What British prime minister divided Canada into two parts?

The British Prime Minister who divided Canada into two parts was Sir John A. Macdonald. He played a crucial role in the Confederation of Canada in 1867, which created the Dominion of Canada by uniting the provinces of Ontario, Quebec, New Brunswick, and Nova Scotia. While Macdonald was instrumental in shaping Canada, it’s important to note that the division into two main linguistic and cultural regions—English-speaking and French-speaking—was more a reflection of existing societal divisions rather than a direct action of dividing the country.
