Can't find chipotle powder either eh? I found it once... Damned if I can remember where.
Cayenne Pepper is normally called for as a substitute for chipotle. If you want to add-back the smoke flavour you could add a drop of liquid smoke (or put it on your smoker). I'm convinced this is what most restaurants do for the "chipotle" dishes do up north anyways.
Also could use Jalapeno flakes, but these are just as hard to come by in Ontario.
