They're about 1/3 full in most arenas they play (5k in Calgary 14500-15000 is a sellout for most concert set ups there), so the chances they return to a northern Canadian city to make up a show in front of a mostly empty arena are slim to none.
Only way is if the illness is bad enough they miss the rest of their Canadian tour as well. But considering they play Saskatoon tonight and have not cancelled yet, I'd imagine they're back on track.
