Queenston is a compact rural community and unincorporated place 5 kilometres (3.1 mi) north of Niagara Falls in the Town of Niagara-on-the-Lake, Ontario, Canada.

In 1793, a young black woman named Chloe Cooley was sold as a slave and forced across the Niagara River into the United States, an event witnessed by several Queenston locals.

Despite charges against Cooley's owner being dropped, the public outrage surrounding the event led Lieutenant-Governor Simcoe to push for legislation prohibiting the importation of slaves, resulting in the gradual abolition of slavery in Upper Canada.

Today, Cooley's legacy is commemorated with markers and recognition, including her designation as a National Historic Person, illustrating Queenston's role in this pivotal moment in Canada's history.

Major-General Sir Isaac Brock arrived from Fort George, Ontario with a small force and was killed while trying to regain the heights.

The British, Mohawk and militia troops under Major-General Roger Hale Sheaffe, with reinforcements from Chippawa, Ontario were able to take the hill and captured nearly 1000 prisoners.

Toronto buildings that benefitted from the supply of stone included Queen's Park, the Royal Ontario Museum, Union Station and the Gibraltar Point Lighthouse.
