Question: Which agreement (failed) tried to amend the Constitution in 1990?

Answer options:

• Charlottetown Accord ✅ Meech Lake Accord
• Kelowna Accord
• Calgary Declaration

Correct answer: Meech Lake Accord

Explanation: The Meech Lake Accord is the correct answer because it was a 1987 agreement package of constitutional amendments that officially failed in June 1990 after failing to secure unanimous provincial ratification. The Charlottetown Accord is incorrect because it was a subsequent constitutional proposal that failed in a 1992 national referendum, while the Calgary Declaration and Kelowna Accord were much later initiatives. Officially, Discover Canada highlights these attempts to illustrate the complex history of Canadian federalism and constitutional negotiations. For the exam, candidates should memorize the specific years and outcomes of both the Meech Lake and Charlottetown Accords to avoid confusing these two major historical events.
