The flag of the 409 Combat Support Squadron (RCAF) flies on a light air-force blue field, a colour traditionally associated with air arms throughout the Commonwealth, signalling immediately that this is an Air Force unit flag. At the upper hoist (canton) sits the familiar RCAF roundel: a dark blue outer ring, a white disc, and a stylized red maple leaf at the centre. This roundel anchors the flag in the national air force identity, much like the RAF’s red-white-blue roundel does for British squadrons. Its placement in the canton functions almost like a national jack on a naval ensign—asserting service, nationality, and branch at a glance.

Set well to the fly side is the squadron’s full heraldic badge, crowned with the St. Edward’s Crown to denote service under the Canadian monarch. Within the RCAF’s standard circular badge frame and gold laurel wreath appears the unit’s distinctive device: a black cloak (sable) with blue lining, over which is laid a gold crossbow. Beneath, on the scroll, is the Latin motto “MEDIA NOX MERIDIES NOSTER”—“Midnight is our noon.” Together, cloak, crossbow, and motto encapsulate the unit’s night-fighter origins (the squadron was formed in 1941 as No. 409 Night Fighter Squadron) and its emphasis on stealth, vigilance, and precision. Even though the squadron’s role and designation have evolved over time, that heritage remains central to its identity and is preserved through the badge.

The crown atop the badge is an important constitutional marker: Canadian military badges that bear the Crown do so to indicate that the unit serves the Sovereign, reflecting the constitutional monarchy framework of the Canadian Armed Forces. The gold wreath framing the badge signals honour and achievement, a visual cue common to RCAF squadron crests.

After World War Two, the squadron was reactivated during the Cold War as an all-weather fighter unit, later transitioning through various roles, including tactical fighter operations and, more recently, combat support. Today, 409 Squadron is based at 4 Wing Cold Lake, Alberta, and continues to play a vital role in the defense of Canadian airspace as part of NORAD operations.
