Squared Circle Postmarks of Canada
October 2022 update to the 6th edition published in January 2020
Prepared by the BNAPS Squared Circle Study Group. Edited by Rick Friesen.
The October 2022 update replaces all the sections of the 6th edition of the Handbook. The Handbook is organized according to hammer type and province. In over 680 pages, it provides an exhaustive treatment of each hammer: period of use, time marks, indicia information, stamp issues on which the hammer is found, rarity factors, and illustrations of hammer usage. Section 1 of the Handbook provides an introduction to these fascinating postmarks.
Rick Friesen has compiled two censuses of Squared Circle postmarks plus a census of Barred Circle postmarks, all on the Map Stamp:

Barred Circle Postmarks of Canada on the 1898 Canadian 2¢ Imperial Penny
Postage Issue (The ‘Map Stamp’):
A Cover Census (1.8 MB)
Rick Friesen
This is a census of Map Stamp covers with Barred Circle postmarks, often referred to as precursors of Squared Circle postmarks. The hammers, introduced in 1892, were issued to nine towns in Canada (Halifax, Hamilton, London, Montreal, Ottawa, St. John, Seaforth, Toronto, and Winnipeg) and St. John’s, Newfoundland. The census currently documents 72 covers with Montreal strikes and one with a St. John’s, Newfoundland, strike.
