What was the security incident at Calgary airport today?

Details of RCMP investigation on March 12, 2025

  • RCMP was called to investigate a security incident at Calgary International Airport on March 12, 2025 (CityNews Calgary)
  • The incident involved a WestJet flight (CityNews Calgary)

On March 12, 2025, RCMP officers responded to a security incident at YYC involving a WestJet flight. The nature of the threat was not publicly detailed, but the response was coordinated between airport security and law enforcement. No major disruptions were reported, and the RCMP handled the ground-level investigation without air support.

The implication: This incident set a baseline for YYC’s capacity to manage security threats on the ground—a capability tested again more severely in September.

WestJet flight involvement

  • The WestJet flight was the subject of the RCMP investigation on March 12, 2025 (CityNews Calgary)

The RCMP investigation focused on a single WestJet aircraft. The airline cooperated with authorities, and the aircraft was cleared after the investigation. The quick resolution demonstrated YYC’s capability to handle isolated incidents without escalating to military involvement.

What to watch

The RCMP’s ability to investigate and clear a WestJet flight within hours on March 12 suggests ground-level procedures are effective—until a threat jumps to the airspace.

What caused the fighter jet escort at YYC?

Bomb threats on three commercial flights

  • Three bomb threats were made against commercial flights on September 15, 2025 (CityNews Calgary)
  • The aircraft were passenger planes flying from Germany to Calgary (CityNews Calgary)

On September 15, 2025, at around 2 p.m., authorities received reports of bomb threats aboard three commercial passenger aircraft en route from Germany to Calgary. The threats triggered a coordinated response that escalated rapidly—from Calgary police on the ground to NORAD fighter jets in the air. All three planes landed safely at YYC, and passengers disembarked without incident (CityNews Calgary).

NORAD response and military aircraft scramble

  • NORAD scrambled Canadian CF-18 and U.S. F-15 fighter jets, along with refueling aircraft (CityNews Calgary)
  • NORAD responded out of an abundance of caution shortly after 2 p.m. (CityNews Calgary)

The North American Aerospace Defense Command (NORAD) confirmed it scrambled Canadian CF-18 and U.S. F-15 fighter jets, accompanied by refueling aircraft, to escort the three planes (Global News). The response was triggered by reports of bomb threats. NORAD later determined the threats were not credible (CityNews Calgary). Canada’s defence minister praised NORAD’s swift and coordinated response (Global News).

The trade-off: A swift military response ensures aviation safety, but the deployment of fighter jets over a major Canadian city raises questions about how threats cross the threshold from law enforcement to military jurisdiction.

The catch

Three bomb threats in a single afternoon triggered a NORAD intercept, but all threats were later deemed not credible—raising questions about the reporting and vetting process that triggered a military response over Calgary.

Was Calgary airport shut down today?

Operational impact during security incidents

  • Calgary Airports confirmed law enforcement responded (CityNews Calgary)
  • Temporary operational adjustments were made during the response (CityNews Calgary)

During the September 15 incidents, Calgary police were called to the airport around 2:20 p.m. and remained on scene investigating (CityNews Calgary). The airport issued public statements requesting patience as law enforcement worked. While the airport did not fully shut down, some flights experienced delays and operational adjustments. Calgary police confirmed there was no risk to public safety at the time of their statement (CityNews Calgary).

Passenger delays and flight disruptions

  • Public patience was requested by Calgary Airports during the response (CityNews Calgary)

Passengers faced delays as aircraft were held and escorted. The RCMP took over responsibility for the file after the immediate airport response (CityNews Calgary). For travelers, the key takeaway is that YYC remained operational—but security procedures temporarily slowed movement through the terminal and airspace.

Why this matters: For the traveling public, knowing the airport stays open during threats helps reduce panic, but delays can cascade across schedules.

Who is investigating the security incident at Calgary airport?

RCMP role and authority

  • RCMP leads investigations of ground incidents at YYC (CityNews Calgary)
  • Calgary police initially responded on September 15, then transferred to RCMP (CityNews Calgary)

The Royal Canadian Mounted Police (RCMP) is responsible for investigating the March 12, 2025, WestJet incident and took over the September 15 bomb threats file after the initial police and NORAD response. Calgary police assisted on the scene, but the RCMP assumed lead authority for the ongoing investigation.

Coordination with Calgary Airports and NORAD

  • Multiple agencies collaborated on the September 15 response (Global News)
  • NORAD’s role is airborne threat response, RCMP handles ground investigation (CityNews Calgary)

The response on September 15 demonstrated a clear operational split: NORAD handled the airborne intercept and threat assessment, while the RCMP took over once aircraft were on the ground. Calgary Airports Authority coordinated terminal operations and public communications (CityNews Calgary). This interagency cooperation ensured a unified response.

The pattern: A ground incident stays with RCMP; an airspace threat escalates to NORAD—but both are required for comprehensive security at a busy international airport.

Bottom line: Calgary International Airport (YYC) experienced a significant escalation in security incidents in 2025—from a single RCMP-investigated WestJet flight in March to a multi-aircraft bomb threat and NORAD fighter jet intercept in September. For travelers: the airport remains operational during threats, but delays are likely. For authorities: the lesson is clear—threats can shift from ground to air within months, requiring seamless RCMP-NORAD coordination.

For travelers and aviation authorities in Canada, the 2025 incidents at YYC reveal a clear escalation pattern: ground-level threats can rapidly evolve into airspace emergencies requiring military intervention. The consequence for airport operators is clear: invest in threat-vetting processes that can prevent bomb threats from reaching the cockpit, or accept that NORAD fighter escorts become a regular feature of landing at YYC.
