So I've found 2 places that have it!
First, Art napps did have it in stump removal form. (Though she said they weren't getting anymore, perhaps it was just old inventory)
Second, A specific Pharma-save has it (only one pharma-save in BC carries it) (saltpeter).
Of course the issue it that they are charging and arm and a leg. For 2lbs of stump remover it's $16, for 500g of saltpeter it's $17 and for 2kg of saltpeter it's $30
I'm assuming that pharmaceutical saltpeter is probably better then the stump remover (which had no ingredients list, Falling leaf stump remover).
Perhaps I'll get the 2kg package, and maybe see if I can sell small doses to fellow Canadians (and recoup the $30!)
If anyone is wondering.
Canadian Tire no longer carries it (Canada wide)
Safeway/superstore/london drugs/shoppers drugmart/ zellers Pharmacies don't carry saltpeter anymore.
Home depot/Rona don't carry stump remover anymore. (A lady at Rona called me stupid for trying to buy explosives before I even told her what I was using it for)
Homeopathic/organic grocers in the Surrey area don't carry it either.
Thanks for the great Tips, I would have never been able to find the stuff without your suggestions.
