I had the same problem when I called the CFC to tell them about my new 11.5" ER Shaw barrel for my 10/22. The lady on the phone tried to convince me that the rifle would now be restricted, I told her no, a 10/22 can have a shorter barrel if the OAL is 26" or greater, she continued to argue, I told her to check the regulations, 5 minutes later she confirmed I was right, and now my certificate says less than 470mm.

I don't trust these ignorant ####s to do the right thing.
