Safest option is stay put. But if freezing levels are low over the land, but you have VMC, you could, (if you wish) stay low level and follow lake Melville and the Hamilton Inlet all the way from Goose Bay to the Atlantic coast. You even have a diversion airfield at Rigolet. (Used to do that run on a regular basis when I was flying from Goose Bay - long before GPS and moving maps)
Take care !
