Hi Az100, by certified by a JP, I mean I got the letter notorized by a justice of the peace/notary public. I felt more comfortable doing that because it was a family member and I felt more confident that my letter was authenticated by someone in authority. That was not a requirement by CIC, I just felt more comfortable within myself to do it that way. However, remember that to use experience as a qualification for LIC, you have to have a minimum of two years, paid, full time employment. The best of luck on your application ok.
