On July 1, 1867, the British North America Act, also known as the Constitution Act of 1867, came into effect, marking the union of three colonies into the single nation of Canada. Ontario became one of the four original provinces of Canada alongside Quebec, New Brunswick, and Nova Scotia. The act aimed to unify these regions under a federal system of government, establishing Ontario's role as a key province in the development of the new nation.

The 1976 Summer Olympics, officially known as the Games of the XXI Olympiad, were held in Montreal, Quebec. However, the basketball competition was hosted in Toronto, Ontario, which marked an important event for the city. This was the first time that Olympic events were held in Ontario, bringing international attention and visitors to the region.

The 1985 Ontario general election held on May 2, 1985, was a milestone in Ontario's political history. The election resulted in a minority government with the Progressive Conservative Party losing its long-standing hold on provincial power. The Liberal Party, led by David Peterson, formed an accord with the New Democratic Party and assumed control, ending 42 years of Progressive Conservative rule. This transition marked a significant shift in provincial politics and led to changes in policy and governance.

During the last week of June 1995, Ontario experienced a deadly heat wave, with Toronto being significantly affected. Temperatures soared to extreme levels, resulting in the deaths of at least 61 people in the Greater Toronto Area. This event underscored the challenges posed by heat waves and the need for adequate public health responses, including infrastructures like cooling centers. The heat wave highlighted vulnerabilities in urban planning and prompted discussions on climate change and public health preparedness in Ontario.

On May 4, 1998, the Parliament of Canada passed the Nunavut Act, which paved the way for the creation of Nunavut as a separate territory on April 1, 1999. While Ontario itself wasn't directly divided, the legislative process involved territories associated with the larger regional reorganization of Canada's north, affecting political and administrative boundaries that had been established since Ontario's early development.

The Northeast blackout of 2003 was a significant power outage that impacted parts of the northeastern and midwestern United States and Ontario, Canada. On August 14, 2003, a software bug in the alarm system at a control room of FirstEnergy Corporation in Ohio caused a cascade of power failures over the next 24 hours. Over 50 million people were affected by this blackout, including over 10 million in Ontario. This event led to significant discussions on energy policy and grid security.

From June 26 to June 27, 2010, the G20 Summit was held in Toronto, Ontario, where leaders from twenty of the world's major economies gathered to discuss global economic issues. The event was marked by significant security measures, large-scale protests, and controversial policing tactics. The summit aimed to address the aftermath of the global financial crisis, focusing on issues like financial market reform and economic cooperation. The event drew significant attention to Toronto on the world stage and sparked discussion on civil liberties.

On July 8, 2013, Toronto experienced its greatest one-day rainfall since 1954, with over 126 mm of rain. The flood caused widespread power outages, halted transit, and resulted in significant damage to infrastructure and homes. The storm trapped commuters, disrupted businesses, and was a stark reminder of the city's vulnerability to extreme weather events. Damages were extensive, and the cost to the city reached approximately $940 million, making it one of the costliest natural disasters in Ontario's history.

On October 17, 2018, Canada legalized the recreational use of cannabis nationwide, a move that included Ontario and represented a significant shift in drug policy. Ontario set up the Ontario Cannabis Store as a legal outlet for purchasing cannabis, responding to the new regulatory environment. The legalization was touted as a way to regulate the drug, reduce illegal markets, and ensure public safety, though it also required new laws concerning public consumption, while impacting law enforcement practices and local economies.

On March 17, 2020, Ontario declared a state of emergency in response to the growing COVID-19 pandemic. This was part of a series of unprecedented measures to limit the spread of the virus, including the closure of schools, non-essential businesses, and restrictions on gatherings. The emergency declaration granted special powers to the government to implement emergency plans and allocate resources necessary for public health and safety. The state of emergency had profound impacts on Ontario's economy, education system, and health care services.
