Piker,
I still have not heard of anything in or around the GTA (doesn't mean their isn't though) aside from a quick jaunt up to Borden. I bought my mess kit used off of another member of this board some time ago. I have also heard that somtimes you can get the material you need from your local ASU at your cost, you have to get ahold of the pattern specific to your element and regiment though. Ask around your unit, where did they get theirs? hope that helps.
cheers
