Do the course and save yourself some possible future hassle.I challenged the non res and passed no probs.Was issued my PAL and all was fine and dandy.Then i decided to get into the pistol game and went and challenged the RES test,once again passed with no problems...waited...waited...waited..got a phone call 1 day from the CFC stating that since i did not take the Canadian firearms safety course that they were unable to approve my RPAL..AND that if i did not take the course in a reasonable amount of time i would have my PAL revoked.To be fair ive spoken to a number of people about this and none of them have ever heard of the CFC doing this before,but they did it to me.So i went and did the course and now everything should be fine.But if i were you i would just do the course.Its they're game and they can and will change the rules whenever they feel like it.
