Where was the Royal Insurance Co. Ld. perforator located?
According to the Canadian Stamps with Perforated Initials handbook, the Royal Insurance Co. Ld. of Montreal, PQ received Post Office permission to operate a perforator on 1912/06/22.
Going through my collection of this pattern looking for town cancels, I found the following pattern of usage:
