Just yesterday, we met with the president of Air Inuit. The gravel runway poses an issue that requires him to adapt his new Boeing. With the Quebec department of transportation, he's looking for ways to make the runways more solid. I think that they'll end up having to pave the runways.
When paving a runway on permafrost, the impact of the pavement on the temperature of the ground below must be taken into account. Maintenance must also be planned for any cracks. Defects that occur over time must be fixed. All the maintenance machinery, which is completely different, must be considered. It's another matter entirely.
The north has its own specific needs. Traffic is increasing. I imagine that, one day, in Canada, runways will need to be paved in Resolute Bay or other cities and towns to accommodate increased traffic, but likely also to support the country's strategic interests.
