This sub-series documents the Canadian Textile and Chemical Union (CTCU), which grew out of the Canadian Textile Council (CTC) founded by Madeleine Parent and Kent Rowley in 1952. The CTCU represented manufacturing and service workers and became affiliated with the Canadian Association of Industrial, Mechanical and Allied Workers (CAIMAW). In 1992 the CTCU merged with the Canadian Auto Workers (CAW) to become Local 40. However, there are no documents related to the merger in this sub-series. The CTCU was also a member of the national trade union center, founded by Parent and Rowley, the Confederation of Canadian Unions (CCU).
The sub-series consists of the CTCU's annual conventions, constitution and by-laws, and files relating to specific union disputes and agreements. There are related materials on the CTCU's union activities in the Artistic Woodwork Company Limited sub-series (C9) and the Puretex Knitting Limited sub-series (C10).

This subseries consists of assorted documents pertaining to the life and work of Roy States. When the Roy States collection was donated to Rare Books and Special Collections, many of the ephemeral materials were initially placed into individual envelopes or folders, were given individual identification codes, and were listed in the printed finding aid for the collection. In a later processing stage, the envelopes whose contents related most directly to States were assembled into a group and housed in a dedicated box. These reboxed materials now form subseries 02 of Series A. A particularly important biographical item in the subseries is the "Resumé of experience and activity" binder which States complied.
