I had the time to read through the media press information kit that was distributed at the Bank of Canada launch in Vancouver. In it, there are a total of 35 - full colour pages of the presentation describing the details of the $100 security devices.
They actually use the JPH (experimental/test) note, and to my surprise, they have the Knight / Dodge signatures on each of their pictures. No where on their presentation do they have Jenkins / Knight.
In my opinion, the Bank of Canada conducted tests long before the appointment of Paul Jenkins, and as a result, used the current deputy governor, Malcolm Knight, to produce these test notes.
These Bank of Canada kits have ton of information.
