was issued in 1956. 1969 Scenes of Canada Because of a growing concern over counterfeiting, the Bank of Canada began to release a new series of bank notes in 1969. This series represented another complete departure in design from earlier issues: colourful, wavy patterns were introduced; a new series of Canadian scenic vignettes was created; portraits of former Canadian prime ministers were re-introduced. Both Laurier and Macdonald were on the 1935 and 1937 series, but now joined by King and Borden. This was the last series to feature a $1 banknote, with the banknote replaced by a dollar coinknown as a loonie for its design of a loon on the obversein 1987; printing of the $1 banknote ceased in 1989. However, there was a 21-month period where both the $1 bill and coin were produced concurrently, from June 1987 to April 1989. 1986 Birds of Canada In 1986 the Bank of Canada introduced new banknotes called the Birds of Canada series. The design on the back of each note features a bird indigenous to Canada with a background representing the typical landscape for that bird. The portraits on the front of the note were made larger than those of previous series, and a metallic patch was introduced on the larger notes. Each banknote weighs . This series was the first to include a bar code with the serial number. This allows the visually impaired to distinguish notes with the use of a hand-held device that tells the note's denomination. This was also the last series that the $2 and $1,000 notes were issued. The $2 note was withdrawn in 1996 and replaced by the $2 coin, known as the toonie. The $1,000 note was withdrawn by the Bank of Canada on 12 May 2000, at the request of the Royal Canadian Mounted Police (RCMP) as part of a program to reduce organized crime. At the time, 2,827,702 of the $1,000 bills were in circulation; by 2011, fewer than 1 million were in circulation, most held by organized crime. 2001 Canadian Journey Beginning in 2001, the Bank of Canada introduced a new series of notes called "Canadian Journey", featuring images of Canadian heritage and excerpts from Canadian literature. The $10 was first issued on 17 January 2001; the $5 on 27 March 2002; the $100 note on 17 March 2004, the $20 on 29 September 2004, and the $50 on 17
