Amazon.ca is way overpriced and a crap shoot. I sent you a private message with a list from Moto Canada's PR firm where what should be available for purchase through carriers. Sent it after reading your comment on the software update thread, didn't realize that this thread existed as well.
Hopefully, the carriers smarten up and start selling these like they're supposed to be. Maybe Moto should just start selling them through their website direct to consumer, there really is no need to rely on the carriers for the Moto Mods.
Have a look at Telus online shop again! Choose Shop > Accessories > category ALL, then choose to Filter By Device = Moto Z.
Most or all of the additional items are mixed in with the generic devices which work with other phone in addition to the Moto Z
I see SoundBoost, Projector, and Hasselblad True Zoom at a minimum
