I don't know if this is widespread, but if you have the card, I'd advise you to go check your statement for unusual charges.
Yesterday, I came home to a letter saying to call RBC Security right away (they tried calling me, but my old cell # was on file).
Turns out someone tried to put a relatively small charge through the card in the US. Their systems flagged it as an unusual spending pattern and declined the charge.
The card is cancelled and a new one is one the way. Kudos to RBS for its robust security system.
Probably a one-off, but just in case....
