In 1793, the administration of Lieutenant Governor John Graves Simcoe passed the Act Against Slavery in Upper Canada that allowed for gradual abolition: slaves already in the province would remain enslaved until death, no new slaves could be brought into Upper Canada, and children born to female slaves would be freed at age 25. This ensured the eventual end of slavery in Upper Canada, although as it diminished the sale value of slaves within the province it also resulted in slaves being sold to the United States. Some slaves in Upper Canada also ran away south to the free states, thus gaining their liberty. By 1797, courts began to rule in favour of slaves who complained of poor treatment from their owners. These developments were resisted in Lower Canada until 1803, when Chief Justice William Osgoode ruled that slavery was not compatible with British law. This historic judgement, while it did not abolish slavery, set free 300 slaves and resulted in the rapid decline of the practise of slavery. However, slavery remained in Upper and Lower Canada until 1834 when the British Parliament's Slavery Abolition Act finally abolished slavery in all parts of the British Empire.
