Since 1970 one or more PSSC members served on Canada Post’s Stamp Advisory Committee denoting an ongoing and constant representation.
The Stamp Advisory Committee (SAC) was established in 1959 to review and recommend topics and themes for Canada's stamp program. Starting in 1969 its 12 members were appointed by Canada Post’s board of directors to a maximum of two three-year terms. Committee members normally come from philately, history and art or design. The following PSSC members are part of this select group of volunteers.
