What were the reasons for Newfoundland for not joining confederation?

Answer 1

1st of all, they were more interested in their ties with Britain and the queen.

2nd, the CPR would not extend to them.

3rd, being far away from the government in Ontario, they would not have much say in matters

Answer 2

Of course, Newfoundland did eventually join, and remains a Canadian province to this day, but there was resistance to joining Confederation based on a sense of nationalism. They took pride in being a sovereign state of their own, and didn't want to be dominated by the more populous and wealthier regions of Canada.
