In 1793, the parliament of the province of Upper Canada (now Ontario) passed An Act to prevent the further introduction of Slaves and to limit the term of contracts for Servitude within this Province.
This Act ensured that the children of slaves, at age 25, would automatically be set free. The Act remained in force until 1833 when the British Parliament's Emancipation Act abolished slavery in all parts of the Empire, including Ontario.
After the War of 1812, the black community in Ontario grew with the steady arrival of runaway slaves from the southern United States. Over the next few years many slaves found freedom by following the Underground Railroad to Ontario.
