In short
On July 1, 1879, Canada officially established Dominion Day to mark the anniversary of Confederation in 1867, when the British North America Act united four colonies into a single federal dominion. The holiday celebrated Canada's new status as a self-governing entity within the British Empire-a model that would later be formalized as the foundation for the modern Commonwealth.
How it unfolded.
The five-minute version
What actually happened.
Dominion Day was a day commemorating the granting of certain countries Dominion status - that is, "autonomous Communities within the British Empire, equal in status, in no way subordinate one to another in any aspect of their domestic or external affairs, though united by a common allegiance to the Crown, and freely associated as members of the British Commonwealth of Nations". It was an official public holiday in Canada from 1879 to 1982, where it was celebrated on 1 July; that date is now known as Canada Day. In the Dominion of New Zealand, the anniversary of the granting of Dominion status, on 26 September, was observed as Dominion Day; it was never a public holiday.

The world it landed in
What was on the radio, the screen, and everyone's mind.
Same week, elsewhere
In 1879, Canada was consolidating its identity post-Confederation (1867). The establishment of Dominion Day reflected the nation's desire to mark itself as a distinct political entity within the British Empire, separate from provincial commemorations. This period saw nation-building through infrastructure (the Canadian Pacific Railway began construction in 1881) and westward expansion, with Dominion Day serving as an official anchor for national consciousness during a formative period of Canadian state development.
