What is the current status of the Delta plane crash investigation in Toronto?

According to Toronto airport officials, all but two of the injured passengers from the Delta plane crash have been released from the hospital.

Aviation investigators from both Canada and the United States are now collaborating to determine the cause of the accident. While officials acknowledge the challenging weather conditions that affected flights over the weekend, they emphasize it's too early to determine if weather played a role in the crash. The investigation remains ongoing.
