Eli,
Calcium hydoxide is NOT banned in Canada.  I'm curious as to how having a business license will help getting this in cheaper?
Anyways, up here in Edmonton I'm probably going to be ordering some pickling in.  The cost will probably be $5-$6 per pound (last time was $6/pound), although it will depend on how much is ordered.  In any case, if anyone needs some they can email me at 
dvleemin@jpvleemingpc.com.
