I just had one last night and have the wrapper! They are made by Cavlier. They have a website http://www.cavalier.be/index.htm
but it's in Belgium. There is info for a distributor in Nova Scotia on the label:
Assorted Confectionery Trading Ltd
Nova Scotia B3B 1K8
phone 902 468 5865
fax 902 458 1827
email act.confectionery~ns.sympatico.ca

Cavalier makes quite a few different sugar free chocolates.
