When Britain took over New France in 1763, things did not change for Black slaves. They continued to belong to their owners. The first British governor, General Murray, was himself a slave owner.
By this time, Nova Scotia had been run by the British for 50 years. Settlers from New England had moved there when the British took over and may have brought slaves with them. Slaves helped to build Halifax. In 1767, there were more than 100 Black slaves living in Nova Scotia. By 1776, there were around 500.
