I had no trouble flying into the U.S. with my driver's licence and Canadian citizenship card but...

when I returned to Canada, the gal at the airport was on the computer and asked me when the card expired.

Never, I said.

Well, she needed to enter an expiration date in order to access the next page of the I.D. documentation process. She had to call a supervisor who knew how to bypass the expiration date and they let me through.

Everyone acted like it was normal.

Whoever heard of an expiration date on a citizenship card?

Expect the unexpected.
