My feed is the southern half if the Noranda sector, from Montreal centre. I have listened to the CYFB feed and noticed an unsteady period of northern Quebec being cross-coupled with my feed and other times, both airspaces are divided in half during their peak periods. My feed includes all high level traffic at FL 290 and above, for Timmins, Moosonee, Val D’Or/ Rouyn, among other sectors. I have seen some pictures of the Montreal controllers for the Timmins-Noranda sector, with their communication panel showing 9 frequencies.
