The Constitution Act, 1867 (then called the British North America Act) set up Canada’s new federal system and defined the roles of the federal Parliament and the provincial legislatures. It created the offices and structures needed to run the country, including a federal Cabinet responsible for government decisions and a Parliament with the Senate and House of Commons.
On the day Confederation began, John A. Macdonald formed the first federal ministry (Cabinet). This mattered because the Cabinet and prime minister became the main decision-makers for day-to-day national government, coordinating federal departments and policy across the new Dominion.
Ontario established its first provincial Cabinet shortly after Confederation, led by John Sandfield Macdonald. This helped put the new division of powers into practice, with provinces now responsible for key areas such as local institutions and many social services under the new federal system.
Canada’s first federal election selected members of the House of Commons for the new Parliament. The election was held over several weeks, reflecting the reality that voting rules and timing still differed by province in the early Confederation period.
The first session of Canada’s Parliament opened in Ottawa, beginning the regular work of federal lawmaking and oversight. This step turned Confederation’s constitutional design into an operating government, with debates, budgets, and legislation now handled through the new federal institutions.
The Manitoba Act created Manitoba as a new province and set up its basic governmental framework. It was an early test of how Confederation would work as Canada expanded, because it required new provincial institutions and a new relationship with the federal government.
An Order in Council admitted Rupert’s Land and the North-Western Territory into Canada’s union. This expanded Canada’s responsibilities far beyond the original four provinces and increased the need for new federal administrative and policing institutions in the West.
The transfer of Rupert’s Land and the North-Western Territory took effect, and the lands were organized under the name North-West Territories. This change expanded federal administration and pushed the Dominion to develop practical ways to govern and provide order across large, sparsely populated regions.
British Columbia joined Canada as a province, extending Confederation to the Pacific coast. Its entry strengthened the case for national institutions that could manage a larger country, including finance, transportation commitments, and representation in Parliament.
Parliament passed legislation to create the North-West Mounted Police (NWMP), responding to the need for law enforcement in the newly acquired western territories. This was a major federal institution-building step because it provided a national tool to enforce laws and support the expansion of Canadian administration in the West.
Prince Edward Island entered Confederation and became a province of Canada. Its addition showed Confederation was not a one-time event in 1867 but an ongoing process, requiring Canada’s federal and provincial institutions to adapt to new members and new policy commitments.
Parliament created the Supreme Court of Canada, establishing a national court to hear appeals and interpret federal law. This strengthened Confederation’s legal framework by adding a central judicial institution to help resolve disputes and provide more consistent legal decisions across provinces.
