Did the creation of a confederation negatively or positively impact Canada and its peoples?

A meeting to determine if Canada should become a confederation

There are many advantages and disadvantages to becoming a confederation. One advantage is military strength as joining forces with another pre-country which in all probability has a military force of its own further enables a colony defend themselves. Another advantage in the joining of the colonies would be that there would only need to be one governor which would greatly increase their ability to make decisions. A disadvantage concerns the issue of debt as both colonies' deficits are consolidated. However, other countries or colonies might feel threatened by the new country's  power. With the joining of the colonies, their government money would be combined and it would have a so they could build more for their new country and they would receive more tax money from the people of their country. Becoming a confederation could be a disadvantage to minorities such as the French-Canadians, but it's good for the English-Canadians.
