Unitrade Specialized Catalogue of Canadian Stamps
Additions and Errata to the 2020 Edition

Updated: May 14/2020

Report a mistake to the editor.

Despite what some think, every possible effort is made to keep the number of mistakes down to a minimum. As I have said many, many times ... even the smallest of mistakes (no matter how trivial) is not acceptable. I thank those who have the time to read the catalogue from cover to cover with a magnifying glass looking for even the smallest mistake.

All reported mistakes have been corrected for the next (2021?) edition.

Perf corrections

The following stamps have been showing the incorrect perforation measurement since the 2006 edition! I suspect that all of these mistakes are due to the 'ol "copy/paste" syndrome.
