Geraldton Greenstone Regional Airport (IATA: YGQ, ICAO: CYGQ) is a small regional airport serving the town of Geraldton and the broader Greenstone municipality in northwestern Ontario, Canada. It provides essential air connections for a community that is otherwise relatively remote, situated approximately 250 kilometres northeast of Thunder Bay. The airport supports both scheduled passenger service and general aviation operations, playing an important role for resource industries and communities in the surrounding area. Its location in the boreal forest region of Ontario reflects the broader pattern of small regional airports serving Canada's northern and remote populations. Ground infrastructure is modest, consistent with the airport's regional scale, and the facility is managed at the municipal level as part of the Greenstone municipal government's responsibilities.
