There is still in fact a monthly show in Edmonton. Randy Kruk runs the show, but unfortunately there is no website for it. He usually posts it up on FB Marketplace around the week leading up to it.
One key change with it is that it used to be at the Lorelei-Beaumaris Community Hall, but the monthly show has since moved to Fort Saskatchewan's Pioneer House Club 50 (an extra 15 or so minute drive from the original venue, but it is a larger space that is less jam-packed when there are tons of people there). Randy just texted me a couple of days ago informing me that the next show has been rescheduled from Sunday, July 13 to Saturday, July 19.
