 It is owned and operated by the City of Castlegar, and has a 15317 sqft passenger terminal.

 The airport is therefore certified for day operations only, and the glideslope on approach is set to a steep 5.0° rather than the standard 3.0°.
 The instrument approaches to Castlegar are considered among the most challenging of any in use at a commercial airport in North America.
 As of 2011, the Dash-8s serving the airport required minimums of 3400 foot cloud ceilings and three miles visibility (Air Canada Jazz adds 100 feet and one mile to these minimums).
