The Bank of Canada announced it would be removing the legal tender status of five old Canadian bills.
The move is meant to keep in circulation the bills with security features that are more difficult to counterfeit.
The affected bank notes are the bills for the 1, 2, 25, 500 and 1,000 denominations, many of which were printed only for a limited time.
If you still have these bills in your possession, they’ll be worthless in stores, but you can turn them in to your bank. Some collectors would also probably pay for the more rare notes. The $500 bill, for example, was printed in 1935 to commemorate the ascension of King George to the throne. Only 40 such bills exist.
