It's at any time of day. The frequency varies. I haven't noted down all the days, but I've taken samples. This could easily occur 60 times a day, until 11:30 p.m.
There are also propeller aircraft, such as the Citation Sovereigns and Dash 8 Q300s and Q400s, which fly to Kuujjuaq, Chibougamau, Sept-Îles and the city of Quebec. They all pass very close to the houses.
