Rimouski (Hydro-Québec) Heliport

The closure was due to a change in operational requirements by its owner and sole operator, Hydro-Québec. This is common when a company's logistical needs evolve, such as the completion of a major construction project, consolidation of aviation services at a regional airport (like the main Rimouski Airport, CYXK), or the adoption of new technologies like drones for power line inspections, which reduces the need for a dedicated heliport at this specific substation.

The site is an active Hydro-Québec electrical substation (Poste de Rimouski). While the physical helipad—a paved circle with a faded 'H'—is still visible on the ground via satellite imagery, it is no longer a registered or maintained aviation facility. It is considered permanently closed to all air traffic and is simply a remnant piece of pavement within a secure, active industrial site.

The heliport was a private, special-purpose facility used exclusively by Hydro-Québec. Its primary function was to support the construction, maintenance, and inspection of the high-voltage electrical transmission grid in the Bas-Saint-Laurent region. Operations included transporting linesmen, engineers, and equipment to remote or difficult-to-access towers and power lines, conducting aerial patrols to identify faults or damage, and providing logistical support during power outages or emergencies. It was a vital operational base for ensuring the reliability of the regional power supply.

There are no known plans or public discussions regarding the reopening of this heliport. Given that its operational purpose has ceased and industry trends favor consolidating flights at full-service airports or using unmanned aerial vehicles (drones) for inspection tasks, the prospect of it being recertified and reopened is considered extremely low.
