Finlayson Lake Airport (ICAO: CFT3) is a small, remote aerodrome located near Finlayson Lake in northern Ontario, Canada. It serves as a bush flying access point to the wilderness area surrounding the lake, primarily supporting float planes and light aircraft used for hunting, fishing, and forestry operations. The airport is uncontrolled and operates without a control tower, typical of remote Canadian bush aerodromes. It is registered with Transport Canada and serves the sparse population and outfitters in the surrounding region rather than scheduled commercial traffic.
