cafe du monde
I just found a great place to buy sealed tins of Cafe Du Monde coffee with chicory for New Orleans style cold-pressed coffee in Chinatown East, Toronto. It's in the larger grocery store closest to the "Green P" parking lot (sorry can't remember the name!) and at $5.99 it's a bargain compared to other suppliers.

The Spadina Chinatown strip also has a number of stores that carry Cafe du Monde, for anyone who's further west.
Tap Phong and similar stores in that area also sell the little metal filter devices that you can balance on top of your glass to slow-drip the coffee. With the right proportion of sweetened condensed milk I've been pretty successful replicating the Vietnamese-style coffee I've had in restaurants.
