Well, it's probably too late, but I've been hearing about his from several sources.
Turns out that the Canadian government has contracted out the processing of the 2006 census to US missile/bomb/arms/aircraft manufacturer Lockheed Martin. Not only that, but (like BC Medicare) all the information is accessible to the US government under their Patriot Act.
Check out http://census.vivelecanada.ca/... or just google "Canadian 2006 census boycott" or such words. So boycott the damn thing to let Stats Can know that we don't want our information going to the US government via one of the world's largest arms manufacturers.
