Thanks for the reply! I was afraid that this is case... sigh, another 2-3 months of waiting :-(That application is completely cancelled. Once they get the package with full fees, you'll be back in the queue but will be placed behind others ahead of you. You'll likely have to wait another 2 - 3 months from when your OWP application with full payment is re-received by the Vegreville office.
The correct fee is $255: $100 for the work permit holder, and then $155 for some other fee which the name is escaping me. I too submitted only the $100 fee and had my OWP returned to me in the mail with a letter stating that I have insufficient fees. I have the full timeline in my signature - good luck! Get it in ASAP to minimize any more waiting :[
