Criminals can quit now; Canadian $100 bills are now even harder to forge. In Toronto yesterday, the Bank of Canada officially unveiled our new $100 bills and announced them as available countrywide. Made of plastic polymer, these latest banknotes have new security features including transparent windows and text, metallic details, and raised ink.

The new material is also far sturdier, and a nice little extra for the rest of us is that we get to enjoy a visually-refreshing redesign. The front side of each note features its original political figure, but the flip sides now feature commemorations of Canadian contributions to science and technology. CBC has the details. Look for the new 100s to be followed in the coming months by the 50s, 20s, 10s and 5s.
