1906 Port Arthur Public Utilities Manhole Cover, Thunder Bay

This cast iron manhole cover, dated 1906, originates from the Port Arthur Public Utilities Commission. Before the amalgamation of Port Arthur and Fort William into Thunder Bay in 1970, Port Arthur independently managed its water, sewer, and electrical services. This cover is a testament to the early municipal engineering efforts in northwestern Ontario, reflecting the city's industrial growth as a significant Lake Superior port. It remains a functional part of Thunder Bay's integrated public works system.
