William Hamilton Merritt played a role in making St. Catharines a centre of abolitionist activity. In 1855, the British Methodist Episcopal Church, Salem Chapel was established at the corner of Geneva and North streets, on land granted to the congregation by Merritt in the early 1840s. The area became known to refugee slaves from the United States as a place of "refuge and rest"; it was a destination, one of the final stops in Canada on the Underground Railroad for refugee African-American slaves. During this time, abolitionist Harriet Tubman lived in St. Catharines. By the mid-1850s, the town's population was about six thousand, 800 of whom were of African descent. St. Catharines remains an important place in Black Canadian history.
