The Frontiers Issue. A great upheaval occurs with the issuance of this new series. The classic cotton paper used for almost 150 years is replaced by a new support called "polypropylene", made of paper and liquid polymer, thus allowing the new banknotes a greater resistance to the traffic conditions and thus a more durable in the time. Canada is one of many countries to have definitely chosen this manufacturing technique. The transparency of the material offers new technical, aesthetic and safety possibilities that surpass all previous series. The theme of this issue focuses particularly on the country's innovation, technology or human engagement, but keeping the usual portraits related to Canada's historical identity.
