Ground sumac, where to buy?

[80s child]

Where can I buy ground sumac in the GTA?

I've looked for it at regular grocery stores such as No Frills, Price Chopper, Walmart, as well as at bulk spice/dry goods stores. It seems to be a relatively rare spice in Toronto, rarer than things like five spice powder and garam masala.

I've seen ground sumac being sold at some of the higher end stores, such as Costco, Dominions, Loblaws, etc.

Middle Eastern grocers. There are many along Lawrence Ave west of Warden - you can definitely find it at Nasr Foods.

While you're there go to Farhat in the same plaza and get a 2 for 1 Shawarma.

Arz sells it, Nasr should as well, they are both on Lawrence west of Warden.
