Book excerpt: Many thousands of black people were enslaved in the Maritimes, Quebec, and Upper Canada between the seventeenth and early nineteenth centuries. It is not surprising that slavery played a part in Canadian history, but it is startling that it has not received widespread attention from the general Canadian public or from historians. This sourcebook collects a variety of documents, including runaway-slave advertisements, letters, court cases, and official government documents, offering readers an opportunity to explore black slavery in the Maritimes and revise their understanding of Canadian history.
