I don't have a list but if you contacted Nita
she might be able to help you.
Although the Edmonton show usually gets pretty good attendance, there are not as many vendors as the Calgary show. It's mostly local breeders, but people around here are breeding & selling more & more each year.
The Edmonton shows usually have a fair amount of stuff that is just there to be shared. Rather than just a bunch of young animals that are for sale.
Weather or not you will be disappointed depends on what you are expecting.
