A Delta Air Lines flight from Minneapolis crashed upon landing at Toronto Pearson International Airport on Monday, leaving at least 15 people injured, including three in critical condition. The aircraft, identified as Flight 4819, flipped onto its roof on a snow-covered runway, prompting an emergency response and temporarily shutting down airport operations.

Peel Regional Paramedic Services confirmed that among the critically injured were a child, a man in his 60s, and a woman in her 40s. Two people were airlifted to Toronto trauma centers, while a child was transported to a children's hospital. "All passengers and crews are accounted for," Toronto Pearson Airport stated in a post on X.

The plane, a CRJ-900 operated by Delta's regional affiliate Endeavor Air, carried 80 passengers and crew members. The cause of the crash remains unclear, though heavy snowfall and wind gusts of up to 40 mph were reported in the region at the time. Video footage shared on social media showed the overturned plane with emergency crews working around the wreckage as passengers walked away.

According to Newsweek, The Federal Aviation Administration (FAA) confirmed the incident, stating, "Delta Air Lines Flight 4819, operated by Endeavor Air, crashed while landing at Toronto Pearson International Airport in Canada around 2:45 p.m. local time on Monday, February 17. The Transportation Safety Board of Canada will be in charge of the investigation and will provide any updates."

The Transportation Safety Board of Canada has launched an inquiry into the accident, with officials examining flight data, weather conditions, and possible mechanical failures. Sources told ABC News that an early investigation is already underway, though no immediate explanation for the aircraft's overturning and subsequent fire has been provided.

Passengers aboard the flight described a chaotic scene upon landing. One traveler, identified as John Nelson, posted a video on Facebook showing emergency responders at the scene. "We're in Toronto. We just landed. Our plane crashed. It's upside down... fire departments on site. Upside down. Most people appear to be OK," he wrote.

Toronto Pearson Airport was temporarily closed following the incident, with flight operations suspended until at least 4:30 p.m. Over four dozen flights were delayed or canceled as crews worked to clear the wreckage. The U.S. FAA also issued a temporary ground stop affecting incoming flights.

The Association of Flight Attendants, which represents crew members aboard the flight, issued a statement confirming that there were no fatalities. "Our union is responding to an incident in Toronto with Delta Air Lines Endeavor Flight 4819. AFA crew were working this flight. Reports are there are no fatalities," the union posted on X. "Please do not speculate on this incident as everyone works to gather information and support those involved."

Delta Air Lines has not yet provided an official statement on the cause of the accident. The aircraft, which was approximately 16 years old, typically has a lifespan of two to three decades, according to aviation data firm Cirium. Endeavor Air, which operates regional flights for Delta, primarily uses smaller aircraft, including the CRJ-900, which has a 76-seat configuration.
