On April 17th 1982, Queen Elizabeth II gave Canada its biggest step towards total independence. She signed the Canada Constitution Act of 1982 to replace the British North America Act of 1867. It was almost 100 years before in 1763 at the Treaty of Paris, the Canada we know today first started to take shape after the British gained territory from France.
The landmark signature by Queen Elizabeth II gave Canada a whole new set of fundamental laws and civil rights, marking Canadian independence to amend their own Constitution without first requiring approval from Britain. Congratulations Canada!
