The bilingual Issue. With the death of King George V and the abdication of his son King Edward VIII in the wake, the young Canadian monetary institution is caught off guard. Only two years after the first issue, it is already necessary to launch the manufacture of a new series of banknotes with the effigy of the new King George VI. The Bank of Canada is taking the opportunity to make significant changes. To make it quick, it is decided to take the ticket of 50 Dollars Type 1935, on which there is already a portrait of the "future" king. This welcome portrait is directly assigned to the first six values of 1, 2, 5, 10, 20 and 50 dollars. In addition, new government legislation requires the mandatory issuance of bilingual banknotes. The bank can therefore stop the expensive manufacture of separate French and English banknotes. In the new graphic composition, the portrait of George VI is judiciously placed in the center and makes it possible to position the texts in English on the left part and the texts in French on the right part. Efforts are also made to typography, colorimetry and graphics, thus contributing to more visual homogeneity between the notes. Thumbnails of the 1935 series reverses are also reused and reassigned to other values. Finally, for the first time, the notes are provided with a real serial number represented by a prefix of two letters superimposed in front of the seven digits of the number, the upper character designating the series, while the lower character indicates the letter of denomination. The control letters then become useless and disappear permanently. On the large values of $ 100 and $ 1000, the Bank of Canada keeps the unchanged portraits of Laurier and Macdonald.
