Philemon Island[3] (French: Île Philemon) is a former artificial island in the Hull sector of Gatineau, Quebec, Canada.

[9] Businessman Ezra Butler Eddy bought the island in 1870 and built a large sawmill there.

[10][4] The E. B. Eddy Company owned several industrial buildings on the island, which were taken over by Domtar in 1998 when it bought E. B.

[4] The channel between the island and the Hull mainland was filled in with "indifferent rubble"[9] during the early 1970s.

[11][12] In the late 2010s, the O Condominiums were built on the former island, as part of the larger Zibi development, an ongoing redevelopment project of the Chaudière Islands.
