The decision to expand the role of the Canadian Coast Guard or keep it as it is, is really a question of government policy.
You undoubtedly know that in the United States, the U.S. Coast Guard is a service branch of the armed forces. That is not the case in Canada. The Canadian Coast Guard deals with fisheries and oceans, in particular, and plays a small law enforcement role.
We have to decide what we want our Coast Guard and our Royal Navy to be. Once the direction is given, both organizations will handle responding to demands.
