The Halifax Police does not maintain deep sea vessels. The RCMP does not interdict cargo vessels in international waters. They don't have satellite tracking, they don't handle international waters. They don't maintain boarding parties, they don't train for naval combat. They don't do this because their work happens on land.

Whats more NATO is a military organization, if Canada is going to be receiving intelligence from other militaries it needs to be contributing to the group. If it wants to know if a UK nuclear submarine is conducting trials near Canadian waters it needs submarines or it will not be informed. If that submarine founders and requires a recovery team which could very well affect Canadian interests, and Canada does not have a military Canada will be ignored.

When Canada has submarines Canada will be informed as a matter of course and a matter of joint safety. If Canada is a member of NATO it will be a part of any operation to recover that submarine.

Not exclusively but civilian teams do not routinely require the level of training and equipment which would justify them purchasing military grade equipment for disaster relief. You can't deploy a civilian team overseas in hostile conditions the way you can do so with a military team. The civilian teams do not train with the US military and if there was a major natural disaster you are going to be wanting the logistical expertise of the United States Military getting the food and supplies to isolated locations.

Because that detracts from their ability to handle their every day operations. the police routinely liaise with military when it changes jurisdictions or when they have a subject of mutual interest. But the fact is they do not handle these issues on a regular basis and they have no interest or capability of doing so.

If you have a hijacked plane in the air that is going to be used as an improvised missile what is that police officer going to do? Run outside and try to shoot it down with his pistol? If you have a plane which is unresponsive, but you don't know if the pilots are unconscious, if the plane has been taken hostage, or if they had a radio failure, what are you going to do? Just hope for the best?

Hardly, you can still mitigate damage, potentially even avert it.

Yes, but if the terrorists get on that plane, it is better to have the military there to force them to land at an Air Force base where JTF2 is waiting to storm that plane and take them out should hostage negotiations fail.

No, large portions of your country do not make sense to inhabit. If someone is going to immigrate to Canada they are going to immigrate to somewhere there is a job.
