The boreal forest in Canada has an area of over 1 million square miles, encompassing more than half the total land space. About 0.2% of it is harvested each year and, by law, is to be immediately replanted. One could leave the coast of Labrador and walk all the way to Alaska and never come across a town, a road or a single human being. The vast majority is inaccessible by road - it's by foot or by air. That's it.
There is no "managing" such land. Not by Canada and not by the US. Nobody is going to crisscross that territory with roads with the sole goal (hope) of managing it. For one, it would cost an incalculable fortune and be a Quixotic exercise in futility anyway.
Wildfire is the natural way that the boreal forest regenerates itself. The primary reason for the increase in the number, size and intensity of these wildfires is climate change. Canada is warming at twice the rate of the world average. It has created multiple years of severe drought conditions and the changing weather patterns have lead to more lightning strikes. And, since lightning doesn't need a road, the largest and most destructive fires tend to be in very remote areas, due to their inaccessibility. Lightning causes half of all wildfires, but is responsible for over 90% of area burned.
If these politicians want to see a reduction in wildfire damage and smoke, we have to stop emitting greenhouse gasses. Then, we will have to wait several generations to see the effects. Of course, politicians don't care about what happens beyond the next election cycle, never mind during the next century.
