I can never understand where these minimal numbers come from.    Don Chapman's book The Lost Canadians outlines the story of the thousands of Canadians who had citizenship stripped in recent years.   Some groups have had theirs restored over the years (i,e, War Brides) but many are still without and we still hear of people just learning theirs is gone, usually when they go to apply for a passport or other service.
As Senators McCoy and Omidvar pointed out,   you have more rights when you are faced with a parking ticket!
