Final answer:
Queen Elizabeth II is on the Canadian quarter due to Canada's history and ongoing ties with the United Kingdom. Formed under the British North American Act of 1867, Canada remained part of the British Empire with the British monarch as the head of state. Queen Elizabeth II currently holds this position and is recognized as the Queen of Canada.
Step-by-step explanation:
Queen Elizabeth II appears on the Canadian quarter because of Canada's historical ties with the United Kingdom. The British North American Act of 1867 unified various British colonies, forming what is now modern-day Canada. Despite having the ability to govern itself, this new federation, known as the Dominion of Canada, remained part of the British Empire with the reigning British monarch as its ceremonial head of state.
Today, Queen Elizabeth II continues to serve as the Queen of Canada, a separate title from her role as Queen of the United Kingdom. This is why her image is used on Canadian currency, including the quarter, symbolizing the historical connection and the ongoing relationship Canada maintains with the British monarchy.
