Well, when I needed to bring in proof of range membership to the Alberta CFO to get a transfer approved I just went to their office, rather than mailing it in and waiting probably 2 days for the letter to make it across the city, then however long it takes them to get around to processing it.
I walked in the office at about 4:21pm, was back out with temp cert in hand by 4:40. So, it might be faster for you as well.
