Thanks for your comments. The note I have also has the double front-plate number 14 as pictured on BWJM's post to the "WER0128495 spotted again!" topic, except that the first number 1 is cut off, so it has 4 14 instead of 14 14.
Also, the serial number font is the same as the picture on copperpetes post to the "Faked 10$ note prefix CXT" topic, except the note I have has a NWS prefix.
It was this font which made me suspicious, then the prefix. I'm not Canadian, but I've been a world paper money collector so I am somewhat familiar with Canadian currency. The rest of this note is a well-done fake, so I also wonder why the forger blew the serial number.
