There’s an image on the Citizenship and Immigration Canada website:

An amendment to the Citizenship Act went into effect today.  I took the quiz that the image links to, even though I knew how it would turn out:

1. Have you ever renounced your Canadian citizenship?  
   Nope.
2. Was your Canadian citizenship ever revoked for fraud?  
   No.
3. Where were you born?
   The Inverness hospital–oh, “in Canada.”
4. When were you born?
   (In my case, the right answer is:
   “Between January 1st, 1947, and February 14, 1977.”)
5. At the time of your birth, were your parents foreign diplomats in Canada?  
   No (unless under really deep cover).

So I passed.

Under the new law, “Citizenship will be automatic and retroactive to the day the person was born or lost citizenship, depending on the situation.”  So I’ve zipped back to 1958 when my parents became naturalized U.S. citizens.  At the time, I gained U.S. citizenship through them and automatically lost my Canadian citizenship.

Oh, there it is.  And retroactive, too, so I’ve been Canadian all along.  (You had doubts?) 

I read once that Stephen Hawking claimed time travel would never be possible.  He offered as proof the fact that we haven’t been invaded by tourists from the future.  (I used to think, well,  maybe we’re just the time-travel equivalent of someplace no one wants to visit. )  I guess Canada and I have showed him.
