Answer:
Some fugitives went to Canada instead of staying in northern states because they risked being captured in northern states.
Explanation:
During the time of slavery in the southern United States, escaping slaves had to leave the southern states in order to guarantee (to some extent) their freedom. Even so, many times the owners crossed the Mason-Dixon Line and captured the fugitives, either in open places in front of anyone, or with the collusion of the authorities. Therefore, once the Underground Railroad (the organization that was in charge of helping the slaves to escape) was formed, many routes were directed directly to Canada, so as not to saturate the routes to the great northern cities such as New York, as to guarantee the safety of slaves in a country that had abolished slavery in 1807.
