We are pleased to provide a comprehensive database of Canadian machine slogan cancellations. This database was developed and is being maintained by Cecil Coutts. It contains the data contained in Slogan Postmarks of Canada, published in 2007, as well as much more data that has never before been published. We make it available here as a fully searchable database.

The classification system and numbering system for Canadian slogan cancels is the copyright of Cecil C. Coutts and cannot be used in publications without his express written consent.
