I have an answer for your question. The committee did a report on that, but it was from the Office of the Auditor General.
There was a report tabled in 2017. The OAG identified 117 airports that serve remote and northern communities, which are defined as “communities for which the only reliable year-round mode of transportation was by air.”
We're talking about 117 out there. Maybe there are more or maybe some are under the rising sea, but there were 117 airports at that time.
