Many of our native species might struggle for survival and lose, affecting Canada's biodiversity. Altered snow and ice conditions will disrupt navigation, winter sports and tourism in Ontario and Quebec. Changes in timing of spring break-up could affect flooding. Longer and warmer growing seasons in Canada might allow for higher-yield crops and these could be grown further north. But climate change will also alter precipitation patterns.
Predictions are for more precipitation in northern Canada and less in the south.
This means that some currently productive southern Canadian farm lands would have more frequent and severe droughts, with a net loss in crop production. With more drought, forest fires and severe storms, the strain on our economy would be in the billions of dollars. It would cost less to heat our homes, but more to cool them. Greater variability of river runoff in several provinces will affect hydroelectric power production.
