The Bank of Canada has been issuing bank notes since 1935 and periodically upgrades your notes by releasing a new series. These upgrades are made to stay ahead of counterfeiting and to improve the security of notes in circulation. The Bank is also responsible for ensuring that Canadians have access to bank notes that they can use with confidence.
The Bank has issued seven different series of bank notes and two commemorative bills. They feature the portraits of former Canadian prime ministers and members of the royal family on the front, and scenes that reflect Canadian culture, history, and achievements on the back.
