The OP might be referring to a statute that permits a trial in absentia (and extradition) when a citizen commits a crime while abroad. The USA has a similar statute on the books - for example, a US citizen who is caught attempting to have sex with a minor while abroad can be tried and convicted of a crime, even though no crime occured on US soil.

I doubt very much that Canada has the time, interest or ability to gather evidence to try and convict me or anyone else for wrecking an RFID tag in a passport or trying to wreck havoc on the data they store on us.
