The Bank of Canada introduced a new $100 bill recently – and it has a window in it.

It’s Canada’s first “polymer” (a type of flexible plastic) bill.

The new $100 bill features a picture of Sir Robert Borden, who was the Prime Minister from 1911 and 1920. The back of the bill celebrates innovation in medical research, including the Canadian discovery of insulin, which is used to treat diabetes.

The new “bank notes” (or bills) are better for the environment than paper bills because they will last more than twice as long. They are also more secure, meaning that they cannot be easily copied or “counterfeited” by criminals.

The $100 bill has a few interesting security features. For instance, there is a transparent window in the bill. The window has a holograph in it which can be seen from either side.

The new $100 bills are able to be recycled, after their lifespan as ended, into other products.

The Bank of Canada is also introducing a new $50 bill in March 2012. A new $20 bill will begin circulating in late 2012, followed by $10 and $5 notes in 2013.
