I think there are people spreading misinformation here.
I have initiated/completed 4 transfers by mail.
In each case I have a reference number and serial number to identify which ref # belongs to which firearm.
I am not expecting any phone calls from either the CFP or CFO.
I would expect that mailed in transfers that were incomplete (such as no signature, or an incorrect registration number) would just get tossed, I would not expect the CFP to call. The CFP don't even call or email to supply a reference number for a good transfer, why would they waste time with people who can't follow simple instructions to complete a form? (which as an aside there seems to be an abundance of on this forum)
I have had discussion with the CFO and the person told me that all that needs to happen now is for the CFO to approve.
So that may take some time, but I'm not expecting any calls.
BUT I Have been to my MPP's office to discuss the slow service in person. Some more people on here should do that
No false information, I posted my actual experience of transfer initiated by email from Yukon to Ontario
