I live in St George and work in SJ, so I kinda know your plight.
Barley malt & vine's your best bet for keg and carboy supplies. getting yeast and grain though, best bet is freddy for the yeast, get in on the orders for grain that FCBA do or order from noble grape in Halifax. I've contacted the Big Tide Brewery about getting in emergency supplies if needed, and the brewmaster theres been kind about it and said she'd see what she could do.
