* The King-Byng Affair: The most notable event was the King-Byng Affair, which involved a constitutional crisis. King, the leader of the Liberal Party, had been defeated in the 1925 election but refused to resign as Prime Minister. He sought to dissolve Parliament and hold a new election, but the Governor General, Lord Byng, refused, acting on the advice of the Conservative leader, Arthur Meighen. This sparked a major debate about the roles of the Governor General and the Prime Minister, and ultimately led to a new election in which the Liberals were victorious.
* The 1926 Federal Election: Following the King-Byng Affair, a new election was held in 1926. This election was seen as a referendum on the constitutional crisis, with the Liberals ultimately winning a decisive victory, allowing King to return to power as Prime Minister.
* The "Nationalist" Government: Following the election, King formed a "nationalist" government, which included representatives from various parties. This was seen as a way to unify the country and promote national unity.
These events had a profound impact on Canadian politics and constitutionalism, solidifying the power of the Prime Minister and setting precedents for future interactions between the Governor General and the government.
