How long New France last before conquered?

Answer 1

New France lasted for about 150 years, from its founding in 1534 until it was effectively conquered by the British in 1763. The most significant event leading to its downfall was the Treaty of Paris, which marked the end of the Seven Years' War and resulted in France ceding most of its North American territories to Britain. The formal transfer of power occurred with the signing of the treaty on February 10, 1763.
