What it includes, just so you know what the tier 1 is, is that it comes with the right experience and a team that can actually be deployed and is able to manage that. Tier 2s have more experience, and they can go, but they would require the right level of experience to be able to lead them.
Tier 3 is what the Canadian Armed Forces would do. It's on the mop-up side. When the Canadian Armed Forces deploy in these types of situations, it frees up the tier 1 and tier 2 firefighters to go to fight the other fires, and the Canadian Armed Forces come in for the mop-up.
