Not doing any transfers at the moment - but I've called a half dozen times within the last week and only got through to the main-line for RCMP once and then they transferred me to the ON chief firearms officer and it went straight to auto-recording saying call back later. Office has been playing the same recording every time I've called in the past week. Just trying to change my address for Restricted.
Side note: I've only had to wait more than a week for a restricted transfer Once (for my first pistol years back). ever since then I would call the same day I initiated the transfer and keep it up and within a day or 2 it was approved. Really depends on how soon you want it completed - otherwise don't call and you may get lucky in 10-15 business days.
