Madam Speaker, there are three core elements of ecological integrity: preserving and protecting natural biodiversity, which is the range and number of species; the natural processes, which the member's question relates to; as well as limiting unnatural stressors.
In the context of wildfires, Parks Canada has never let a wildfire burn in any park if there is human habitation nearby. Therefore, that is a limit. It is a natural limit and it makes sense. As I mentioned before, with the Carolinian forests, fires are not a natural stressor. Fires can occur in any place in Canada, but they are not part of the natural ecosystem type known as the “Carolinian forest” as opposed to the boreal, which clearly is a fire-driven ecosystem. Replenishment, rebirth, and new forests happen in the boreal through fire. However, even in the boreal forest, Parks Canada would not allow a boreal forest fire to burn out of control and threaten a community.
Therefore, there are common-sense limits to this, and Parks Canada has always applied them.
