Re: Surely someone must know where Canadian money is printed? Hi, thanks for the reply. From what I've gathered the BoC distributes notes, but they don't make them. I seem to recall the 2012 thing was in reference to not making paper money, and the shift to plastic/polymer notes.
Money Matters: 2012 Note: 2012 brings big changes in Canadian currency, both bills & coins. Canada is in the process of issuing new polymer (plastic) bills. The 50's & 100's have been in circulation since early 2012, and the 20's will be released in November 2012, with the others to follow.he Canadian Dollar is available in $5, $10, $20, $50, $100. ($1 and $2 bills have been replaced by coins) The notes are coloured and are difficult to counterfeit. (I have never understood the reluctance in the US to move towards different coloured bills.
