I am the editor of the Unitrade Specialized Catalogue of Canadian Stamps. The 2022 edition was sent to the printer in May 2022 and began shipping around October 21, 2022.

I do not sell the catalogue. Please contact the publisher (Unitrade Associates) directly or your favourite stamp dealer.


  Here are some highlights:

  • continue to add more images of specific varieties (when made available to us)
  • continue to have consistency throughout the listings (this will continue with future editions) and correct the annoying typographical errors (some of which have been around for many years!). We cannot guarantee that we have found all of them ... but we will correct any that are reported to us.
  • added a listing of known Picture Postage(tm) items produced by Canada Post for their official mailings including invitations to their events (page 672)
  • illustrated all of the annual collections (page 684)

  • price: CAN$74.95

16 more pages were added to the catalogue (it is now 792 pages).
