Can’t really answer the OP question, but I’ve got a similar story as SkipperClyde to tell.
Last fall we traveled from Alaska to Newfoundland and re-entered Canada at Calais, ME / St. Stephen, NB. Our interview went in part as follows:
Canadian Border Guard: Do you have any guns?
Us: No.
CBG: No handguns?
Us: No.
CBG: No rifles?
Us: No.
CBG (a little more incredulous): No shotguns?
Us: No.
CBG (voice rising in pitch): Any at home?!
Us: No.
CBG (sounding exasperated): You’re from Alaska and you don’t have any guns?!?!
Us: No, but we have bear spray!
