ISO curing salts (sodium nitrate/nitrite) in the toronto area

Hi all,

I've been on the hunt for meat curing salts and it appears nobody in the Kensington Market area carries any. I also checked several chinese grocery stores along Spadina and they all seem to carry a particular brand of curing salt that already contains sugar and other aromatics.. I just want the plain curing salts so I can try my hand at making my own pancetta.

The one good thing I found out is that they sell sausage casings at the big butcher shop in Kensington market.

Anyone know where I can get some curing salt?
