Sandy Lake Airport — Sandy Lake, Canada

Sandy Lake Airport, coded ZSJ, serves the Sandy Lake First Nation in a remote part of northwestern Ontario, Canada, accessible only by air for most of the year aside from a seasonal winter road. The airport is a critical lifeline for this Oji-Cree community, supporting passenger flights, freight delivery, and medical evacuations that would otherwise be impossible given the surrounding boreal wilderness and lack of permanent highway access. Small regional airlines operate scheduled service connecting Sandy Lake to Sioux Lookout and other northern hubs. ZSJ underscores the essential role that remote airstrips play across Canada's north, where isolated Indigenous communities rely on aviation infrastructure for basic connectivity to the rest of the province.
