On today’s date in 2017, Canada Post continued its celebration of Canada’s sesquicentennial with the unveiling of another stamp from its Canada 150 program.
This stamp – the second of 10 Canada 150 stamps released before June 2017 – commemorates one of the most iconic moments in recent Canadian history, the proclamation of the Constitution Act on April 17, 1982.
The proclamation by Queen Elizabeth II signified a symbolic step in Canada’s independence as a nation. While giving Canada full control over future constitutional amendments, the act also embodies the Charter of Rights and Freedoms, which guarantees essential rights and freedoms for citizens and others who live in Canada.
Unveiled on Parliament Hill, the stamp’s design depicts a section of the cover of the printed act. The issue was designed by Roy White and Liz Wurzinger, of Subplot Design in Vancouver, B.C., and printed by the Lowe-Martin Group.
A total of 80,000 panes of 10 stamps; 400,000 booklets of 10 stamps; and 100,000 official first-day covers were produced.

The official first-day cover features a section of the cover of the printed Act, which was signed by Queen Elizabeth II on April 17, 1982.
