I sent a photo copy of my FAC (which I had to have the firearms test in order to get, and I think I had to send the original certificate with it) with my PAL application.

Be sure to go over your application and be sure everything is filled in correctly. I missed checking a little tiny box (about the size of Allen Rocks brain) that indicated I had no previous spouse or common-law partner. They sent me a special form and a photo copy of my original appl. to fill out. I did so and mailed it to them befroe the ink was dry. Then I got a phone call telling me I had not sent them enough money.
