When did the British Parliament abolish slavery throughout the Empire?

Discover Canada records this final abolition step in one direct sentence. The guide writes: In 1807, the British Parliament prohibited the buying and selling of slaves, and in 1833 abolished slavery throughout the Empire. Two dates, two distinct measures: 1807 for the slave-trade ban, and 1833 for full abolition. The answer the test wants is the second of these — 1833.

The guide places this inside a longer abolitionist story that begins much earlier and is partly Canadian. Discover Canada notes that "the first movement to abolish the transatlantic slave trade emerged in the British Parliament in the late 1700s," and credits a province of British North America with the first concrete step: In 1793, Upper Canada, led by Lieutenant Governor John Graves Simcoe, a Loyalist military officer, became the first province in the Empire to move toward abolition. So Canada's contribution sits at the start of the timeline; the Empire-wide abolition in 1833 sits at the end.

Discover Canada connects the post-1833 picture to a Canadian theme too. After British abolition, the guide says, "thousands of slaves escaped from the United States, followed 'the North Star' and settled in Canada via the Underground Railroad, a Christian anti-slavery network." So even after the British Empire was free of slavery in 1833, Canada continued to receive enslaved people fleeing from the still-slaveholding United States — until the U.S. fought its own civil war over the same question in the 1860s.

The 1833 date is one of the few precise legislative dates Discover Canada attaches to an Empire-wide moral reform. New citizens are expected to know that British abolition came in two steps — the trade ban in 1807 and full abolition in 1833 — and to be able to pick the right step from the list of distractor years.

The date also has a Canadian framing the test rewards. Discover Canada emphasises that Upper Canada under Lieutenant Governor John Graves Simcoe moved toward abolition first, in 1793. So the 1833 figure should be remembered alongside the 1793 figure, with the British Parliament catching up to a Canadian lead 40 years later.
