Mine expires in june, I called beginning of march and asked to have the renewal form sent- received about a week after the call. I filled it out with a new pic from my digital camera and received my new license back today within 3 weeks- not bad for the CFC!!
I also sent in the form from cssa with regards to my information and disclosure of records to the CFC/RCMP, that too was sent--its about one and a half inches thick of firearms registered/transfers/STATT/LTATT -worth getting for your piece of mind I think.
