Harriet Tubman felt compelled to escort the escaped slaves all the way to St. Catherines in Canada due to the United States' Fugitive Slave Law of 1850, which required northern states to return fugitive slaves back to their owners.

Canada has previously outlawed slavery, which made them a safer destination than any northern state, and St. Catherines had a welcoming community that opposed slavery.
