How did flooding affect Canada's environment and wildlife?

Floods are largely produced by fluctuations in the height of rivers, lakes, and seas that occur naturally. Floods are the most prevalent natural hazard in Canada, and one of the most expensive, according to Public Safety Canada. Floods have wreaked havoc across Canada, with many of the worst occurring along major river systems that run through densely populated regions. Flooding due to climate change is expected to become more common as the twenty-first century continues, particularly in coastal parts of the country, according to scientists.

Explanation:

These maps serve as the foundation for provincial and local policies, rules, ordinances, and public awareness campaigns. New houses and businesses are discouraged (but not banned) from being built in these flood zones in favour of protecting the area for parks and other open spaces, recreation facilities, and animal habitat. The initiative has effectively exposed provincial and local governments to the need for a more holistic approach to flood damage reduction, including flood forecasting and warning systems, emergency measures, structural flood control measures, and land-use planning.
