Key Lake Airport — Key Lake, Canada

Key Lake Airport, designated YKJ, is a remote airstrip in northern Saskatchewan, Canada, built primarily to serve the Key Lake uranium mine, one of the world's most significant uranium mining operations. The airport exists almost exclusively to support industrial logistics, transporting mine workers, equipment, and supplies to and from this isolated site in the Athabasca Basin region. YKJ lacks scheduled commercial passenger service, instead operating through charter flights coordinated with mining company schedules. Its gravel runway and minimal infrastructure reflect its single-purpose industrial function rather than any tourism or civic role. Key Lake's airport underscores how northern Saskatchewan's resource economy depends heavily on dedicated air transport links.
