Abolition of slavery in Upper Canada

The abolition of slavery in Upper Canada (present-day Ontario) was achieved through progressive legal reforms, culminating in the Act Against Slavery in 1834, which aligned with the British Empire’s broader efforts to end slavery. This law prohibited the importation of slaves and gradually emancipated existing enslaved people, with those over 25 gaining their freedom immediately and others earning their freedom over time. These changes reflected increasing social and political momentum toward human rights and set a foundation for further abolition across Canada.
