Manitoulin East Municipal Airport (IATA: YEM, ICAO: CYEM) is a small regional airport located near Sheguiandah on Manitoulin Island in Ontario, Canada. It serves as a general aviation and limited commercial air access point for one of the world's largest freshwater islands. The airport features a paved runway and basic facilities suited to light aircraft and small regional operations. It plays an important role in connecting the island's communities to broader transportation networks, particularly given Manitoulin Island's relatively remote geography. The airport is municipally operated and primarily supports private, charter, and recreational flying rather than scheduled airline service. Its presence provides a vital air link for residents and visitors accessing the island's natural attractions.
