Canadian Postmasters and Assistants Association
Canadian trade union
The Canadian Postmasters and Assistants Association (CPAA; French: Association canadienne des maîtres de poste et adjoints [ACMPA]) represents rural postal workers for the Canada Post Corporation. The trade union belongs to the Canadian Labour Congress as the federation's smallest national union.
The organization publishes The Canadian Postmaster and hosts a triennial convention.
History
The organization began in 1902 in Stonewall, Manitoba. From there, the trade union spread out through rural areas of Canada. In 2002, Canada issued a commemorative stamp for the organization's 100th anniversary.
In recent years, the organization has struggled with closures of rural post offices designed to cut costs at Canada Post. Even among rural post offices that remain open, many face cuts in hours and staff.
Jurisdiction
The union represents Canada Post employees who work in rural post offices. There are approximately 6,462 full- and part-time permanent staff who are members of CPAA. In addition, there are approximately 5,209 term or temporary employees.

The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
