Video not available in the USA. In any case, forest fires are a natural occurrence. They're required to clear away the brush that lets the trees propagate and grow. Often, we put out fires to protect homes and people that naturally would have burned. That creates a lot more brush than should be there. So then when a fire start, we can't control it. It really gets out of hand and destroys the trees as well.
When I visited Grand Canyon last year, I noticed piles and piles of brush that had been gathered for pickup later and removal. The government was clearing away the brush that fires use to eliminate naturally.
If it gets warmer, with more storms, there probably will be more forest fires started. On the other hand, warmer climate has made more land open for forests to grow. Up where you live in Canada, the tree line is moving north as well as up mountains because of higher temperatures. More trees, more birds, more insects, more deer, more wolves, more bears, more people who can live there. It's a good thing.
