What was happening at Toronto Airport before and after the Delta Flight 4819 crash?

Before the crash of Delta Flight 4819, Toronto Airport was already experiencing a significant backlog due to successive winter storms that had disrupted normal operations. This pre-existing situation complicated the emergency response to the crash landing. In the aftermath of the incident, officials are now warning travelers about the potential for extended travel disruptions. Passengers are being advised that delays and flight cancellations could continue for days as the airport deals with both the ongoing winter weather conditions and the impact of the crash.
