Except that it isn't. The Canadian Coast Guard is a purely civilian organization. For example, they don't partake in the war on drugs like their American counterparts do, and they don't have weapons either.
Although CCG personnel are neither a naval nor law enforcement force, they may operate CCG vessels in support of naval operations, or they may serve an operational role in the delivery of maritime law enforcement and security services in Canadian federal waters by providing a platform for personnel serving with one or more law enforcement agencies.
Interesting, so it's more of a civilian paramilitary organization? I'd say the vessels are still needed, even if it's not directly military
