The only information is what has been heard through the grape vine. The new Signature was going to show up in the $50, and then the $5. The other denominations release times are still not known as far as I know.
It was originally thought that the new signature was going to be released into circulation early-summer, and that they would have been seen at the CNA in Ottawa.
It is believed that the original release date of the $50 and $5 were both delayed into circulation, thus I would assume that the other denomination would also be delayed.
From the information posted on the forum, and gathered personally, these are the only two known confirmed denominations ($50's & $5's) with the new signature at this time in circulation, and they were found in early autumn.
Just give it time and you will start seeing the other denominations with new signatures. Just keep the forum up to date with your new finds.
