Some of you are asking awesome questions. Here at Timmins Flight service, it's not a tower, just a 24 hr FSS for Timmins and Moosonee during 7 am and 9pm or 1200z to 0200z. Yes headings are assigned via VOR outbound radials and even runway headings, just like radar covered areas. If you fly west, north or east, you're on radar at 8000 feet, and 10 000 feet if you're flying south. So, if there is congestion between one arriving and one departing same directin, normally there is an altitude restriction to not above 4000 until usually 20 + nm outbound. If 2 or more aircrafts are involved, then it's runway heading, OR CTR assigned heading in non-radar until visual reference by pilots, or until aircraft appears on radar.
