Roberval Airport — Roberval, Canada

YRJ denotes Roberval Airport, situated on the shores of Lac Saint-Jean in Quebec's scenic Saguenay-Lac-Saint-Jean region. The airport primarily handles general aviation, forestry patrol flights, and recreational traffic tied to the lake's popularity for boating and fishing. Roberval has historical aviation significance as a former seaplane base and training site, and the surrounding area hosts the famous Traversee internationale du lac Saint-Jean swimming event each summer, drawing visitors who may arrive via YRJ. Without scheduled commercial service, the airport instead functions as a community asset supporting charter flights, private pilots, and emergency access for this lakeside town of roughly ten thousand residents.
