The CBC, via Yahoo! News, is reporting that a computer containing personal health information on Saskatchewan residents has been stolen from the Toronto office of a contractor. The information apparently was "heavily encrypted" and didn't contain any names or other identifying information, other than "health registration numbers". The article is unclear whether this is a medicare number or some other number.
The contractor apparently had access to this information as part of a project involving the analysis of long-term patient care in Saskatchewan. The Privacy Commissioner for the province has been consulted, but there's no mention of the reaction.
