A strong winter storm swept across the Prairies on Wednesday. Heavy snow and low visibility hit Calgary hard. Conditions quickly became unsafe for aircraft. Calgary International Airport suspended all flights for several hours.
The airport authority confirmed the decision early Wednesday. Officials said safety concerns led the move. Snow and ice built up rapidly on runways. Crews needed time to restore safe conditions.
“Maintaining a safe operation is Calgary Airports’ top priority,” the authority said in a statement.
Crews Clear Snow and Ice
Ground teams moved quickly after the shutdown. Crews worked to clear runways and taxi areas. Equipment removed snow and treated icy surfaces. The airport paused flights to allow full access.
“In a winter storm, we clear the runways, taxiways and aprons of snow and ice to ensure aircraft can land, take off and taxi safely.”
Officials said extreme weather demands full closures at times. All paved areas must remain clear during clearing work. Snowplows, sweepers, and sanders require open space.
The airport also called in extra staff. On-call crews joined regular winter teams. The added support helped speed up the cleanup.
Flights Resume After Conditions Improve
Airport operations resumed around 2 p.m. Weather conditions showed improvement by then. Officials inspected the airfield before reopening. They confirmed safe conditions for aircraft movement.
All arrivals and departures had faced disruption during the suspension. Some flights experienced delays after reopening. De-icing and final checks continued through the afternoon.
Officials warned delays might still occur. Clearing snow takes time even after storms pass.
Advice for Travellers
Airport officials urged travellers to stay informed. Passengers should check flight status before leaving home. Airlines provide the latest updates directly.
Those heading to the airport should allow extra travel time. Snow-covered roads slowed city traffic. Winter driving conditions added to delays.
“Once here, be patient, as runway clearing and de-icing may create some delays for flights,” the statement said.
The authority reminded travellers about rebooking questions. Passengers should contact their airlines directly. Airport staff cannot adjust individual bookings.
Winter Weather Remains a Challenge
The storm highlighted winter travel risks in the Prairies. Sudden weather shifts often disrupt flights. Airport teams continue preparing for similar events.
Officials stressed safety remains the top concern. Temporary shutdowns protect passengers and crews. Winter operations will continue throughout the season.
