It is always interesting that YHZ Airport Authority can find money for a shinny new terminal but no money for proper airport navaids, and they are not alone in Canada.
I suspect that runway 32 was not available as it had not been cleared of snow, the airport operations mgr. would make that decision.
The weather was horrible and the strong wind gust at the approximate time will likely be a factor. I have flown into YHZ in really crappy weather and it is not a great airport in winter storms. Too many holes in the swiss cheese model for an accident last night.
