Incident: Westjet B738 at Halifax on Jan 5th 2020, overran runway on landing

A Westjet Boeing 737-800, registration C-FUJR performing flight WS-248 from Toronto,ON to Halifax,NS (Canada) with 172 passengers and 6 crew, landed on Halifax's runway 14 (length 7,700 feet/2350 meters) at 12:07L (16:07Z), tower advised RVR was 4000 feet, braking action was not known for runway 14, 100% wet snow. After roll out the crew advised they weren't sure whether they had stopped still on the runway or were beyond the end, airport operation dispatched a vehicle to check the position of the aircraft. The aircraft was found past the end of the runway. The crew shut the engines down (with APU running), reported no injuries on board and requested to be towed to the apron. The passengers disembarked via mobile stairs at the end of the runway and were bussed to the apron. Tower advised departures on runway 05, that all emergency services were occupied and no cover was available for the departures. Tower told operations and emergency vehicles that the aircraft was at the threshold of runway 32 (at the end of runway 14). Pictorial evidence suggests the aircraft came to a stop with all gear off the paved surface of the runway end safety area. The Canadian TSB have dispatched a team of investigators "following a runway overrun" at Halifax.
