Royal Canadian Navy mutinies 1949

In 1949, some members of the Royal Canadian Navy (RCN) didn't agree with the way things were being run in the Navy. Some of them got together and rebelled against their leaders, which is called a "mutiny". This caused a lot of problems for the Navy and their leaders had to think of ways to fix the situation. In the end, the Navy leaders changed some of their rules so that the members of the RCN would be more satisfied. Many of the people involved in the mutiny were punished, so that other members of the RCN would know that mutiny is not accepted.
