I'm pretty new to AoS in Calgary but there are a few places to play and groups playing AoS in Calgary. First, try and join the Age of Sigmar Calgary group on facebook as most events get posted there.
The largest group seems to meet up in the NE at Ogre's Den Gaming on thursday nights. There are some that play at the Sentry Box although I don't really know much about them. Imaginary Wars in the South has AoS nights thursday the month of March for the Dread Solstice campaign. And depending where you live you might want to check out Monster Hobbies in High River. They have a 1000 point tournament going on near the end of the month and have weekly meetings as well.
Um, yeah, that's about what I know, hope it helps.
