This act united Upper and Lower Canada into one colony.

• A. Act of Union
• B. Confederation
• C. Red River Resistance
• D. Federal Powers

Answer: (A)

This question tests understanding of how Canada’s early political units were joined together under a single colonial administration. An Act of Union, implemented in 1841, merged the two separate colonies—Upper Canada (Ontario) and Lower Canada (Quebec)—to form the Province of Canada, creating two regions within one colony called Canada West and Canada East. It established a single parliament for the whole province, which is exactly what “uniting Upper and Lower Canada into one colony” describes. This move set up the later steps toward Canada’s federation, but it is distinct from Confederation in 1867, which created Canada as a country with a federal system. The Red River Resistance relates to Manitoba’s situation in the 1860s–70s, and Federal Powers refers to how authority is divided in a constitution, not to uniting the two Canadas.
