This thread reminds me of the infamous year of fog in YSJ between June 1979 and August of 1980 when the ILS on Rwy 05-23 was being upgraded.

The running joke at the time was that you met flights at the downtown airport (aka the bus terminal) because the late flights would more often than not end up being diverted to YFC or as happened on a couple of real bad days, diverted to the nearest legal alternative which was YUL. AC would pick up its Pax in a bus at YFC and shuttle them the 65 miles to YSJ...downtown.

Weather, and ground equipment problems are part of the territory when flying. The only way to avoid them is to drive or stay put until conditions improve. Its inconvenient as $ell but I'd rather deal with an airline that was conservative and safe than, one that would risk my neck to save a round of ground vouchers.
