The terrorist attack that took place here in Ottawa two years ago is one example. We saw that there was a problem with security services on the Hill and with the RCMP.
The maritime patrol is in a somewhat similar situation. If something happens and you can't deal with it, you call on the Royal Canadian Navy or the RCMP to obtain resources.
For instance, if you arrive somewhere and see that the Chinese have settled in and are drilling, what can you do besides report it? Aside from telling the Chinese to leave, you have no recourse.
