What happened to the Delta flight at Toronto International Airport and were there any casualties?

A Delta flight from Minneapolis flipped upside down while landing at Toronto International Airport yesterday afternoon. Remarkably, all 80 people aboard the aircraft survived the incident, with everyone making it out alive. Airport officials noted that the area had experienced an unusual amount of heavy snowfall in the week leading up to the incident, which may have been a contributing factor. An investigation is currently underway to determine exactly how the plane ended up on its back during landing.
