Extension, British Columbia
Extension, originally Wellington Extension, is a community to the south of Nanaimo, British Columbia, Canada, on Vancouver Island.
History
A post office was opened in 1900 with the name "Extension" in reference to the Wellington Extension of the collieries at Wellington, 13 km away. Owned by the Wellington Collieries Company, one of the area's main coal companies, this was originally called "Wellington Extension" until shortened to "Extension" when the post office was named.[1]
