Governor General’s Foot Guards envelope, 150th anniversary
Issue date: 7 June

From Canada Post’s Details philatelic catalogue:

The Governor General’s Foot Guards have participated in every engagement undertaken by the Canadian Army since Confederation, served abroad as peacekeepers, and provided emergency assistance to communities at home. Known for their scarlet tunics and tall bearskin caps – seen in ceremonies, on sentries and at regimental band performances – the Guards’ citizen soldiers have served with precision, pageantry and pride for 150 years.
