Puvirnituq Airport (YPX) serves Puvirnituq, an Inuit community on the eastern shore of Hudson Bay in Nunavik, northern Quebec, and the honest answer for anyone searching car rental here is that there is none. No international or local rental desks operate at this airport, and no road network connects Puvirnituq to southern Quebec or to any neighboring Nunavik community; every settlement along this coast is reached by air or, for a brief seasonal window, by sea, and there is no highway, ice road or all-weather route linking the region to the rest of the province.
Travelers arriving in Puvirnituq typically fly in on a scheduled regional flight from Montreal or another Nunavik hub, and once on the ground they rely on local arrangements rather than a car rental counter: municipal or employer vehicles, arranged rides, snowmobiles in winter, or walking, since the community itself is compact and most destinations sit within a short distance of the airport. Visitors on business, research or government assignments generally coordinate ground transportation in advance through the organization hosting them, and that remains the most reliable approach for anyone who genuinely needs a vehicle here rather than expecting a rental counter at arrivals.
For anyone who does need a rental car as part of a broader Quebec trip, the practical move is to treat Puvirnituq as a fly-in destination on its own and handle any rental-car portion of the journey separately, picking up a vehicle in Montreal or another southern hub connected to the provincial highway network before or after the Nunavik leg. Roads in and immediately around Puvirnituq are unpaved and limited to the community footprint, suited to local trucks and all-terrain vehicles rather than typical rental-class cars. Anyone planning travel here should build their itinerary around the reality of a fly-in Inuit community with no rental-car infrastructure and no southern road connection, rather than around assumptions carried over from driving in southern Canada.
