The Canadian Meter Study Group

In 1981, The Canadian Meter Study Group, CMSG, was formed as part of the Postal History Society of Canada. Clay Rubec was the editor of the Canadian Meter Stamp Newsletter until about 1986. In 1988 Ross Irwin picked up as the newsletter editor, with Dave Cooper as associate editor, and they have continued in those roles since. From his first issue in 1988 Professor Irwin has used the newsletter to develop the CMSG catalog by providing a few pages at a time and those pages are interspersed in the Newsletter issues. This library includes all issues of the CMSG Newsletter and an Index compiled by Irwin. The CMSG Catalog is also assembled separately.

In 2004 Ross Irwin published a revised Canada Meter Postage Stamp Catalog based on the CMSG catalog. Where the CMSG Catalog numbering system (as with earlier Irwin Catalogs) was roughly based on when the meter type first appeared, the 2004 edition is based on manufacturers.

The information included here can also be found at this site. Although the PHSC study group is inactive at this time, more current information is available at the Meter Stamp Society website.

The CMSG Newsletter and Index

The seventy issues of the CMSG Newsletter, issues between 1918 and 2005, are available here. A static index has been compiled. This can be consulted to locate a desired issue. The newsletters themselves can be found in a table on the Archive page. We hope to be able to provide a searchable index sometime in the future.
