Why did the British divide the colony of Quebec into upper and lower Canada?

The British divided the colony of Quebec into Upper and Lower Canada in 1791 as part of the Constitutional Act, aiming to address the distinct cultural and linguistic differences between English-speaking settlers in the west (Upper Canada) and French-speaking residents in the east (Lower Canada). This division allowed for more localized governance and representation, accommodating the needs of both groups while promoting British interests in the region. The separation also aimed to prevent potential conflicts and facilitate the assimilation of French Canadians into British colonial society.
