Why were some people in Canada east against confederation?

Some people in Canada East opposed confederation due to concerns about losing their cultural identity and political power, particularly the French-speaking population who feared marginalization in a predominantly English-speaking federation. Additionally, there were worries about economic disparities, as many believed that joining a larger confederation would disadvantage their local industries and agricultural interests. Some also felt that the interests of Canada East would be overshadowed by those of more populous regions like Ontario.
