Here in sunny Calgary, we are lucky to have one of (if not THE) largest Wargames shop in the entire world: Sentry Box. Just shy of 14,000 square feet of shop. An old factory, with a mezzanine entrance level, with gaming space; an upper (probably former office space) for historicals only (!!!), the main space is GW, paints, RPGs, novels, many other miniature levels. It’s a staggeringly neat experience to go there. Oh, and they have a separate cards shop next door (thankfully, as the card types were at the low end of hygiene

).
And then there’s OTHER independent shops: Ogre’s Den, Imaginary Wars (run by an ex-GW staffer); an actual GW store in the big posh mall (with a manager that is one of the longest timers in ALL of GW); and a few others.
Mind you, Calgary is not transit friendly, and is one of the most spread out cities, so most shops are like 20km driving from my hood. Still worth the drive for most.
But good luck to your new shop!
