Upper Canada and Lower Canada are now known as Ontario and Quebec respectively.

Discover Canada records this in one direct sentence about the Constitutional Act. The guide writes: The Constitutional Act of 1791 divided the Province of Quebec into Upper Canada (later Ontario), which was mainly Loyalist, Protestant and English-speaking, and Lower Canada (later Quebec), heavily Catholic and French-speaking. The status the test wants is therefore true — Upper Canada later became Ontario, and Lower Canada later became Quebec.

Two precise commitments. Discover Canada commits the named name change to TWO specific facts: (1) Upper Canada (later Ontario); (2) Lower Canada (later Quebec). So the source pinpoints the named historical-to-modern naming for both colonies.

The named cultural profiles also differed. Discover Canada commits Upper and Lower Canada to specific named cultural profiles: "Upper Canada (later Ontario), which was mainly Loyalist, Protestant and English-speaking, and Lower Canada (later Quebec), heavily Catholic and French-speaking." So the named division was not just geographic — it reflected named religious, linguistic, and political differences between the two new colonies. Upper Canada was characterised as mainly Loyalist, Protestant, and English-speaking, while Lower Canada was heavily Catholic and French-speaking.

The 1840 union temporarily reversed the division. Discover Canada commits the named history of the two colonies to a specific later named event: "In 1840, Upper and Lower Canada were united as the Province of Canada." So the named 1791 division was reversed by the 1840 union — and then both colonies became founding partners of Confederation in 1867 as Ontario and Quebec. The named four founding provinces of the Dominion of Canada in 1867 were Ontario, Quebec, New Brunswick, and Nova Scotia. Today Ontario and Quebec together produce more than three-quarters of all Canadian manufactured goods. So when the test asks whether Upper Canada and Lower Canada are now known as Ontario and Quebec respectively, the source-precise answer is true.

The question is testing whether new citizens know the modern names of Upper and Lower Canada. Discover Canada commits to one named pairing: Upper Canada (later Ontario) and Lower Canada (later Quebec). The right test answer matches that — true.

The wrong answer ("False") reverses the source — Upper Canada DID become Ontario, and Lower Canada DID become Quebec. The named name changes are exact. Only the true answer matches the source.
