What maritime colonies did not want to join confederation?

The maritime colonies that were hesitant or opposed to joining Confederation in 1867 included Prince Edward Island, Nova Scotia, and New Brunswick. Many residents of these colonies were concerned about losing their autonomy, the potential for increased taxation, and the fear of economic disadvantages. Ultimately, while New Brunswick and Nova Scotia did join Confederation, Prince Edward Island initially opted out and only joined in 1873 after addressing some of its concerns.
