Re: tag shifts
As noted on page 27 of the Unitrade catalogue, "...we do not list perforation, colour, or tagging shifts in this catalogue."
Also noted, on page 30, "The Editor maintains an extensive website of Canadian philatelic information:
www.adminware.ca . Included on this site is an up-to-date, searchable tagging database of all reported tagging errors. In addition, an errata to this catalogue is also available (something we wish did not have to exist!)."
For those who have not bookmarked these links, here are direct links:
