> Once the design and substrate were chosen, the Bank of Canada negotiated a contract with Note Printing Australia (NPA) for the supply of the substrate polymer and the security features implemented in the design. The substrate is supplied to NPA by Securency International (now known as Innovia Films Ltd). The Bank also negotiated for the rights to the use of intellectual property associated with the material and security features owned by the Reserve Bank of Australia.
