Words to know
enslaved person
A person forced to work without pay and treated as property. We say "enslaved person" to remember they were people first.
abolition
Ending something by law, especially slavery.
freedom seeker
A person who escaped slavery to find freedom.
Underground Railroad
A secret network of people and safe places that helped freedom seekers escape from slavery in the United States, many of them to British North America.
extradition
Sending a person back to another country to face charges.
Emancipation Day
August 1, the day the Slavery Abolition Act took effect in 1834. Canada officially recognized it in 2021.
Let's start with a question
What would it take for you to walk hundreds of kilometres, mostly at night, through forests and swamps, not knowing whom you could trust?
Thousands of people did exactly that in the first half of the 1800s. They were escaping slavery in the United States, and many were heading for Upper Canada.
Remember from earlier
In Strand A you learn that slavery existed in New France and in the British colonies, and that Upper Canada's 1793 Act to Limit Slavery stopped new enslaved people from being brought in. Under that law, children born to enslaved mothers were to be freed at age 25. People already enslaved stayed enslaved.
In Lower Canada, court decisions around 1800 made slavery very hard to enforce, and it slowly declined. But in 1800, slavery was still legal across British North America.
The end of slavery in the British Empire
- Enslaved people, free Black communities and anti-slavery campaigners (called abolitionists) worked for decades to end slavery.
- Britain's Slavery Abolition Act received Royal Assent in 1833 and took effect on August 1, 1834. It ended slavery in most British colonies, freeing more than 800,000 people, mostly in the Caribbean and South Africa.
- In British North America, slavery had already become rare. The Act freed fewer than 50 people there.
- The Act paid £20 million to slaveholders in other colonies for their "lost property". The people who had been enslaved received nothing. In many colonies, freed people were also forced to keep working as "apprentices" for several more years.
- August 1 has been celebrated as Emancipation Day since 1834. In 2021, Canada's Parliament officially recognized it.
The Underground Railroad
In the United States, slavery remained legal in the South. Enslaved people escaped north, helped by a secret network that came to be called the Underground Railroad (the name came into use in the 1830s). It was not underground and not a railroad! Its language was secret code:
- Conductors guided freedom seekers. Stations were safe houses. Passengers were the freedom seekers.
- People travelled mostly at night, on foot, by wagon or by boat, and followed the North Star.
- Black people, both free and escaped, did much of the most dangerous work. Some white allies, including many Quakers, helped too.
Many crossed into Upper Canada at places like Amherstburg, Sandwich (Windsor), Niagara and across Lake Erie and Lake Ontario. Historians estimate that 30,000 to 40,000 freedom seekers reached British North America before slavery ended in the US in 1865. The numbers grew sharply after the US passed the Fugitive Slave Act in 1850, which let slave catchers seize freedom seekers anywhere in the northern states. Then, the only truly safe place was British territory.
Josiah Henson reached Upper Canada with his family in 1830. Later, in the 1850s, Harriet Tubman guided freedom seekers to St. Catharines.
The Underground Railroad used railway words as a secret code. Each code word (top) stood for something real (bottom).The Blackburn case, 1833
Thornton and Lucie Blackburn escaped slavery in Kentucky in 1831 and settled in Detroit. In 1833 they were arrested to be sent back into slavery. Detroit's Black community rose up and freed them: Lucie was helped across the river to Upper Canada, and Thornton was freed by a crowd. They reached Amherstburg in Upper Canada.
Michigan asked Upper Canada to extradite (send back) the Blackburns. Upper Canada's Lieutenant Governor John Colborne and Attorney General Robert Simpson Jameson refused. They ruled that sending them back to slavery would be a far harsher punishment than any crime would bring in Upper Canada.
This was significant: it set a precedent (a model for future cases) that protected freedom seekers in British North America from being sent back. Some legal scholars see it as an early root of Canada's way of welcoming refugees.

Reaching British territory meant freedom from slavery, but not freedom from racism. Black people in the colonies often faced:
- being kept out of some jobs and neighbourhoods;
- segregated schools: in 1850, a change to Canada West's school law allowed separate schools for Black children, and some white trustees used it to keep Black children out of common schools, even when Black parents objected;
- the danger of kidnappers who crossed the border to seize people;
- unequal treatment by officials, as with the half-size land grants for Coloured Corps veterans.
Black communities fought back by building their own churches, schools and newspapers, signing petitions and going to court.
Worked exampleModelled example: Why was the Blackburn case significant?
Use the tests of historical significance to judge the Blackburn case.
- Did it affect many people? Yes: not just two people, but every freedom seeker who came after, because it set a precedent.
- Was the impact deep? Yes: it was the difference between freedom and slavery.
- Did it last? Yes: the principle that Canada would not send people back to slavery held, and some scholars link it to Canada's later refugee policies.
- Does it reveal something important? Yes: it shows Black communities acting together (the Detroit uprising) and the law of Upper Canada drawing a line against slavery.
The Blackburn case was highly significant: a decision about one couple protected thousands of freedom seekers.
Words matter
Say enslaved person rather than "slave", and freedom seeker rather than "fugitive" or "runaway". These words remind us that people were people first, and that escaping was an act of courage, not a crime.
Hands-on activityFollow the North Star
You need: a clear night, warm clothes in cold weather, and a grown-up. (No telescope needed.)
- Go outside with a grown-up on a clear night, away from bright lights if you can.
- Find the Big Dipper, seven bright stars shaped like a ladle (a free star-map app can help).
- Find the two stars at the end of the Dipper's "cup". Follow the line they make upward about five times their distance apart. You reach Polaris, the North Star.
- Face Polaris. You are facing north.
- Talk: why was the North Star so important to freedom seekers? What would make it hard to use (clouds, forests, fear)? Some songs sung by enslaved people are said to have carried secret directions, such as "follow the drinking gourd" (the Big Dipper).
If it's cloudy, use a compass or a map app to find north from your front door instead.
Your turn
1When did the Slavery Abolition Act take effect?
2Who received money when slavery was abolished, and who received none?
Slaveholders (in other colonies) shared £20 million. Formerly enslaved people received nothing.
3What were "conductors" and "stations" on the Underground Railroad?
Conductors were guides; stations were safe houses.
4About how many freedom seekers reached British North America before 1865?
5What did Upper Canada decide in the Blackburn case?
It refused to send the Blackburns back to the US, because returning them to slavery would be far harsher than any punishment in Upper Canada.
6Why did the US Fugitive Slave Act of 1850 send more people to British North America?
It let slave catchers seize freedom seekers anywhere in the northern states, so only British territory was truly safe.
7Name two obstacles Black people faced even after reaching freedom in the colonies.
Any two: racism in jobs and housing; segregated schools; kidnappers; unequal treatment by officials.
More practice: warm-up
1What does abolition mean?
Ending something by law, especially slavery.
2When did Josiah Henson reach Upper Canada?
3From which state did the Blackburns escape?
4What star did freedom seekers follow?
The North Star (Polaris).
5What day is Emancipation Day?
More practice: on your own
1Why did the Slavery Abolition Act free so few people in British North America?
Slavery had already become rare there because of laws like the 1793 Act and court decisions in Lower Canada; most enslaved people in the Empire lived on Caribbean plantations.
2Explain why the Underground Railroad was described in railroad words.
Railroads were new and exciting in the 1830s. Using railroad words was a code: talking about "passengers" and "stations" sounded harmless if overheard.
3Why is the Blackburn case called a precedent?
It set a model that later cases followed: freedom seekers would not be sent back to slavery from British North America.
4How did the 1850 change to the school law become an obstacle?
It allowed separate schools for Black children, and some white trustees used it to keep Black children out of common schools, often giving them poorer schooling.
5Who did much of the most dangerous work on the Underground Railroad?
Black people, both free and escaped, including freedom seekers who returned to guide others, like Harriet Tubman.
Challenge
1Explain the difference between being "free" and being "equal" for Black people in Canada West in 1850.
Free: no one could legally own them, and they would not be sent back to slavery. Equal: having the same chances in jobs, schools, housing and treatment. In 1850, Black people were free but not equal: they faced segregated schools, racism and unfair treatment.
2From three perspectives (a freedom seeker, an enslaver in Kentucky, an official in Upper Canada), how might each describe the Blackburns' escape?
Freedom seeker: a brave escape to freedom, and a victory for the community. Enslaver: theft of "property" and a riot that broke the law. Upper Canada official: a legal question; returning them to slavery would be unjust under Upper Canada's laws. Different values lead to completely different descriptions.
3Why do you think the Slavery Abolition Act paid slaveholders but not the people who had been enslaved? What does this tell us about whose interests the government protected?
Slaveholders were powerful and wealthy, and many sat in or influenced Parliament; the law treated enslaved people as property. It shows the government protected the interests of property owners, not the people who had suffered. Today many people call for recognition of this injustice.

For parents and teachersBig idea: Students describe the end of slavery and the Underground Railroad (B3), investigate perspectives (B2), and analyse the lives of Black people in the colonies (B1). This responds to the 2026 curriculum's emphasis on Black individuals' and communities' contributions to Canada and the obstacles they faced.
Talking about slavery: Be honest and calm: slavery was cruel and treated people as property. Avoid graphic descriptions of violence. Emphasize the agency and courage of enslaved and Black people, who led their own escapes and built communities. Also avoid a "Canada the hero" story: slavery existed here too, and freedom did not mean equality.
Safety: Stargazing should be done with an adult, dressed for the weather.
How to help: Mark Emancipation Day (August 1) together. If you're in southern Ontario, look up nearby heritage sites (e.g. Uncle Tom's Cabin Historic Site in Dresden, Buxton National Historic Site, Salem Chapel in St. Catharines, Amherstburg Freedom Museum).
Common difficulties: Believing there was never slavery in Canada; using "slave" and "runaway" uncritically; thinking the Underground Railroad was a real train.
