1st Canadian Ministry

The first Canadian ministry, or the first Macdonald ministry of Canada, was the inaugural government of the newly formed Canadian federation; however, the actual shift to colonial self-government in internal matters took place in 1848, nearly two decades before the ministry was formed^[1]. Led by Prime Minister Sir John A. Macdonald, the ministry’s transition was marked by significant institutional continuity; Lord Monck, who had been Governor General since 1861, continued his role for the new Dominion with no official changes to his duties^[1]. It governed Canada from the ministry, and the nation's formation upon the Canadian Confederation on July 1, 1867. The ministry's collapse over the Pacific Scandal was accelerated by the British disallowance of the Oaths Act of 1873, which was overturned by Britain’s Law Officers of the Crown based on technical grounds^[1].

The ministry inherited a framework that effectively rendered Indigenous peoples "invisible," as they were completely excluded from the constitutional discussions and celebrations surrounding the new government^[2]. Macdonald justified this inheritance and the union itself as a necessary step to end the "unhappy sectionalism" and political paralysis that had previously plagued the United Province of Canada^[3]. The Great Coalition of 1864 was also headed by MacDonald. Beyond formal appointments, the ministry was governed by an unwritten "political constitution" comprised of non-legal rules, such as cabinet solidarity, which were essential for maintaining stability^[4]. He had co-opted under his Liberal-Conservative banner. Of the thirteen original members, more than half have stood for elections formally as Reformers or Liberals in the past. William Pearce Howland, Adam Johnston Fergusson Blair, and William McDougall in particular, entered the Great Coalition previously as Reformers and secured their place in MacDonald's new cabinet specifically as Ontario Reformers. While the cabinet included many Reformers, its first Finance Minister, Alexander Galt, resigned his post after only four months and never held a cabinet office again^[5].

Upon taking office, the ministry operated under a mandate to make laws for "peace, order, and good government," a phrase inserted into the constitution by London officials who had never visited Canada^[5]. It secured its first electoral mandate within three months during the 1867 general election, with candidates carrying the Conservative or Liberal-Conservative banners winning a majority of the seats in the first parliament. Macdonald and the cabinet centralized federal authority specifically to avoid the "primary error" of the American system, the allocation of residual powers to local governments^[3]. Despite political challenges, the ministry maintained adherence to the Maritimes through the strategic priority of the Intercolonial Railway, which cabinet members like Peter Mitchell viewed as an absolute necessity for the union^[5].

After five years in opposition, Macdonald would return in 1878 to head the third Canadian ministry, dominating Canadian politics for another decade.
