1970, Port Arthur operated its own water, sewer, and electrical services, reflecting the industrial ambitions of this Lake Superior port. Cast in iron more than a century ago, the cover remains a tangible remnant of early municipal engineering in northwestern Ontario.
